gpio (the program), how to set an interrupt
#1
Hi forum,
I'm trying to interface the GPIO with two push buttons. I used the cli command gpio, now I'd like to set up an interrupt so the program is idle as long as the pin change is detected.

I can't get this working. I can read the state of the pin, but if I want to set edge or  wfi, the program will exit without waiting.

I hope someone got a bit of experience to share.

Correction:

I read the C source, and the wfi and edge are not supposed to work.... Seen from the usage:
Code:
$ gpio -h
gpio: Usage: gpio -v
       gpio -h
       gpio [-g|-1] [-x extension:params] ...
       gpio [-p] <read/write/wb> ...
       gpio <read/write/pwm/mode> ...
       gpio readall/reset
       gpio unexportall/exports
       gpio export/edge/unexport ...
       gpio pwmr <range>
       gpio pwmc <divider>
       gpio load spi/i2c
       gpio unload spi/i2c
       gpio i2cd/i2cdetect
