안녕.

HAL_UART_Emul_Receive_DMA 및 HAL_UART_Emul_Transmit_DMA를 사용하고 있습니다.

1Byte R/W를 시도 중입니다. stm32 go Error_Handler();

코드를 어떻게 변경해야 하나요?

감사합니다.

hi.

I am using HAL_UART_Emul_Receive_DMA and HAL_UART_Emul_Transmit_DMA.

Attempting 1Byte R/W. stm32 go Error_Handler();

How should I change my code?

Thank you.

 Are you using STSW-STM32156 example ?

Could you please give more details about your hardware? Are you using NUCLEO-F401RE boards?

Thank you.

Hi, KDJEM1.

Yes, I'm using en.stsw-stm32156.zip.

I'm using stm32f4-discovery(stm32f401vct) board.

en.stsw-stm32156.zip code works very good, but it's receiving 2Byte adding last Byte 0x00 just write 1Byte.

So, How should i change code. also i want receive DMA using circuler mode.

Thank you.
