Hi Folks.
I have set up my raspberry pi 2B with Venus 2.66 and got it to display the gui on the 2.2" non touch screen hat built into my pi case, the one with six buttons and IR receiver.
In case anyone else is using this screen there is an overlay available for the 2.2" screen hat here-
https://github.com/raspberrypi/firmware/tree/master/boot/overlays. it is called pitft22.dtbo. ;-)
As it is not a touch screen I would like to use the six physical buttons on the hat to control my venus in a similar way to the CCGX. these are wired to GPIO pins on the pi hat. can anyone tell me how the CCGX buttons are wired to it's processor?
I have tried adding the gpio-key.dtbo to the venus overlays folder and editing the config file to run the overlay using "dtoverlay=gpio-key, gpio=24,active_low=1,gpio_pull=up, label=Down, keycode=108"
This should give me a down button on GPIO pin 24 but the button is not responding.
Any help appreciated.
Cheers.
Bob.
