Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi-de-hi.

In the ST7735 Cfunction driver for the 170 series chips, it says there is a pin you have to assign for the 7735's A0 control, but my display has no such 'A0' line.

These are my LCD's.

I don't suppose that 'A0' is actually nerd-speak for a Register-Select or RS line, by any chance?

On the unpopulated header space at the other side of these LCD's, there is a RS pin for the TFT there. I don't suppose this is the A0 line is it?Edited by Grogster 2016-01-26
