The thing is getting more and more complicated...

Yes, you are right. I took it for granted that this was taken care in the include file. Now it works OK with hard I2C also.

Next, how to import the 16x16 characters into the 5x7 library.

Can...

Just tested the new include you post and works with soft I2C as expected. But not on hardware I2C...

Merry Xmas to all.

here are the files I used to test the SSD1306 lcd.

The selection of pixel columns and lines is really slow process. Seems you cannot numerically define lines and columns. Just adding one...

OK, thanks.

Will order then a few to play with.

Can these LCD's show custom characters?

I have a request to make a display that will show chess pieces like this ♟️ -> A4.

Very nice! Congratulations for the conquer of the Usercommand. Never could find how to make use of it.

Ioannis

Nice work, thanks Richard for sharing.
