Raw Blame History

TODOs

  • Bug: sdcard file reading fails (due to A:/ prefix?)
  • Publish firmwares with upload tool
  • Bug: When closing a top level app, there's often an error "can't stop root app"
  • Bug: I2C Scanner is on M5Stack devices is broken
  • Create more unit tests for tactility-core and tactility (PC-only for now)
  • WiFi on-at-boot should be a setting in its app
  • Create app to edit WiFi settings (e.g. "forget" and "auto-connect" option)
  • Show a warning screen if firmware encryption or secure boot are off when saving WiFi credentials.
  • Show a warning screen when a user plugs in the SD card on a device that only supports mounting at boot.
  • T-Deck has random sdcard SPI crashes due to sharing bus with screen SPI: make it use the LVGL lock for sdcard operations?
  • Check service/app id on registration to see if it is a duplicate id
  • Fix screenshot app on ESP32: it currently blocks when allocating memory
  • Localisation of texts
  • Portrait support for GPIO app
  • App lifecycle docs mention on_create/on_destroy but app lifecycle is on_start/on_stop
  • Explore LVGL9's FreeRTOS functionality
  • Explore LVGL9's ILI93414 driver for 2.4" Yellow Board
  • Bug: in LVGL9 with M5Core2, crash when bottom item is clicked without scrolling first
  • Replace M5Unified and M5GFX with custom drivers (so we can fix the Core2 SD card mounting bug, and so we regain some firmware space)
  • Commit fix to esp_lvgl_port to have esp_lvgl_port_disp.c user driver_data instead of user_data
  • Wifi bug: when pressing disconnect while between WIFI_EVENT_STA_START and IP_EVENT_STA_GOT_IP, then auto-connect becomes activate again.

Core Ideas

  • Support for displays with different DPI. Consider the layer-based system like on Android.
  • If present, use LED to show boot status
  • 2 wire speaker support
  • tt::app::start() and similar functions as proxies for Loader app start/stop/etc.
  • Wi-Fi using dispatcher to dispatch its main functionality to the dedicated Wi-Fi CPU core (to avoid main loop hack)

App Ideas

  • System logger
  • Add FreeRTOS task manager functionality to System Info app
  • BlueTooth keyboard app
  • Chip 8 emulator
  • BadUSB (in December 2024, TinyUSB has a bug where uninstalling and re-installing the driver fails)
  • Discord bot
  • IR transceiver app
  • GPS app
  • Investigate CSI https://stevenmhernandez.github.io/ESP32-CSI-Tool/
