HAL_UART_Transmit_IT only work for Size 4 or smaller
Hello HankB,
the code is as simple as:
uint8_t aTxStartMessage[] = “\n\r ****UART-Hyperterminal communication based on IT ****\n\r Enter command :\n\r”;
HAL_UART_Transmit_IT(&huart4, (uint8_t*)aTxStartMessage, SIZE);
if SIZE is more than 4, I get an overrun error. I had to disable the Error Interrupt, and everything works just fine....
Thanks!
