WebApr 11, 2024 · Issue with two ERU interrupts and multiple interrupt functions. I am quiet new to Microcontroller programming and currently I am using Aurix microcontroller TC33 and I would need a help. I imported the code example with External Request Unit (ERU) to generate an interrupt for falling edge at an input pin. Webwe can configure the GPIO Mode as rising edge, falling edge or rising/falling edge to decide when to trigger interrupt. It is clear that the voltage should be 0v, when KEY0 and KEY1 are press, while the voltage should 3.3v, when WK_UP is press. So the GPIO Mode of PA15 and PC5 should be falling edge, while the GPIO Mode of PA0 should be rising ... request a gym location pokemon goWebYes it is possible.
