If you are not sure about the quality of your harware (IJK,PASE interface, compatible controller, rusted microswitches?), this little code will show the state of these peripherals.
You can test:
Old and new IJK interface
PASE interface (I tried only with a reversible Stingy one)
Stingy (2nd fire button)
I didn't try with the Egoist interface, it should be compatible.
