Web2. Keep the initialization code for UART. 3. Modify code to use my own function for starting Rx and UART IRQ handler, where I could handle my buffer freely. Of course, I could refer to the provided HAL code on how to access UART registers. Actually you have to add ''USART1_IRQHandler'' in your code to use interrupt mode. WebWell, it's to do with the implementation on STMicroelectronics chipsets. The designers of the STM32 HAL drivers have not done a fantastic job being faithful to the ARM documentation, so there are various caveats, omissions, and a few 'unusual' labels that can be found when writing IRQ driven UART. ...
