Hi,

We are using STM32f429 microcontroller for our project.

 

I'm having problem receiving buffer in  USART DMA data between two stm32f429 controllers with the Baud rate of 9600.

 

We are able to receive all the  data every time, but frame of data will be shifted in received buffer,

 

EX:

  1. Receive data  "HELLO" (first time)
  2. Received data  "LLOHE"(second time)
  3. Received data  "OHELL"(third time)

 

                This keeps shifting like this every time.

 

Kindly suggest .

 

Thanks,

Utpal
