Forum Post: RE: MCU-PLUS-SDK-AM243X: Need Help Understanding GPIO Input Interrupt

Hello Keito, Thanks for your query. Are you trying to write the complete code by yourself? Please take reference from the existing GPIO input interrupt example already present in the SDK. Are you calling Sciclient_gpioIrqSet() function generated by sysconfig in the main code? This function has the required code to route your interrupt to destination code. You will need to change the src_index set in the Sciclient_gpioIrqSet() API to specific pin number to configure GPIO as pin interrupt. Please refer faq-sk-am62-how-to-configure-the-gpio-interrupt-on-am62x-in-mcu-sdk for details. Regards, Tushar
