# Roadmap
## M1: Dumb watch feature parity
The focus for M1 is to get WASP both to meet feature parity with a dumb
watch and to have a bootloader and watchdog strategy that is robust enough
to allow a PineTime case to be confidently glued shut.
### Bootloader
* [X] Basic board ports (PineTime, DS-D6, 96Boards Nitrogen)
* [X] OTA application update
* [X] Enable watchdog before starting the application
* [X] Splash screen
* [X] Ignore start button for first few seconds
### MicroPython
* [X] Basic board ports (PineTime, DS-D6, 96Boards Nitrogen)
* [X] Long press reset (conditional feeding of the watchdog)
- [X] Feed dog from REPL polling loop
- [X] Feed dog from a tick interrupt
### WASP
* [X] Display driver
- [X] Display initialization
- [X] Bitmap blitting
- [X] RLE coder and decoder
- [X] Optimized RLE inner loops
* [X] Backlight driver
* [X] Button driver (polling)
* [X] Battery/charger driver
* [X] Simple clock and battery level application
* [X] Basic (WFI) power saving
* [X] Implement simple RTC for nrf52
## M2: Great developer experience
The focus for M2 is to make development faster and easier by providing
a file system and file transfer code. This allows much faster
development cycles compared to full downloads of frozen modules.
Additionally support for multiple event-driven applications will be
added during M2 to further help developers by providing example
applications.
### Bootloader
* [X] OTA bootloader update
* [X] RTC time measurement whilst in bootloader
### MicroPython
* [X] SPI FLASH driver
* [X] Enable LittleFS on SPI FLASH (at boot)
* [X] BLE file transfer
### WASP
* [X] Add dd/mm/yyyy support to RTC
* [X] Button driver (interrupt based)
* [X] Touch sensor driver
* [X] Event driven application framework
* [X] Stopwatch app
* [X] Settings app
* [X] PC-hosted simulation platform
* [O] Documentation
- [X] Sphinx framework and integration with github.io
- [X] Document bootloader protocols
- [X] Application writer's guide
- [ ] Write full docstring documentation for all WASP components
* [X] Application Launcher
* [X] Debug notifications
* [o] Multi-colour RLE images
- [X] Optimized "2-bit" RLE encoder and decoder
- [ ] Logarithmic RBG332 <-> RGB56516bit color space conversion
## M3: Smartwatch
At M3 we start to build out full fitness tracking and notification
functionality.
### Bootloader
* [ ] Stay in bootloader after battery run down
* [ ] Implement power off support (no splash screen)
### Micropython
* [ ] Use SoftDevice sleep logic
* [ ] Automatically enter SPI flash power saving mode
### WASP
* [ ] Enable heart rate sensor
- [ ] HRS3300 driver
- [ ] HRS data post-processing
- [ ] Heart rate counter app
* [ ] Notifications
- [ ] BLE notification protocol
- [ ] Notification popups
- [ ] Notification app (show notification history)
- [ ] Find a recommended Android app
* [ ] Step counting
- [ ] BMA421 driver
- [ ] Step counter app
