“WaveShare 1.8inch LCD Display Module for Raspberry Pi Pico, 65K Colours, 160×128, SPI
I’ve been experimenting with this inexpensive display using the supplied MicroPython driver code to program it. Unusually it is embedded in the demonstration code rather than as a separate library.
It is not working quite as I expected. The stated resolution is 160 pixels wide – normally this would be 0-159, and 128 pixels high – normally 0-127. With the top left corner at (0,0)
I have found the corner pixels to be at coordinates:
(1,1) top left
(1,128) bottom left
(159,1) top right
(159,128) bottom right
The normal origin of a display (0,0) does not display a pixel and there are only 159 pixels on a line.
So, the resolution is 159 pixels wide and 128 pixels high with the mathematical origin off the display screen. Rather unusual but it works!
The colour is RGB 5-6-5 with 0 – 31 brightness levels for Red and Blue, but 0 - 63 for Green. I’ve written an Instructable to help you get to grips with the board and it provides a video of its capabilities. You can find it here:

A great value display, once you understand its differences. It usefully only connects to the minimum of pins it needs to work, leaving the rest for the user’s project.
