gpiote for quadrature counter

Hi,

I want to connect a rotary encoder. So I have 2 pins of the nrf51822 connected to the encoder and I have to check which one change first to increase or decrease the position. The gpiote callback doesn't work for me because it may be called once with the 2 events. Can I change the behaviour so that it is called on every changes ?

Thanks, Benoit

Sorry, I should have first asked you this, are you using quadrature decoder on the Nordic chip?

I directly connect the encoder to the nrf51822. Your answer was correct (I suppose). I just have to find how to implement it (I haven't work with ppi yet.)

you can find a lot of examples for that. Try out with GPIOTE and PPI examples and play around. If you have any problems then let me know.
