Usart Multiprocessor

[nimaltd]

I can not find any example for Usart Multiprocessor, It does not work.

I config on CubeMx and 

HAL_MultiProcessor_EnableMuteMode(&huart1);

HAL_MultiProcessor_EnterMuteMode(&huart1);

put this 2  lines.

Hello @nimaltd,

I think this is an example of UART being shared.

I hope it can help you.

After doing configuration on Cube and setting Address bit to 7 bits, The master should send first byte (address) or by 0x80. for example if the slave address is 0x01, the master should send 0x81.

but now i can not send data from slave to master. i am working on it...

slave code:

main()

.

.

HAL_MultiProcessor_EnableMuteMode(&huart1);

HAL_MultiProcessor_EnterMuteMode(&huart1);

HAL_UARTEx_ReceiveToIdle_DMA(&huart1, buf, sizeof(buf));

while (1)

{

}
