Hello,

I'm playing with MPR121 Capacitive touch sensor. Within the module, we shoulds be able to use up to height pins has a GPIO.

I did succeed to use it to decode 4 capacitives touch buttons, but never found a working example or library for using the MPR121 GPIO pins. I did read applications notes for it, but completly lost. First test to blink a LED on port 11.

Sorry, no code from me yet. All library and example that i found failed to load or compile. I don't want a solution, but get the knowledge of witch library is usable for the GPIO and how to use it.

Any help trully appreciated.

Martin
P.S. excuse my English, more fluent in French.

Hello Sterretje

Like many other library, they focus on the capacitive touch. I did not see info on how to use the GPIO functions.

Thanks for your input
