PineTime

• Master Build

• developLite Build

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.

PinetimeLite

This project is a fork of Infinitime

The purpose of PinetimeLite is to build firmware for Pinetime that is lightweight and maximizes battery life. The available features are :

• Quick settings to change the backlight, notification vibration and flash light
• Charging notification
• Low battery alert
• Notifications, with app identification
• Incoming call notification
• Backlight timeout config
• Screen wake up on double tap, single tap or Wrist wake up
• Screen sleep on double tap ( in any clock face )
• Multi watch faces ( 8 )
• Firmware update, now with high-speed transfer mode.
• Settings saved to external flash
• External resources, images and icons, are now in the external flash
• Weather app
• Step counter
• Sample app to show the accelerometer ( this app my not be included in future releases )

The 0.3.0 version removes the compatibility with Nordic DFU to update the firmware.

Companion app (development is in progress):

• Gadgetbridge (on Android)
• PinetimeLiteApp (on web browser) Compatible with version 0.3.0, it is possible with this application to set the clock, update resources and firmware.

Build PinetimeLite

I recommend build the project using Docker

This option can be used in Linux and Windows

Build the project with Docker

Dependencies to build this project, you'll need:

• A cross-compiler : ARM-GCC (9-2020-q2-update)
• The NRF52 SDK 15.3.0 : nRF-SDK v15.3.0
• A reasonably recent version of CMake (> 3.16)

$ git clone --recurse-submodules https://github.com/joaquimorg/PinetimeLite.git
$ mkdir build
$ cd build

Config

$ cmake -DCMAKE_BUILD_TYPE=Release -DARM_NONE_EABI_TOOLCHAIN_PATH=/usr -DNRF5_SDK_PATH=/mnt/d/Work/PineTime/nRF5_SDK_15.3.0_59ac345 -DUSE_OPENOCD=1 ../

More detail information where Build the project

regular build

$ make -j pinetime-lite

mcboot build

$ make -j pinetime-mcuboot-lite

Using Windows WSL2 and STLINK V2 to Build and Upload via OpenODC

In Windows :

• Install Docker in Windows
• Download xpack-openocd-0.10.0-15
• Configure Openocd to allow remote connections from WSL2 to do this, in the bin folder create a .bat file with this :

  openocd.exe -s ..\scripts\ -f interface\stlink.cfg -f target\nrf52.cfg -c "bindto 0.0.0.0"
  

  run the .bat file and verify if the connection to Pinetime is ok this is the result :

  Info : Listening on port 6666 for tcl connections
  Info : Listening on port 4444 for telnet connections
  Info : clock speed 1000 kHz
  Info : STLINK V2J29S7 (API v2) VID:PID 0483:3748
  Info : Target voltage: 3.226772
  Info : nrf52.cpu: hardware has 6 breakpoints, 4 watchpoints
  Info : starting gdb server for nrf52.cpu on 3333
  Info : Listening on port 3333 for gdb connections
  

  Leave the OpenOCD window open while programing the PineTime.

In WSL :

• Build the project with Docker

  cd <project_root> # e.g. cd ./work/PinetimeLite
  docker run --rm -it -v $(pwd):/sources pinetime-build
  

• Next, this is only for the first time :

  • Find you computer IP, the connection between WSL and windows can only be done via IP
  • Install the "GNU Arm Embedded Toolchain"

• Programing the bootloader, do this only if necessary, the comand will erase all memory in the Pinetime

  arm-none-eabi-gdb --batch \
  -ex="target extended-remote XXX.XXX.XXX.XXX:3333" \
  -ex "monitor halt" \
  -ex "monitor nrf5 mass_erase" \
  -ex "monitor program <project_root>/build/output/bootloader.bin 0x00000000"
  

  replace <project_root> with the full path to your project. replace XXX.XXX.XXX.XXX with you computer IP.

• Programing the Pinetime-Lite to Pinetime

  arm-none-eabi-gdb --batch \
  -ex="target extended-remote XXX.XXX.XXX.XXX:3333" \
  -ex "monitor program <project_root>/build/output/pinetime-lite-0.1.0.bin 0x00008000" \
  -ex "monitor reset"
  

  replace <project_root> with the full path to your project. replace XXX.XXX.XXX.XXX with you computer IP.

• In this fork you have 3 shell script to automate this steps

  • bdfu.sh - bilds with docker
  • p.sh - programs the Pinetime-Lite via OpenOCD
  • pboot.sh - clean the internal storage and programs the bootloader
