Lying in a drawer
Waiting for my day to come
As a first experiment, we'll put to work a noname oled display (128x64, SH1106-based, I2C bus) which has the first two rows damaged. Wish I knew beforehand how fragile these things are (don't even stare at the two glass corners opposed to the connector or they will break).
Quite a rollercoaster - TinyWireM not working well, U8x8 consumes too much memory and has it's own wire code... so, wrote another version that draws pixels and lines and has a minimal oled driver - attiny85-sh1106-clock-using-drawline
