SSD1306 OLED (72x40) I2C display from scratch

don't see any reasons, why you can't write GLCD generated or any other software generated font into external EEPROM.

Nor do I , but I have never come anything to make a bin or hex file easily from the generated code

(which can't save file on windows 10-11)

mine works perfectly win 10 and 11 , make sure to add the .lcd extension to the file name when saving it otherwise it goes funny

Why not use it for font storage?

Because this thread will be followed with "how can I speed up my OLED display routines?".

The choice is obviously yours, but the 18F27Q43 has 128K of flash, 8K of ram, and runs at 64MHz.
The only downside is the hardware I2C peripheral isn't compatible with the old MSSP I2C, so you're stuck using PBP's software I2CWRITE/I2CREAD or rolling your own (which is not trivial for these new parts).
