Example code for the T-Deck

[joshmarinacci]

I put together some example Rust no_std code for the Lilygo T-deck. It shows how to get the display running, use the keyboard and trackball, check the battery, and connect to wifi & download a file.

It uses the latest 1.0.0 beta, though I think the behavior of I2C may have changed slightly between beta0 and beta1.

I hope this helps any of you working with the T-deck and related boards.

It reminds me of the good old Blackberry mobile phone 😄

How long can this device run on battery (which battery) with screen on? and with screen off?

Awesome, thanks - probably this repo should get added to https://github.com/esp-rs/awesome-esp-rust

I've just updated the repo with better docs, upgraded esp-hal (to rc.0), and added examples for the touch screen, sd card, and getting device info like memory usage and chip name.

If anyone knows how to work with I2S I'd love some help on audio support. Just getting it to play a sine wave without DMA would be a huge help.

I was able to get the SD card working by looking at the Arduino example code from the LilyGo repo. It can list files on the card and read in a text file. Note that the SD card must be FAT formatted. ExFat doesn't seem to work.
