How to configuration exti with pins porta or portb? For examle how can i external interrept portb7 and porta6. And how can i systick interrupt use init and handler function?
Can you please provide full part number of the STM320 microcontroller, like STM32030? Or you can share the reference manual of your controller here.
Is it an evaluation board or a custom board?
