I’m using the following pins for buttons on the Cerb40:
PB6-PB9, PA4, PA5, PC6, PC7
[em]All[/em] of them work fine as interrupt ports on the board individually. However, if I try to use them all at once I start getting different InterruptPorts not being able to create. Which ones depends on which order you try and create them.
I’ve managed to get 6 of the 8 working at the same time (PC6 & PC7 are the “problem pins”). I can also get the OLED, uSD, and Piezo going at the same time, no problems there.
I’m also seeing issues making PA6 & PA7 interrupts for the Tilt Sensor when trying to use all the pins. If I create just those interrupts alone they work fine.
It’s a little head-bangy.
G.U.S. save me! Any clues on how to get all this pins going at the same time?
