Hi, i made this and i face a problem i cannot fix.
(looks like internal config of mmjoy is not "correct" - eeprom pb ? )
When i test all the buttons they work as expected.
but, when i launch VKB button tester some are lit. (as if they were configured as button inverted)
If i "short" the 74 it shows pysically up , but reported down.
if i short the 75 it "works" but on/off very fast (some ms ) even if i keep the button pressed.
If i change the config of timer1 , it lights the button 37 !!
Timer 2 add another button .. etc..
Looks really like the config memory if overflowing somewhere and informations are "misread" to translate and report button physical status to windows.
Any idea welcome.
Edit: Tested 20160818 upd1, tried with the firmware after exactly same behavior.
Edit : Tested with another Arduino not connected to my board. The behavior looks the same...
