How to setup a pin as interrupt source and then call user defined callback function?

misterbee — Thu, 04 Aug 2022 12:36:14 GMT

I am using LPC 54113 MCU. I want to use the config tool. Suppose I have a pin PIO0_1 initially at high. When it goes low, I want it to raise interrupt and then call my defined callback function say my_callback().

How can I achieve this? How should I do the configuration?

Hello,

I suggest downloading the SDK of the LPCxpresso54114 and reviewing the example lpcxpresso54114_pint_pin_interrupt then you can port it to your target.

Best regards,
