awesome

Is this for the version with a display or without? For the display it'd be great to init the display in board_init like the pygamer does.

[netroy]

@tannewt I've only tested this with the one with the display.
You can get a build from the CI artifacts, and try out the example I linked in the description.

[tannewt]

@netroy Ok, that's fine! Let's add _display to the end of the board ID to make that clear. It'd be nice to include the display init in board_init too. Want to give that a try? I think the pygamer_advanced has ST7789 init code in it.

[netroy]

@tannewt sure. but, lilygo_ttgo_t8_esp32s2_display sounds a bit mouthful. should I shorten the board name to lilygo_t8_display instead?

[tannewt]

@netroy sure! fine with me

@netroy there is another T8 board (with and without display) from LilyGo, but with ESP32 instead of ESP32S2...so I would keep ESP32S2 in the name of the board...

[skieast]

In my ports I had named them
lilygo_ttgo_t8_s2_st7789 (obv with display)
lilygo_ttgo_t8_s2 (without)

I was about to finish up my tinyuf2 changes for both boards but will wait a bit to see what the consensus is.

@tannewt updated and rebased. unfortunately I could not get the display_init code to work. I do have the code working in python. but, my C skills are just garbage.

@skieast I'll wait for your tinyuf2 PR. I suppose you already saw the PID for that.

[tannewt]

Thanks for the board name update! Just a couple other things.

Want to try and get it going or do it later? I can help point out differences if you push the C version and link to the Python version.

I'd like to try this, but in another PR, if that's okay.

[tannewt]

Yup, no problem! Thank you!

Thanks!

I've created a PR for the tinyuf2 support.
