1.8" Adafruit ST7735 display shield on Arduino under FC7

[jadiflow]

Hello,

Has anyone used this Adafruit 1.8" display shield on an Arduino Uno within FC7? It is supposed to be compatible to the Matrix EBM001. I can't get it to respond but probably I don't have the connections property set up correct, as they are not all clear to me. Anybody use this successfully?

Hello Jan,

That display looks more like the EB043-00-2 display. Maybe try this component instead and see if the pin connections make more sense.

I believe the EBM001 display uses a ILI9163C display driver IC.

OK, yes that may be the case, the adafruit uses the ST7735R controller. I will try the EB043-002

The EB043-002 display component has 4 connections associated: Sclk, Cs, data/command and data. I understand the first 3 as they are also called out like that in the adafruit display. Am I to assume that the 'data' bit is what is also called MOSI?

One comment: if the program runs in the simulator, that only means that the correct code is generated for the display. It does not say anything whether the connections to the physical display are right or not, because FC doesn't know about the physical display. Correct?

... and why is it that there is no trace at all of that EB043-002 board on the Matrix website?? The only gLCD modules shown are EBM001 and EB084.

Edit: Google leads to EB043-00-1 data sheet on the Matrix website, but Matrix' search engine doesn't know it.

Can anybody confirm or otherwise that the EB043-002 is based on the ST7735R driver chip? If not, is there anything in the FC gLCD library that is based on the ST7735R?
