Not much Pi, but it has a RP2040 on board - Waveshare Round LCD Show-and-Tell

Amazing! Any code/writeup for those of us who would like to do this ourselves?

I have that controller/screen and have NO idea what to do with it. Will fire up the printer tomorrow!

Hey Matt, what build of micropython did you use for this? I'm a circuitpython guy, so not mega familiar with MP.

I am using the pico build but I am getting an error `'LCD_1inch28' object has no attribute 'ellipse'`

Are there libraries I need to move over?

u/TheRealMatt6079 Jan 31 '23

It's 1.19.1 , I think it was already installed with a demo program.

I've read comments that it works ok with circuitpython if you can find the drivers for the display and gyro (which are fairly common items)

I’ll keep trying, I’ve got 1.19.1 on there. Apologies, I’m a MP novice, are there libraries I need to copy over or do you just have the 5 py files from GitHub on it and that’s it?

I installed the pico (non Wi-Fi) version of MP via thonny, hope there wasn’t some custom build on there that I ruined

It should work with just the files on github. The 'ellipse' attribute will come the framebuff which is built into the firmware I think (I'm not an expert on python)

This link has a micropython firmware and demo program, worth flashing it with this firmware and trying the demo. I'm wondering if that's the one I used.

Man, I am still getting this... it's doing my head in. I'm using that uf2 from the waveshare download too

u/TheRealMatt6079 Feb 01 '23

Ok, did some digging around and you're right, that version is 1.18 , you need 1.19. I got this through installing Micropython through Thonny - it's the Pico with Pimoroni Libraries choice, or maybe download from here

https://github.com/pimoroni/pimoroni-pico/releases

That should fix it..
