Espruino on GeekMagic SmallTV?

[joakim]

Has anyone flashed Espruino on GeekMagic's SmallTV Ultra? It's a nifty little ESP32-12F device that's ridiculously cheap ($1) and cool looking. The ESPhome community has figured out the specs and pinout of the display and successfully flashed ESPhome. Is it feasible to make it run Espruino with the display and all?

Yes it's definitely possible. There's a port to ESP32 CYD that'd probably be a pretty good starting point - probably there only big change is making sure the LCD gets initialised properly

Thanks for the quick answer, Gordon! I have myself a weekend project 😁

Sorry, I was mistaken, it's not an ESP32, but ESP8266 (ESP-12F). I assume ESP8266_4MB would be the right starting point?

(SmallTV Pro uses ESP32-S3-WROOM, but costs 10× as much.)

Ahh - I'm sure I saw something more sensibly priced out there with ESP32 in.

There are some other really cool options too like https://www.aliexpress.com/item/1005006194839720.html

But yes, ESP8266_4MB would be a good start - you should still be able to do some pretty cool stuff with it!

@joakim That's a cute little device! Did you buy one? Did you even get started on putting espruino on it?

[joakim]

@Tobbe It is just as cute in real life :) The cheap Ultra doesn't have a USB to serial on the USB-C port, so an FTDI adapter is needed, and I can't find mine. So I haven't gotten that far yet, unfortunately. The more expensive versions use ESP32-S3 and can be flashed over the USB-C cable.

[Tobbe]

That's a bummer with the FTDI adapter! Hope you find it :) (Or spend the money to get the esp32 one)

[joakim]

Thanks! I think I'd rather spend the money on a new FTDI adapter, but I would go with the ESP32-S3 version if I was buying it again.
