- Wed Oct 25, 2017 2:10 pm #71214 Hello, I have tried a zilion combinations trying to address this LCD. Some refer to it as a ILI9163 board, others as a ST7735 board. Did someone manage to get it to work ? If so, please could you share your wiring diagram and a sample code ? The PIN layouts are very confuing to me (DC, A0, SDA, SCK, ...)

Many thanks for your help !

...so, it's not so easy

SDA (input data pin) -> must be connected to processor SPI MOSI line (Master Output Slave Input)
SCL (clock line) -> must be connected to processor SPI CLK line
DC (or sometimes A0) -> informs the display that the data or command is sent
CS (chip select) -> informs the display (when this line is LOW) that the information are directed to this device(in this case display)

If You are on arduino, please try this lib (it supports both ILI9163 and ST7735):

You can customize display type and pins configuration inside:

- Thu Oct 26, 2017 6:24 am #71228 What display are you referring to exactly?
Do you mean a 1.44" SPI TFT 128x128 pixel display?
Do you have a picture or a link to said display?

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
