BTW, I am using HAL libraries in STM32CubeIDE and HAL_UART_Receive(huart, pData, Size, Timeout) to read the contents of UART buffer. There is no way to send a string that is changing its length runtime, I have tried with various declarations, inside and outside while loop, but if I don't declare a fix length string (char buffer [30] for example), HAL is not taking it. Nếu u8_RxData nhận được là khác kí tự Enter (giá trị 13 trong bảng ASCII), ghi giá trị u8_RxData vào u8_RxBuf sau đó tăng giá trị _RxIndex. 2020 · Tìm hàm RxCpltCallback sau đó cấu hình như sau.
