Rust/RTIC on PineTime

Target MCU: nRF52832 (xxAA)

Current status: PoC

What works:

• Bare-metal Rust with nrf52-hal
• RTIC for concurrency
• embedded-graphics for drawing onto the LCD
• Detect button presses
• Cycle through backlight brightness levels using button
• Show battery charge status and voltage
• Send BLE advertisement frames using the pure-Rust rubble stack

Planned:

• A simple watch interface
• Support for the step counter
• Better Bluetooth support
