implementing modbus on UART

[hasan700]

Hi.
Your code is well described and good. I want to use it on STM32F103VET6 discovery board, and use UART1 port for modbus (not USB). I don't know how to do that and what codes I should use instead of those you used for USB.
Thank you very much...

Hi,
Could you implement it on UART?
I have the same problem :(
Thank you!

Hi, that's for a few months ago, I could , but very hardly!!!!!!!!! I know, that's very bad. you should use the codes in the library. sorry , I don't remember what I did exactly. Good luck!!!!!!!!!

Здравствуйте!
Спасибо за код, сэкономили мне пару минут ;)
Нашел ошибочку. В обработке 3 функции со строки 121 вместо

mb_buf_out[mb_buf_out_count++]=(st+nu)*2; // how many bytes we will send?
for(i=st;i<nu;i++)

следует записать

mb_buf_out[mb_buf_out_count++]=nu*2; // how many bytes we will send?
for(i=st;i<st+nu;i++)

Аналогичная ошибка и в 16 функции.
После этого работает нормально ;)

Thank you!

This library uses HAL, FreeRTOS and USART:

@sslobodyan Спасибо! пофиксил :)

@heroseller17 Hello!
my code not relying on any implementation. just put received bytes to ModBusInHandle, and send out anything from ModBusOutHandle queue.
