Buttons do NOT work.. solution :)

[gilmod714]

First off, Thank you so much Acemi for this wonderful solution .. it's a good project and Great work on the code too! -- it is basically a poor man's GOTEK :)

This project worked GREAT for me because I already had a failed Gotek device/enclosure. (it was a bad STM32 chip and replacing it was costly) .. So your design was perfect to renovate that old enclosure .. Only issue I had was, the buttons did not work at first (the first 2 buttons worked , but the others did not) .. serial debug showed activity ok though

SOLUTION:
So after some digging and looking at your code .. I figured it was some sort of a timing issue in the ladder of buttons .. I ended up changing the ADCVAL in "ADCButton.cpp" and recompiled the code (see attached screen shot) .. (also note: to recompile nano or nano-copy properly you need to add -b 57600 to avrdude .. add to make-file or do manually)

It worked great after that .. I also removed "Eject", just removed the button and kept the resistor.. inserting a new IMG replaces the old one anyways and the Gotek case had room for only 4 buttons crunched in the front on a perf PCB ;) ..

Just posting this to help someone who have the same issue with the buttons ..

Photos ..

The simplified schematic (for my build) ..

Thanks, I plan to mention this in readme
