Oleg 889280dce5 Put init modbus function outside periphery 7 months ago
Oleg 6a6ca4cd3e Change modbus configuration logic 
COMM board asks CPU for modbus config now if it was not sent
earlier (for example after flashing COMM board)

Oleg 7ab4153cca Add cpu to comm modbus data handling 7 months ago
Oleg 31b3b12a81 Clean the project 7 months ago
Oleg 06518a828d Add modbus lib instead of original one 
1. All modbus classes are united in one (modbusRTU) class with
easier and clearier user interface

2. Temp variable for registers start address are created
(should be replaced for some getter function later)

3. 2 modbus register are sending in one message now without
its address. This requires some synchronization to be
implemented

4. There is a lot of garbage from previous modbus here.

Oleg 46d4b79e90 Add modbus. 
Init with CPU data. If COMM is removed and then installed back -
modbus will not work because CPU board will not send config data.
CPU board should detect reinstalling/reprogramming of COMM board and
send config data again (with asking software version)

Modbus here just work itself. There is no connection btw COMM and CPU
except sending config data

Oleg 4606a25db4 Clean more 7 months ago
Oleg 5db1783db5 Clean project. Modbus still working 7 months ago
Oleg 9feba6b8c9 It works now 
The problem was with InitCPUTimers dunction (it was commented).
But some fact was found: If you flash with correct software first
 - Modbus is working. Then, if you comment InitCPUTimers function and
flash CPU again. The Modbus still working! But, if you turn off the power
Modbus will not work after power up. The reason is unknown

1. Now method takes Uint62 instead of Uint32
2. Comment TA bit checking for not potentially make processor to stand in
endless loop if there is no answer from another node
3. The method do not set data lenght now. It should be set when MBOX
configuring
 8 months ago
Oleg d864977511 First test 
1. Add an arbitrator class to control all necessary periphery
main2.cpp represents it usage.
main.cpp without periphery class.

2. Add XINTF init and DigitalIO interface
3. Change DI/O MBOX length to 2 bytes instead of 3
 8 months ago
Oleg c692668f7b Expand CAN functionality.

Oleg 714f0265cc Merge branch 'feature/baseCAN' into dev 
CAN module is added here. This is not the can protocol for communication
between CPU and COMM boards, but common CAN protocol that must be
extended in the future
 8 months ago
Oleg 0246107428 Fix compile problem 
It started not to compile at all without changing anything manually
Some libs were deleted (because they was added automatically)

Add protection agaist accessing to MBOX with number >31
in transmitMsg method

Add TPL configuration in configTX method

Clear some garbage
 8 months ago
Oleg 0efa3cb375 Add changes in init functions 
Replace #define to enum for safety reasons

Now config function takes as an arguments not only baudrate, but
flags for most significant bit and self teset mode initialization.
All parameters have a default value now

Add protection against access to MBOX with number > 31 in every
possible functions

Remove some old code

;//
;// TITLE: Branch for redirecting code execution after boot.
;//
;// For these examples, code_start is the first code that is executed after
;// exiting the boot ROM code.
;//
;// The codestart section in the linker cmd file is used to physically place
;// this code at the correct memory location. This section should be placed
;// at the location the BOOT ROM will re-direct the code to. For example,
;// for boot to FLASH this code will be located at 0x3f7ff6.
;//
;// In addition, the example DSP2833x projects are setup such that the codegen
;// entry point is also set to the code_start label. This is done by linker
;// option -e in the project build options. When the debugger loads the code,
;// it will automatically set the PC to the "entry point" address indicated by
;// the -e linker option. In this case the debugger is simply assigning the PC,
;// it is not the same as a full reset of the device.
;//
;// The compiler may warn that the entry point for the project is other then
;// _c_init00. _c_init00 is the C environment setup and is run before
;// main() is entered. The code_start code will re-direct the execution
;// to _c_init00 and thus there is no worry and this warning can be ignored.

;// TITLE: Simple delay function
;//
;// DESCRIPTION:
;//
;// This is a simple delay function that can be used to insert a specified
;// delay into code.
;//
;// This function is only accurate if executed from internal zero-waitstate
;// SARAM. If it is executed from waitstate memory then the delay will be
;// longer then specified.
;//
;// To use this function:
;//
;// 1 - update the CPU clock speed in the DSP2833x_Examples.h
;// file. For example:
;// #define CPU_RATE 6.667L // for a 150MHz CPU clock speed
;// or #define CPU_RATE 10.000L // for a 100MHz CPU clock speed
;//
;// 2 - Call this function by using the DELAY_US(A) macro
;// that is defined in the DSP2833x_Examples.h file. This macro
;// will convert the number of microseconds specified
;// into a loop count for use with this function.
;// This count will be based on the CPU frequency you specify.
;//
;// 3 - For the most accurate delay
;// - Execute this function in 0 waitstate RAM.
;// - Disable interrupts before calling the function
;// If you do not disable interrupts, then think of
;// this as an "at least" delay function as the actual
;// delay may be longer.
;//
;// The C assembly call from the DELAY_US(time) macro will
;// look as follows:
;//
;// extern void Delay(long LoopCount);
;//
;// MOV AL,#LowLoopCount
;// MOV AH,#HighLoopCount
;// LCR _Delay
;//
;// Or as follows (if count is less then 16-bits):
;//
;// MOV ACC,#LoopCount
;// LCR _Delay
;//

<Operation> is the operation such as Erase, Program...
For portability for users who may move between the F2808, F2806 and
F2801, the following macro definitions are supplied.
Using these macro definitions, the user can use instead make a generic
call: Flash_<Operation> and the macro will map the call to the proper
device function
Note except for the toggle test function, all of the function prototypes
are compatible with F281x devices as well.

Notes:
Memory blocks on F28335 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

Notes:
Memory blocks on F28335 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

The 'targetConfigs' folder contains target-configuration (.ccxml) files, automatically generated based
on the device and connection settings specified in your project on the Properties > General page.
Please note that in automatic target-configuration management, changes to the project's device and/or
connection settings will either modify an existing or generate a new target-configuration file. Thus,
if you manually edit these auto-generated files, you may need to re-apply your changes. Alternatively,
you may create your own target-configuration file for this project and manage it manually. You can
always switch back to automatic target-configuration management by checking the "Manage the project's
target-configuration automatically" checkbox on the project's Properties > General page.
