The goal of this project is to build a firmware designed for the PineTime around FreeRTOS.
|
||||
It's coded using a mix of C and C++ : the NRF52-SDK and FreeRTOS are written in C, but I prefer to write my own code in C++.
|
||||
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 heartrate sensor and a vibrator.
|
||||
|
||||
Please **NOTE : for now, this project is in heavy development state**. Feel free to use it, contribute to it or fork it !
|
||||
The goal of this project is to design an open-source firmware for the Pinetime smartwatch :
|
||||
|
||||
This project is based on https://github.com/JF002/nrf52-baseproject.
|
||||
It's a CMake project that configure everything needed to build applications for the PineTime (https://wiki.pine64.org/index.php/PineTime).
|
||||
- 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.
|
||||
|
||||
I tested this project (compile only) with the following versions:
|
||||
##Overview
|
||||
|
||||
* gcc-arm-none-eabi-8-2019-q3-update (from https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
|
||||
* nRF5_SDK_15.3.0_59ac345 (from https://www.nordicsemi.com/Software-and-Tools/Software/nRF5-SDK)
|
||||
|

Here a quick list out of my head of things to do for this project:
|
||||
|
||||
- Improve BLE communication stability and reliability
|
||||

||||
- Add more functionalities : Alarm, chrono, 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 selfhosted and easy to reproduce).
|
||||
|
||||
**Note** : By default, the build configuration *Release* is applied. It means that the code is built with optimisations enabled (-O3). If you wanto to compile in *Debug* mode to ease debugging and step-by-step debugging, specify the CMake variable `CMAKE_BUILD_TYPE` in the CMake command line:
|
||||
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:
|
||||
|
||||
* Make
|
||||
```
|
||||
$ make -j pinetime-app
|
||||
```
|
||||
- [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, buils a MCUBoot based bootloader for the Pinetime, design a Flutter based companion app for smartphones and write a lot of articles about the Pinetime!
|
||||
|
||||
## How to program
|
||||
### Using make
|
||||
|
||||
* Erase
|
||||
|
||||
```
|
||||
$ make FLASH_ERASE
|
||||
```
|
||||
|
||||
* Flash application
|
||||
|
||||
```
|
||||
$ make FLASH_pinetime-app
|
||||
```
|
||||
|
||||
* For your information : list make targets :
|
||||
|
||||
```
|
||||
$ make help
|
||||
```
|
||||
|
||||
### Using GDB and a Black Magic Probe (BMP)
|
||||
You can use this procedure if you want to flash the firmware (from a release, for example) without having to build the project locally.
|
||||
|
||||
Enter the following command into GDB:
|
||||
|
||||
```
|
||||
target extended-remote /dev/ttyACM0
|
||||
monitor swdp_scan
|
||||
attach 1
|
||||
file ./pinetime-app-full.hex
|
||||
load
|
||||
run
|
||||
```
|
||||
|
||||
*Note* : Sometimes, I need to run this procedure 2 times : the first time, the screen stays blank, and the second time, it works. This is something I'll need to debug...
|
||||
|
||||
Example:
|
||||
```
|
||||
$ /home/jf/nrf52/gcc-arm-none-eabi-8-2019-q3-update/bin/arm-none-eabi-gdb
|
||||
|
||||
(gdb) target extended-remote /dev/ttyACM0
|
||||

|
||||
(gdb) monitor swdp_scan

|
||||

|
||||

|
||||

||||
|
||||

|
||||

|
||||

|
||||
(No debugging symbols found in ./pinetime-app-full.hex)
|
||||
(gdb) load
|
||||

|
||||

|
||||
Start address 0x0, load size 314200
|
||||
Transfer rate: 45 KB/sec, 969 bytes/write.
|
||||
```
|
||||
|
||||
## RTT
|
||||
|
||||
RTT is a feature from Segger's JLink devices that allows bidirectionnal communication between the debugger and the target.
|
||||
This feature can be used to get the logs from the embedded software on the development computer.
|
||||
|
||||
* Program the MCU with the code (see above)
|
||||
* Start JLinkExe
|
||||
|
||||
```
|
||||
$ JLinkExe -device nrf52 -if swd -speed 4000 -autoconnect 1
|
||||
```
|
||||
|
||||
* Start JLinkRTTClient
|
||||
|
||||
```
|
||||
$ JLinkRTTClient
|
||||
```
|
||||
|
||||
## Tools
|
||||
|
||||
- https://github.com/eliotstock/memory : display the memory usage (FLASH/RAM) using the .map file from GCC.
|
||||
|
||||
## BLE connection and time synchronization
|
||||
At runtime, BLE advertising is started. You can then use a smartphone or computer to connect and bond to your Pinetime.
|
||||
As soon as a device is bonded, Pinetime will look for a **CTS** server (**C**urrent **T**ime **S**ervice) on the connected device.
|
||||
|
||||
### Using Android and NRFConnect
|
||||
Here is how to do it with an Android smartphone running NRFConnect:
|
||||
|
||||
* Build and program the firmware on the Pinetime
|
||||
* Install NRFConnect (https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Connect-for-desktop)
|
||||
* Start NRFConnect and create a CTS server :
|
||||
- Tap the hamburger button on the top left and select "Configure GATT server"
|
||||
- Tap "Add service" on the bottom
|
||||
- Select server configuration "Current Time Service" and tap OK
|
||||
* Go back to the main screen and scan for BLE devices. A device called "PineTime" should appear
|
||||
* Tap the button "Connect" next to the PineTime device. It should connect to the PineTime and switch to a new tab.
|
||||
* If a CTS server is found, the Pinetime should update its time with the time provided by the server.
|
||||
|
||||
### Using Linux and bluetoothctl
|
||||
* Ensure that your bluetooth controller is enabled and working fine. I've tested this on a x86 Debian computer and on a RaspberryPi 3.
|
||||
* Run bluetoothctl as root : `sudo bluetoothctl`
|
||||
* Enter the following commands:
|
||||
* `scan on` and wait for you Pinetime to be detected. Note the BLE MAC address
|
||||
* `scan off'
|
||||
* `trust <MAC ADDRESS>`
|
||||
* `pair <MAC ADDRESS>`
|
||||
* Wait for some time, and the connection should be established.
|
||||
|
||||
**NOTE : ** The commands above establish a BLE connection between your PC, but the time synchronization and notifications won't work because there is not CTS or ANS server running. I'm currently working on an application that'll provide both of these servers.
|
||||
|
||||
### Troubleshooting
|
||||
If the connection cannot be established, or the time synchronization does not work, try the following steps.
|
||||
|
||||
On Android:
|
||||
* Disable and re-enable your bluetooth device
|
||||
* In NRFConnect, in the device tab corresponding to your pinetime, tap on the menu on the top left of the screen and select "Delete bond information".
|
||||
* Then re-try to bond/connect.
|
||||
|
||||
On Linux:
|
||||
* Reset the bluetooth device : `sudo hciconfig hci0 reset`
|
||||
* Restart the Bluetooth service : `sudo systemctl restart bluetooth.service`
|
||||
* In bluetootctl:
|
||||
* `remove <MAC ADDRESS>`
|
||||
* `trust <MAC ADDRESS>`
|
||||
* `pair <MAC ADDRESS>`
|
||||
|
||||
Note that the current firmware only advertise for the first 3 minutes. If you cannot connect after more than 3 minutes, try resetting the device (push the button and hold it for 7-10 seconds).
|
||||
*If you feel like you should appear on this list, just get in touch with me or submit a PR :)*

# 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.

# Build
|
||||
##Dependencies
|
||||
To build this project, you'll need:
|
||||
- A cross-compiler : [gcc-arm-none-eabi-8-2019-q3-update](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads/8-2019q3-update)
|
||||
- The NRF52 SDK 15.3.0 : [nRF5_SDK_15.3.0_59ac345](https://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v15.x.x/nRF5_SDK_15.3.0_59ac345.zip)
|
||||
- A reasonably recent version of CMake (I use 3.16.5)
|
||||
|
||||
##Build steps
|
||||
###Clone the repo
|
||||
```
|
||||
git clone https://github.com/JF002/Pinetime.git
|
||||
cd Pinetime
|
||||
mkdir build
|
||||
cd build
|
||||
```
|
||||
###Project generation using CMake
|
||||
CMake configures the project according to variables you specify the command line. The variables are:
|
||||
|
||||
Variable | Description | Example|
|
||||
----------|-------------|--------|
|
||||
**ARM_NONE_EABI_TOOLCHAIN_PATH**|path to the toolchain directory|`-DARM_NONE_EABI_TOOLCHAIN_PATH=/home/jf/nrf52/gcc-arm-none-eabi-9-2019-q4-major/`|
|
||||
**NRF5_SDK_PATH**|path to the NRF52 SDK|`-DNRF5_SDK_PATH=/home/jf/nrf52/Pinetime/sdk`|
|
||||
**USE_JLINK, USE_GDB_CLIENT and USE_OPENOCD**|Enable *JLink* mode, *GDB Client* (Black Magic Probe) mode or *OpenOCD* mode (set the one you want to use to `1`)|`-DUSE_JLINK=1`
|
||||
**CMAKE_BUILD_TYPE**| Build type (Release or Debug). Release is applied by default if this variable is not specified.|`-DCMAKE_BUILD_TYPE=Debug`
|
||||
**NRFJPROG**|Path to the NRFJProg executable. Used only if `USE_JLINK` is 1.|`-DNRFJPROG=/opt/nrfjprog/nrfjprog`
|
||||
**GDB_CLIENT_BIN_PATH**|Path to arm-none-eabi-gdb executable. Used only if `USE_GDB_CLIENT` is 1.|`-DGDB_CLIENT_BIN_PATH=/home/jf/nrf52/gcc-arm-none-eabi-9-2019-q4-major/bin/arm-none-eabi-gdb`
|
||||
**GDB_CLIENT_TARGET_REMOTE**|Target remote connection string. Used only if `USE_GDB_CLIENT` is 1.|`-DGDB_CLIENT_TARGET_REMOTE=/dev/ttyACM0`
|
||||
|
||||
|
||||
####CMake command line for JLink
|
||||
```
|
||||
cmake -DCMAKE_BUILD_TYPE=Debug -DARM_NONE_EABI_TOOLCHAIN_PATH=... -DNRF5_SDK_PATH=... -DUSE_JLINK=1 -DNRFJPROG=... ../
|
||||
```
|
||||
|
||||
####CMake command line for GDB Client (Black Magic Probe)
|
||||
```
|
||||
cmake -DARM_NONE_EABI_TOOLCHAIN_PATH=... -DNRF5_SDK_PATH=... -DUSE_GDB_CLIENT=1 -DGDB_CLIENT_BIN_PATH=... -DGDB_CLIENT_TARGET_REMOTE=... ../
|
||||
```
|
||||
|
||||
####CMake command line for OpenOCD
|
||||
```
|
||||
cmake -DARM_NONE_EABI_TOOLCHAIN_PATH=... -DNRF5_SDK_PATH=... -DUSE_OPENOCD=1 -DGDB_CLIENT_BIN_PATH=[optional] ../
|
||||
```
|
||||
|
||||
###Build the project
|
||||
During the project generation, CMake created the following targets:
|
||||
- FLASH_ERASE : mass erase the flash memory of the NRF52.
|
||||
- FLASH_pinetime-app : flash the firmware into the NRF52.
|
||||
- pinetime-app : build the standalone (without bootloader support) version of the firmware.
|
||||
- pinetime-mcuboot-app : build the firmware with the support of the bootloader (based on MCUBoot).
|
||||
- pinetime-graphics : small firmware that writes the boot graphics into the SPI flash.
|
||||
|
||||
If you just want to build the project and run it on the Pinetime, using *pinetime-app* is recommanded. See ???? for more info about bootloader support.
|
||||
|
||||
Build:
|
||||
```
|
||||
make -j pinetime-app
|
||||
```
|
||||
|
||||
List of files generated:
|
||||
Binary files are generated into the folder `src`:
|
||||
- **pinetime-app.bin, .hex and .out** : standalone firmware in bin, hex and out formats.
|
||||
- **pinetime-app.map** : map file
|
||||
- **pinetime-mcuboot-app.bin, .hex and .out** : firmware with bootloader support in bin, hex and out formats.
|
||||
- **pinetime-mcuboot-app.map** : map file
|
||||
- **pinetime-graphics.bin, .hex and .out** : firmware for the boot graphic in bin, hex and out formats.
|
||||
- **pinetime-graphics.map** : map file
|
||||
|
||||
###Program and run
|
||||
####Using CMake targets
|
||||
These target have been configured during the project generation by CMake according to the parameters you provided to the command line.
|
||||
|
||||
Mass erase:
|
||||
```
|
||||
make FLASH_ERASE
|
||||
```
|
||||
|
||||
Flash the application:
|
||||
```
|
||||
make FLASH_pinetime-app
|
||||
```
|
||||
|
||||

####JLink RTT
|
||||
RTT is a feature from Segger's JLink devices that allows bidirectionnal communication between the debugger and the target. This feature can be used to get the logs from the embedded software on the development computer.
|
||||
|
||||
- Program the MCU with the code (see above)
|
||||
- Start JLinkExe
|
||||
|
||||
```
|
||||
$ JLinkExe -device nrf52 -if swd -speed 4000 -autoconnect 1
|
||||
```
|
||||
|
||||
Start JLinkRTTClient
|
||||
```
|
||||
$ JLinkRTTClient
|
||||
```
|
||||
|
||||
