Hello guys,
I have been having issues with a project I'm working on. It's a USB midi controller with a i2c LCD.
I am using a pro micro board with the atmega32u4.
Everything was working great until i added some features:
- First: a save option that writes all the settings on the 32u4's eeprom.
- Second: the USB midi feature.
Everything regarding the menu system is working fine but when i upload the code with the eeprom library and code the controls don't respond anymore, same with the MIDIUSB.
The LCD just shows the first menu and that's it, the push buttons don't work.
I added a few serial prints to check if it was reaching the main loop, when i open the serial monitor things start working again.
If i comment out the eeprom and USB code the rest of the code works just fine.

I uploaded the platformIO project in a zipfile.

This is the Arduino forum, not that platformIO forum.

I guess you run out of memory. Your bank definitions need about a quarter of the available memory. You don't use the F() macro. Your sprintf calls should all be replaced by snprintf calls.
