I've just started playing with one of these - and this works well, I'm running over the Bluetooth serial console, and the upload as uf2 is nice and fast.
I've connected it with a Seeed Round display before I dig too far, I wondered if anyone else had used this combo already.
I got (slightly) excited when I saw that the screen controller GC9A01 was in the codebase, but (I think) it's only compiled into the jswrap_bangle.c file and not available to a base Espruino build as a js module, and I couldn't see a compatible module already to use.
I did briefly try a tweaked bangle build, but unsurprisingly, that just created a screen of random garbage and appeared to freeze on boot so decided to leave that for now, although I think that might be just because I'm still using the AdaFruit uf2 bootloader and I should switch to the full bangle build.
So, before I go any further, just wanted to ask/see if anyone had done this combination already - I assume I just need to create a new js module probably based on https://www.espruino.com/modules/ST7789.js
I was planning on printing a custom case and hooking up two buttons to the NFC pins so I think this would work pretty well with a bangle build.
