# PineTime
|
||
> The PineTime is a free and open source smartwatch capable of running custom-built open operating systems. Some of the notable features include a heart rate monitor, a week-long battery as well as a capacitive touch IPS display that is legible in direct sunlight. It is a fully community driven side-project, which means that it will ultimately be up to the developers and end-users to determine when they deem the PineTime ready to ship.
|
||
|
||
> We envision the PineTime as a companion for not only your PinePhone but also for your favorite devices — any phone, tablet, or even PC.
|

|
||
|
||
The **Pinetime** smartwatch is built around the NRF52832 MCU (512KB Flash, 64KB RAM), a 240*240 LCD display driven by the ST7789 controller, an accelerometer, a heart rate sensor, and a vibration motor.
|
||
|
||
The goal of this project is to design an open-source firmware for the Pinetime smartwatch :
|
||
|
||
- Code written in **modern C++**;
|
||
- Build system based on **CMake**;
|
||
- Based on **[FreeRTOS 10.0.0](https://freertos.org)** real-time OS.
|
||
- Using **[LittleVGL/LVGL 6.1.2](https://lvgl.io/)** as UI library...
|
||
- ... and **[NimBLE 1.3.0](https://github.com/apache/mynewt-nimble)** as BLE stack.
|
||
|
||
## Overview
|
||
|
||
|
||
|
||
As of now, here is the list of achievements of this project:
|
||
|
||
- Fast and optimized LCD driver
|
||
- BLE communication
|
||
- Rich user interface via display, touch panel and push button
|
||
- Time synchronization via BLE
|
||
- Notification via BLE
|
||
- Multiple 'apps':
|
||
* Clock (displays the date, time, battery level, ble connection status, heart rate and step count)
|
||
* Heart rate
|
||
* Motion
|
||
* System info (displays various info: BLE MAC, build date/time, uptime, version, ...)
|
||
* Brightness (allows the user to configure the brightness of the display)
|
||
- Supported by 2 companion apps (developments ongoing):
|
||
* [Gadgetbridge](https://codeberg.org/Freeyourgadget/Gadgetbridge/src/branch/pinetime-jf) (on Android)
|
||
* [Amazfish](https://openrepos.net/content/piggz/amazfish) (on SailfishOS)
|
||
- **[Experimental]** OTA (Over-the-air) update via BLE
|
||
- **[Experimental]** Bootloader based on [MCUBoot](https://juullabs-oss.github.io/mcuboot/)

## TODO - contribute
|
||
|
||
This project is far from being finished, and there are still a lot of things to do for this project to become a firmware usable by the general public.
|
||
|
||
Here a quick list out of my head of things to do for this project:
|
||
|
||
- Improve BLE communication stability and reliability
|
||
- Improve OTA and MCUBoot bootloader
|
||
- Add more functionalities : Alarm, chronometer, configuration, activities, heart rate logging, games,...
|
||
- Add more BLE functionalities : call notifications, agenda, configuration, data logging,...
|
||
- Measure power consumption and improve battery life
|
||
- Improve documentation, take better pictures and video than mine
|
||
- Improve the UI
|
||
- Create companion app for multiple OSes (Linux, Android, IoS) and platforms (desktop, ARM, mobile). Do not forget the other devices from Pine64 like [the Pinephone](https://www.pine64.org/pinephone/) and the [Pinebook Pro](https://www.pine64.org/pinebook-pro/).
|
||
- Design a simple CI (preferably self-hosted and easy to reproduce).
|
||
|
||
Do not hesitate to clone/fork the code, hack it and create pull-requests. I'll do my best to review and merge them :)

## Credits
|
||
I’m not working alone on this project. First, many people create PR for this projects. Then, there is the whole #pinetime community : a lot of people all around the world who are hacking, searching, experimenting and programming the Pinetime. We exchange our ideas, experiments and code in the chat rooms and forums.
|
||
|
||
Here are some people I would like to highlight:
|
||
|
||
- [Atc1441](https://github.com/atc1441/) : He works on an Arduino based firmware for the Pinetime and many other smartwatches based on similar hardware. He was of great help when I was implementing support for the BMA421 motion sensor and I²C driver.
|
||
- [Koen](https://github.com/bosmoment) : He’s working on a firmware based on RiotOS. He integrated similar libs than me : NimBLE, LittleVGL,… His help was invaluable too!
|
||
- [Lup Yuen Lee](https://github.com/lupyuen) : He is everywhere: he works on a Rust firmware, builds a MCUBoot based bootloader for the Pinetime, designs a Flutter based companion app for smartphones and writes a lot of articles about the Pinetime!
