;* File Name : startup_stm32f407xx.s
;* Author : MCD Application Team
;* Description : STM32F407xx devices vector table for MDK-ARM toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the CortexM4 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.
;* <<< Use Configuration Wizard in Context Menu >>>

;* File Name : startup_stm32l431xx.s
;* Author : MCD Application Team
;* Description : STM32L431xx Ultra Low Power devices vector table for MDK-ARM toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the Cortex-M4 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

2018-09-13 (REL_1_6_0) Christian Walter <cwalter@embedded-solutions.at>
Notes: Changed licensing for mbfuncdisc.c. Updating licensing info
and contact details in core stack.
2010-05-06 (REL_1_5_0) Christian Walter <cwalter@embedded-solutions.at>
Notes: Added support for Atmel AT91SAM3S (Cortex M3) for IAR.
Detailed notes:
- FEATURES (ATSAM3S) : Added new port.
2007-08-28 (REL_1_4_0) Christian Walter <wolti@sil.at>:
Notes: Added support for HCS08. Fixed some small bugs in the documentation
for the porting layer.
Detailed notes:
- FEATURES (HCS08) : Added new port.
- BUGS (ALL) : Fixed some small bugs in the porting guide.
2007-07-17 (REL_1_3_0) Christian Walter <wolti@sil.at>:
Notes: Added ARM7/AT91SAM7X port. Added Linux/TCP port from Steven Guo.
Detailed notes:
- FEATURES (ARM7): Added ARM7/AT91SAM7x port.
- FEATURES (LINUX): Added Linux/TCP port from Steven Guo.
- BUGS (ALL): Fixed bug in <eMBFuncReadInputRegister> where the high
byte of the register count was ignored. This does not have a
practical impact because the actual number of registers is always
lower.
2007-07-17 (REL_1_3_0) Christian Walter <wolti@sil.at>:
Notes: Added Linux/TCP port. Fixed bug in MSP430 port.
Detailted notes:
- FEATURE (LINUX): Added Linux/TCP port.
- BUGS (MSP430): Fixed bug with calculating the timer value.
2007-04-25 (REL_1_2_0) Christian Walter <wolti@sil.at>:
Notes: Added LPC214X ARM port with Keil compiler. Added Z8Encore port for
Z8F6422 microcontroller.
Detailed notes:
- FEATURE (ARM): Added LPC214X ARM port for Keil ARM 2.41.
- FEATURE (Z8ENCORE): Added Z8F6422 for Z8Encore using the ZDS II - Z8
Encore! development tools.
2007-02-18 (REL_1_1_2) Christian Walter <wolti@sil.at>:
Notes: Fixed typo with the defined defining the supported Modbus
functions. Fixed bug when illegal slave address was passed to eMBInit
where the error was not detected. Fixed typo in the holding registers
where the frame for write multiple registers was parsed with the wrong
constants. The fix is not critical because the values matched. Fixed bug
in discrete input registers implementation where the frame was not parsed
correctly. Added new support for a CodeWarrior Coldfire port.
Detailed notes:
- BUG (ALL): Modbus functions are compiled into the stack conditionally
by changing the MB_FUNC_XXX defines to either true(1) or false(0).
The defines for MB_FUNC_READ_HOLDING and MB_FUNC_WRITE_HOLDING
were wrong.
- BUG (ALL): eMBInit did not correctly check for addresses. Therefore
is was possible to start the Modbus stack with an address of 0
or one > 247.
- BUG (ALL): eMBFuncWriteHoldingRegister should use
MB_PDU_FUNC_WRITE_MUL_ADDR_OFF and not MB_PDU_FUNC_READ_ADDR_OFF.
- BUG (ALL): eMBFuncReadDiscreteInputs calculated the number of discrete
registers to read wrong.
- FEATURE (ALL): Fixed some warnings in the code.
2006-11-19 (REL_1_1_1) Christian Walter <wolti@sil.at>:
Notes: Fixed bug in Read/Write Multiple Registers function where
the registers addresses where calculated wrong.
Fixed bug in RTU and ASCII with the resource allocation in case of
an error.
Changed license to BSD style licsense.
Detailed notes:
- OTHER (ALL): License is now BSD for protocol stack.
- BUG (ALL): The registers address received in a Modbus frame
must be converted to application addresses. The code for this
conversion was missing and therefore has lead to error when
this function was used (Registers of by one, Start at > 1).
- BUG (ALL): If the serial initialization within the porting fails
a timer is still allocated in eMBRTUInit and eMBASCIIInit. This
can lead to a memory leak depending upon the implementation of the
porting layer.
- FEATURE (MCF5235): Added sample shell scripts for testing.
- FEATURE (MSP430): Added sample shell script for testing and
changed default values to match the other ports.
2006-10-30 (REL_1_1_0) Christian Walter <wolti@sil.at>:
Notes: Added support for Read/Write Multiple Registers function
(0x17). Added some tips to reduce memory requirements.
Added MSP430 Port for GCC and Rowley Crossworks.
Detailed notes:
- FEATURE (MSP430): Added new MSP430 port.
- FEATURE (ALL): Added support for Read/Write Multiple Registers
function (0x17). The implementation simply makes two callbacks
to the eMBRegHoldingCB function where first the values are
written and then the other register values are read.
- FEATURE (ALL): Added some tips on reducing memory requirements
with the protocol stack.
2006-10-30 (REL_1_0_5) Christian Walter <wolti@sil.at>:
Notes: eMBDisable and eMBClose can now be called multiple times
which makes shutdown of the protocol stack easier.
Fixed bug in RTU state machine where we switched from the
error state immediately to the idle state. Correct behaviour
would be to wait till the end of frame.
Added new STR71X GCC port which uses only freely available tools
like GNU ARM, OpenOCD (Wiggler) and GDB.
Detailed notes:
- FEATURE (STR71X): Added GCC standalone port which does not
depend on the Rowley Crosswork tools.
- FEATURE (ALL): eMBDisable can now be called multiple times
and returns MB_ENOERR in case is was already disabled.
eMBClose also supports beeing called multiple times in
which pvMBFrameCloseCur( ) is called when the protocol stack
is in state STATE_DISABLED.
- BUG (RTU): Fixed bug in xMBRTUReceiveFSM where the error
state is immediately left because of a missing break. Instead
we should wait till the damaged frame is finished.
2006-10-11 (REL_1_0_4) Christian Walter <wolti@sil.at>:
Notes: Fixed bug when more than 255 coils are requested. Fixed bug in
Linux/Cygwin port when not all bytes could be written by the first
call to write. Added support for removing previously registered
function handlers.
Detailed notes:
- BUG (ALL): mbfunccoils contained a bug which limited the amount
of coils to read to 255.
- BUG (LINUX): prvbMBPortSerialWrite contained a bug in the loop
which writes the RTU/ASCII frame to the serial file descriptor.
If not all bytes where written in the first call or write was
interrupted the sent frame is corrupted.
- FEATURE (ALL): eMBRegisterCB now supports NULL as handler
argument in which case a previously registered function
handler is deregistered from the protocol stack.
2006-09-27 (REL_1_0_3) Christian Walter <wolti@sil.at>:
Notes: Added new functions to support registering of custom callback
handlers. This makes it possible to implement new Modbus function
codes without touching the protocol stack.
New port for ATMega128 added. Thanks to Richard C Sandoz Jr. for
the patches.
Detailed notes:
- FEATURE (ALL): Added support for registering new functions handlers
with eMBRegisterCB.
- FEATURE (AVR): Added patches from Richard C Sandoz Jr. for ATMega128
2006-09-06 (REL_1_0_2) Christian Walter <wolti@sil.at>:
Notes: Fixed bug in FreeRTOS porting layer for STR71X/lwIP target where
memory is not freed in the sys_arch_thread_remove function.
Synched MCF5235TCP port with the FreeRTOS/lwIP port for the STR71X.
Detailed notes:
- BUG (STR71XTCP): Sys_arch_thread_remove did not free the memory from
the TCB.
- BUG (STR71XTCP): Unnecessary call to vTaskSuspendAll removed.
- BUG (STR71XTCP): Bug with counting variable. The first to lwIP tasks
got the same name (lwIP0).
- FEATURE (MCF5235TCP): Enhanced functions from the STR71X/lwIP port
merged into the Coldfire port.
2006-09-04 (REL_1_0_1) Christian Walter <wolti@sil.at>:
Notes: Fixed bug in serial driver for STR71x target when the ring buffer
overflows.
Detailed notes:
- BUG (STR71XTCP): Under high load the ring buffer in the serial driver
functions might overflow. There was an error with counting the number
of received characters which corrupted received frames.
Now receiver correctly recovers in case of dropped bytes.
2006-09-04 (REL_1_0) Christian Walter <wolti@sil.at>:
Notes: Added support for ATmega8, ATmega16, ATmega32, ATmega169 and
RS485 drivers in the AVR support. Special thanks to Tran Minh Hoang
for his contribution.
Added a new lwIP port for the STR71X target which uses one serial
interface for a PPP connection. This can be used for remote Modbus/TCP
devices in combination with a Modem (E.g. GPRS or Analog).
Detailed notes:
- FEATURES (AVR): Integrated patches from Tran Minh Hoang to support the
ATmega8, ATmega16, ATmega32, ATmega169 controllers.
- FEATURES (AVR): Added support for RS485 drivers in the AVR code. The
example supports the DS76176.
- FEATURES (STR71XTCP): implemented function in STR71X/lwIP porting layer
to remove running tasks.
- FEATURES (STR71XTCP): added new thread creation function in STR71X/lwIP
porting layer which allows specifing the stack size.
- BUGS (STR71XTCP): pppOpen defined in ppp.c does not check the return
value of sys_thread_new. If task creation fails the system crashes.
- BUGS (STR71XTCP): pppMain must not return - Instead it should remove
its task from the scheduler.
2006-08-30 (REL_9) Christian Walter <wolti@sil.at>:
Notes: Added lwIP port for the MCF5235 target. The lwIP part is
generic and therefore FreeModbus now works on any target with
lwIP support.
Detailed notes:
- FEATURES: Incoperated MCF5235 FreeRTOS/lwIP port done by the
author in this project.
- FEATURES: Added lwIP port for FreeModbus
- FEATURES: Added demo application for FreeModbus and lwIP.
2006-08-22 (REL_0_82) Christian Walter <wolti@sil.at>
Notes: Fixed bug with Modbus ASCII support
Detailed notes:
- BUG: During the last upgrade an error was introduced in the
initialization code of Modbus ASCII and therefore ASCII
support was broken. The bug is fixed now and was tested with
the Win32 port.
2006-08-22 (REL_0_81) Christian Walter <wolti@sil.at>
Notes: Added porting guide
Detailed notes:
- OTHER: Added a new porting guide to the documentation.
- OTHER: Added a empty example for new ports to the project as a
starting point.
2006-08-01 (REL_0_8) Christian Walter <wolti@sil.at>
Notes: Added Linux RTU/ASCII port.
Detailed notes:
- FEATURES: Added a new Linux RTU/ASCII port. The port should work
on any Linux distribution and it should be possible to run it
on uCLinux.
2006-06-26 (REL_0_7) Christian Walter <wolti@sil.at>
Notes: Changed the WIN32 serial port to better fit into the design.
Detailed notes:
- OTHER: Design of the WIN32 serial port changed. The polling function
for the serial device are now called from the event loop.
- OTHER: Debugging uses the same interface as the WIN32/TCP port.
2006-06-25 Christian Walter <wolti@sil.at>
Notes: Initial work on a Modbus/TCP port is available. The port includes
an example for a Win32 port which uses the Winsock API.
Detailed notes:
- FEATURES: added required functions to core protocol stack to support
a Modbus/TCP implementation.
- FEATURES: added a Win32 port for the Modbus/TCP core. The port is
currently limited to one concurrent client.
- OTHER: The implementation of eMBClose to shutdown the protocol stack
was changed to unify it with the new Modbus/TCP code.
-
2006-06-18 Christian Walter <wolti@sil.at>
Detailed notes:
- OTHER: while working on the Win32 port some line feeds got
wrong. Also some source files used tabs instead of spaces.
- OTHER: prototypes for xMBUtilSetBits and xMBUtilGetBits fixed.
usNBits should be ucNBits by convention.
2006-06-17 Christian Walter <wolti@sil.at>
Notes: Fixed various bugs with the Win32 port
Detailed notes:
- FEATURES: implement shutdown functionality for protocol stack.
- FEATURES: protocol stack can be enabled and disabled during runtime.
- FEATURES: interface functions now do more error checking. For
example if eMBPool is called in an uninitialized state.
- FEATURES: extended Win32 demo application to use the new features.
- BUG: fixed bug in Win32 demo for ASCII mode.
2006-06-16 Christian Walter <wolti@sil.at>
Notes: The new version includes a new port for the
Win32 platform
Detailed notes:
- FEATURES: added Win32 platform
2006-05-14 Christian Walter <wolti@sil.at>
Notes: The new version includes a new port for the
Freescale MCF5235 processor.
Detailed notes:
- FEATURES: added new MCF5235 port.
- OTHER: fixed some missing code headers.
2006-05-01 Christian Walter <wolti@sil.at>
Notes: This version removes the t1.5 timers from the Modbus RTU
implementation because no one actually uses it and the CPU
load is very high. T
In addition some documentation cleanups has been done and the
ARM demo has been updated.
Detailed notes:
- FEATURES: the t1.5 timeout has been removed. Therefore only
one timer is required.
- BUG: the ARM demo project missed some files in the project
workspace and did not compile cleanly
2006-02-28 Christian Walter <wolti@sil.at>
Notes: This version includes support for two new command
(write multiple coils, read discrete input)
Detailed notes:
- BUG: some function used the wrong data types
- FEATURES: added support for write multiple coils function.
- FEATURES: added support for read discrete input.
- OTHER: some code cleanups with lint tool.
2006-02-28 Christian Walter <wolti@sil.at>
Notes: The new version 0.31 adds support for reading and writing the
coil registers and add some bug fixes.
Detailed notes:
- BUG: fixed bug with to small modbus requests being ignored.
- FEATURES: added support for write single coil function.
- FEATURES: added support for working with byte packed bit fields
to support coils and discrete inputs better.
- API: API for set slave id functions changed.
2006-02-26 Christian Walter <wolti@sil.at>
Notes: First public release which includes an ARM and AVR port.

* This is the list implementation used by the scheduler. While it is tailored

*
* xLists can only store pointers to xListItems. Each xListItem contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* descending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at

* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and

*
* Delay a task until a specified time. This function can be used by cyclical
* tasks to ensure a constant execution frequency.
*
* This function differs from vTaskDelay () in one important aspect: vTaskDelay () will
* cause a task to block for the specified number of ticks from the time vTaskDelay () is
* called. It is therefore difficult to use vTaskDelay () by itself to generate a fixed
* execution frequency as the time between a task starting to execute and that task
* calling vTaskDelay () may not be fixed [the task may take a different path though the
* code between calls, or may get interrupted or preempted a different number of times
* each time it executes].
*
* Whereas vTaskDelay () specifies a wake time relative to the time at which the function
* is called, vTaskDelayUntil () specifies the absolute (exact) time at which it wishes to
* unblock.
*
* The constant portTICK_RATE_MS can be used to calculate real time from the tick
* rate - with the resolution of one tick period.
*
* @param pxPreviousWakeTime Pointer to a variable that holds the time at which the
* task was last unblocked. The variable must be initialised with the current time
* prior to its first use (see the example below). Following this the variable is
* automatically updated within vTaskDelayUntil ().
*
* @param xTimeIncrement The cycle time period. The task will be unblocked at
* time *pxPreviousWakeTime + xTimeIncrement. Calling vTaskDelayUntil with the
* same xTimeIncrement parameter value will cause the task to execute with
* a fixed interface period.

/*
Changes from V1.2.0
+ Removed the volatile modifier from the function parameters. This was
only ever included to prevent compiler warnings. Now warnings are
removed by casting parameters where the calls are made.
+ prvListGetOwnerOfNextEntry() and prvListGetOwnerOfHeadEntry() have been
removed from the c file and added as macros to the h file.
+ uxNumberOfItems has been added to the list structure. This removes the
need for a pointer comparison when checking if a list is empty, and so
is slightly faster.
+ Removed the NULL check in vListRemove(). This makes the call faster but
necessitates any application code utilising the list implementation to
ensure NULL pointers are not passed.
Changes from V2.0.0
+ Double linked the lists to allow faster removal item removal.
Changes from V2.6.1
+ Make use of the new portBASE_TYPE definition where ever appropriate.
Changes from V3.0.0
+ API changes as described on the FreeRTOS.org WEB site.
Changes from V3.2.4
+ Removed the pxHead member of the xList structure. This always pointed
to the same place so has been removed to free a few bytes of RAM.
+ Introduced the xMiniListItem structure that does not include the
xListItem members that are not required by the xListEnd member of a list.
Again this was done to reduce RAM usage.
+ Changed the volatile definitions of some structure members to clean up
the code where the list structures are used.
Changes from V4.0.4
+ Optimised vListInsert() in the case when the wake time is the maximum
tick count value.

/*
Changes from V1.01
+ More use of 8bit data types.
+ Function name prefixes changed where the data type returned has changed.
Changed from V2.0.0
+ Added the queue locking mechanism and make more use of the scheduler
suspension feature to minimise the time interrupts have to be disabled
when accessing a queue.
Changed from V2.2.0
+ Explicit use of 'signed' qualifier on portCHAR types added.
Changes from V3.0.0
+ API changes as described on the FreeRTOS.org WEB site.
Changes from V3.2.3
+ Added the queue functions that can be used from co-routines.
Changes from V4.0.5
+ Added a loop within xQueueSend() and xQueueReceive() to prevent the
functions exiting when a block time remains and the function has
not completed.
Changes from V4.1.2:
+ BUG FIX: Removed the call to prvIsQueueEmpty from within xQueueCRReceive
as it exited with interrupts enabled. Thanks Paul Katz.
Changes from V4.1.3:
+ Modified xQueueSend() and xQueueReceive() to handle the (very unlikely)
case whereby a task unblocking due to a temporal event can remove/send an
item from/to a queue when a higher priority task is still blocked on the
queue. This modification is a result of the SafeRTOS testing.

*
* VECTORED_IRQ_INTERRUPTS
*
* Enable vectored IRQ interrupts. If defined, the PC register will be loaded
* with the contents of the AIC_IVR register on an IRQ exception.
*
* STARTUP_FROM_RESET
*
* If defined, the program will startup from power-on/reset. If not defined
* the program will just loop endlessly from power-on/reset.
*
* This definition is not defined by default on this target because the
* debugger is unable to reset this target and maintain control of it over the
* JTAG interface. The advantage of doing this is that it allows the debugger
* to reset the CPU and run programs from a known reset CPU state on each run.
* It also acts as a safety net if you accidently download a program in FLASH
* that crashes and prevents the debugger from taking control over JTAG
* rendering the target unusable over JTAG. The obvious disadvantage of doing
* this is that your application will not startup without the debugger.
*
* We advise that on this target you keep STARTUP_FROM_RESET undefined whilst
* you are developing and only define STARTUP_FROM_RESET when development is
* complete.
*
* MC_FMR_FMCN_VAL
*
* Override the default Flash Mode Register FMCN value by defining
* MC_FMR_FMCN_VAL.
*
* MC_FMR_FWS_VAL
*
* Override the default Flash Mode Register FWS value by defining
* MC_FMR_FWS_VAL.
*

* Override the default Main Oscillator Register value by defining

*
* NO_WATCHDOG_DISABLE
*
* If defined, the watchdog will not be disabled.
*
* NO_USER_RESET
*
* If defined, user reset will not be enabled.
*
* NO_PROTECTION_MODE
*
* If defined, AIC protection mode will not be enabled. AIC protection
* mode allows the AIC_IVR register to be accessed by the debugger (for
* example through the memory or register window). With protection mode
* disabled accesses of the AIC_IVR register by the debugger are likely
* to disrupt interrupt behaviour.

FREEMODBUS 1.5 ATSAM3S EXAMPLE
==============================
REQUIREMENTS
============
This example contains a simple demo program for FreeMODBUS for the AT91SAM3S
Cortex M3 controllers on the SAM3S-EK [0] evaluation kit. It requires a wired
RS485 connection to a host processor and a MODBUS master software on the PC
side to be useful. Demo versions of MODBUS master stacks can be found in
[1], [2] and [3]. Commercial MODBUS stacks are available from [4].
INSTALLATION
============
The SAM3S-EK evaluation board should be modified as following to enable RS485
data transmission.
- Place Jumpers JP11, JP10 and JP12
- Place a solder drop accross R25
Warning: The RS485 shares data lines with USART1. It is therefore absolutely
necessary to set PA23 to a high level.
SOURCE
======
TESTING
=======
Start the MODBUS sample application and test if the input registers starting
at protocol address 1000 can be read. There are four registers values avai-
lable and the output should look like:
Polling slave (Ctrl-C to stop) ...
[1000]: 6474
[1001]: 0
[1002]: 0
[1003]: 0
Polling slave (Ctrl-C to stop) ...
[1000]: -8831
[1001]: 0
[1002]: 0
[1003]: 0
Polling slave (Ctrl-C to stop) ...
The simple testing utility used in the 'demo_rtu.bat' script can be found at
[3].
PROBLEMS
========
In case you can get no communication working make sure that the RS485 line is
biased correctly. The SAM3S-EK does not populate the RS485 bias resistors by
default and if you have a RS485 master which does not bias the lines either
you will get wrong characters. For this R24 and R30 on the bottom side of the
evaluation kit of the PCB should be populated.

/** \addtogroup efc_module Working with Enhanced Embedded Flash
* The EEFC driver provides the interface to configure and use the EEFC
* peripheral.
*
* The user needs to set the number of wait states depending on the frequency used.\n
* Configure number of cycles for flash read/write operations in the FWS field of EEFC_FMR.
*
* It offers a function to send flash command to EEFC and waits for the
* flash to be ready.
*
* To send flash command, the user could do in either of following way:
* <ul>
* <li>Write a correct key, command and argument in EEFC_FCR. </li>
* <li>Or, Use IAP (In Application Programming) function which is executed from
* ROM directly, this allows flash programming to be done by code running in flash.</li>
* <li>Once the command is achieved, it can be detected even by polling EEFC_FSR or interrupt.
* </ul>
*
* The command argument could be a page number,GPNVM number or nothing, it depends on
* the command itself. Some useful functions in this driver could help user tranlate physical
* flash address into a page number and vice verse.
*
* For more accurate information, please look at the EEFC section of the

* <li>Checks whether a region to be programmed is locked. </li>
* <li>Unlocks the user region to be programmed if the region have locked before.</li>

*
* \section Purpose
*
* The font.h files declares a font structure and a LCDD_DrawChar function

*
* The font10x14.c implements the necessary variable and function for a 10x14
* font.
*
* \section Usage
*
* -# Declare a gFont global variable with the necessary Font information.
* -# Implement an LCDD_DrawChar function which displays the specified
* character on the LCD.
* -# Use the LCDD_DrawString method defined in draw.h to display a complete
* string.
