Hi guys
I have tried to pilot OLED screen from Basic ESP. it works perfect with the 128x64 screen.
I also tried with the 128x32, but this one is seen as a 128x64 and so the draw is not great.

if you can add the support of this screen would be nice.

thanks

This is actually not the fault of the library (I'm using Arduino BTW), but of the board: the I2C 128x32 OLED is actually (in hardware) a 128x64 display where only the odd (or even, can't remember) rows are used.

The one I'm talking about is the one on the far right.

So for the row (Y-axis) positions in your code, you'll have to double everything.
Note that this is also true for fonts: they will look very odd (chopped off tops or bottoms) when not taking into account the missing in-between lines.

It is perfectly doable, but can be a pain to get it right.

Thanks for giving the guy such an impressive response to his problem, QuickFix.

Thank you very much for this clear explanation.
so with the Basic interpreter I think the management can't be easily implemented.
not a huge issue to be honnest. it's yet fantastic to be able to use the square version of the oled screen !

I think for the font, nothing to do,
for the graphic, I'll try to use the only even or odd option to see if I can get a nice square or line !
