Hi

Since there is no GPIO button on FRDM-KL25Z board, please refer the 'gpio_input_interrupt' demo in SDK_2.2_FRDM-KL26Z.

(my apologies if it is against the forum rules to reply to such an old thread)

I've stumbled upon this thread when looking for my solutions to the problem described in the most recent thread I posted. I followed your instructions and downloaded the SDK archive, but the input_interrupt example seems to be absent from the archive. Has it been removed? If so, is there somewhere else I can download it?
