Dear Sir,
Now I am using HAL library ( STM32Cube_FW_L1_V1.8.0)
after setup USART 3, and
after running, in some case, I need to disable the transmit interrupt by using
__HAL_UART_DISABLE_IT(&UartHandle, UART_IT_TXE);
But then if I need to re-transmit some data from buffer, even using
HAL_UART_Transmit_IT(&UartHandle, (uint8_t*)aTxBuffer, TXBUFFERSIZE);
It will not transmit out any data nor having any USART interrupt.
Thanks!
Martin
