Webb26 feb. 2014 · Non-static variables are called local variables, and exist only on the stack while that particular instance of the function is running. When the function returns, that local variable is thrown away. So if you declare static int x and let x=5, and then return, next time your function is called, x will still be 5. Local variables don't do that. Webb2. 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. giggleswick yorkshire england
