Hi, the header is part of the ML_SynthTools -> https://github.com/marcel-licence/ML_SynthTools
I tried to made a little guide: https://youtu.be/c7TL8jcrnzs

Thank you! I wasn't aware the board definitions were integrated into the ML_SynthTools library.

I have another error that fails during the linking process maybe you can shed some light as to why.

I guess you tried to use DISPLAY_160x80_ENABLED. I tested the code the last time only without DISPLAY_160x80_ENABLED.

A quick fix would be to replace:

extern float delayToMix;
extern float delayInLvl;
extern uint32_t delayLen;
extern float delayFeedback;

by

float delayToMix = 0;
float delayInLvl = 0;
uint32_t delayLen = 0;
float delayFeedback = 0;

in screens.ino.

The display implementation is highly experimental.
