Work in progress

This is a custom firmware being developed for the LilyGo T-Deck, currently it is experimental & buggy.

I am terrible at C++ and still am trying to wrap my head around the language's logic, so most of this code has been shit out and written like a cowboy.

The project started out with as IRC bridge for Meshtastic over MQTT, just so I could say "we have IRC over radio", which later led to me modifying the official Meshtastic firmware to add extended features. I am deep in the rabbit hole of embedded development and am starting from scratch making this an entirely custom firmware.

This is being developed in my free time as a fun project. It is no where near being useful.

A compiled "release" will be done once I finish somoe fo the basic features, but feel free t compile this on your own to test it out!

Previews

Flashing the Firmware

Using VS Code

1. Add your user to the dialout group: sudo gpasswd -a YOURUSERNAME dialout (You will need to re-login after adding your user to the dialout group for it to take affect)
2. Install Visual Studio Code
3. Install the PlatformIO plugin
4. Hold down the trackball on the device, turn it on, and plug it in to the computer.
5. Press F1 and select PlatformIO: Build
6. Press F1 and select PlatformIO: Upload
7. Press the RST (reset) button ont he device.

Using ESP Tool

1. Take the firmware.bin file from the release page and download it. (no releases yet, we still building)
2. Install esptool: pip install esptool
3. Hold down the trackball on the device, turn it on, and plug it in to the computer.
4. Confirm the serial device in your /dev directory (Your device will likely be /dev/ttyAMC0 or /dev/ttyUSB0)
5. Flash the device: esptool.py --chip esp32-s3 --port /dev/ttyUSB0 --baud 115200 write_flash -z 0x1000 firmware.bin
6. Press the RST (reset) button ont he device.

Connecting to WiFi

The device will scan for WiFi networks on boot. Once the list is displayed, you can scroll up and down the list with the "u" key for UP and the "d" key for down.

Commands

Command	Description
/debug	Show hardware information
/me <message>	Send an ACTION message
/raw <data>	Send RAW data to the server

Debugging over Serial

1. Install screen: apt-get install screen (or whatever package manager you use)
2. Plug in your device via USB.
3. Turn the device on, and run: screen /dev/ttyAMC0 9600 (again, this can also be /dev/ttyUSB0)

• Syslog (All serial logs will be displayed here for on-device debugging)

Known issues

• Messages that exceed the screen width and wrap to the next line will throw off thje logic of calculating the max lines able to be displayed on the screen. Messages eventually go off screen.
• Input messages exceeding the screen width go off screen, and need to wrap and create a new input line, pushing up the backlog of messages.
• Some colors are not working when its only a background color or only contains a space
• Sometimes it will not connect to IRC even from reconnections, and you have to reboot and try again.
• Screen timeout can occur during an IRC reconnection and blck keyboard input
