Hello! I'm using STM32F407 processor. When I'm trying to send 1 byte via USART-DMA (for example 0x72) I get two bytes "72 72" in terminal.If I send two or more bytes everything is okay. If I send something from terminal I can't receive one byte, only two or more bytes can be received. Maybe someone can help to solve this problem. Thanks.
