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.
