調回函數,這樣用,我只能收到1次字串後我就再也收不到下次字串了,請問這會是什麼原因呢?找了好幾天就是沒找到原因.... void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { /* Prevent unused argument(s) compilation warning */ //UNUSED(huart); /* NOTE : This function should not be modified, when the callback is needed, the HAL_UART_RxCpltCallback can be implemented in the user file. */ if(huart->Instance == USART1) { Uart1.write = (++Uart1.write == uart1_buffer_size) ? 0 : Uart1.write; Uart1.buffer[Uart1.write] = Uart1.Rx_buffer[0]; HAL_UART_Receive_IT(&huart1,(uint8_t*)Uart1.Rx_buffer,1); } } |
