Warning

This repository only represents the state of my own T-Watch. I will implement some apps that are very specific for my needs and will also disabled apps that I personally don't need. Maybe you find something interesting and maybe I'll create a PR for some apps I might create in the future, but currently nothing concrete is planned.

My-TTGO-Watch

A GUI named hedge for smartwatch like devices based on ESP32. Currently support for T-Watch2020 (V1,V2,V3), T-Watch2021 (V1 and V2, no ota-updates), M5Paper, M5Core2, WT32-SC01 and native Linux support for testing.

• Time synchronization via BLE

• Notification via BLE

• Step counting

• Wake-up on wrist rotation

• Quick actions:

  • WiFi
  • Bluetooth
  • GPS
  • Luminosity
  • Sound volume

• Multiple watch faces:

  • Embedded (digital)
  • Community based watchfaces

• Multiple 'apps':

  • Music (control the playback of the music on your phone)

Install

Clone this repository and open it with platformIO. Select the right env and then build and upload. Or follow the great step by step tutorial from ShotokuTech.

Please check out https://github.com/sharandac/My-TTGO-Watch/blob/709ed0c5863435aa966c1d6f44552ddc0909a57c/src/hardware/wifictl.cpp#L256-L261 to setup your wifi when wps or input via display is not possible.

If you are interested in native Linux support, please install sdl2, curl and mosquitto dev lib and change the env to emulator_* in platformIO.

sudo apt-get install libsdl2-dev libcurl4-gnutls-dev libmosquitto-dev build-essential

Known issues

• the webserver crashes the ESP32 really often
• the battery indicator is not accurate, rather a problem with the power management unit ( axp202 )

Development on the Windows platform

The development tools have a known issue with the size of the project on Windows platforms. When the program is built you may receive the following error:

xtensa-esp32-elf-g++: error: CreateProcess: No such file or directory
*** [.pio\build\t-watch2020-v1\firmware.elf] Error 1

This issue has not been seen on Linux or other platforms. This is a linker issue and can be fixed by removing apps. To remove unneeded apps you can simply delete the appropriate directory in /src/app. Then simply recompile. App can be added in the same way. But note that the app must support autocall_function . This allows the automatic integration of apps without touching the rest of the code ( the magic behind autocall_function ).

Since each app includes a different set of files, you may need to delete several apps to reduce it small enough for the Windows build.
