Hello,
I installed an debian image on a a20 board and I would like to know if it's possible to use the buttons normally used for Android (V+,V-,Home,etc...).
Refering to the official site : https://www.olimex.com/wiki/A20-OLinuXino-MICRO#Linux
pyA20 is used to control GPIO,I2C and SPI.
I check the board layout (https://www.olimex.com/wiki/A20-OLinuXino-MICRO) but the buttons android are only referenced by their functions. Do you have any ideas about how to detect an input from theses buttons on debian image ?
Regards
cat /dev/input/event1 gives reports on power button press, I think it (or event0/event2) will report also on other buttons, but currently my card is enclosed into box and I cant verify any button except power.
In order to parse this in C application - you should read from that device such structures: http://stackoverflow.com/questions/16695432/input-event-structure-description-from-linux-input-h (http://stackoverflow.com/questions/16695432/input-event-structure-description-from-linux-input-h)
Thank you very much, I will check the events, once I have the card.
