PebbleOS can run under a custom QEMU version shipped with the PebbleOS SDK.
./waf configure --board $BOARD
./waf build
where $BOARD is any of the qemu_* boards:
qemu_emeryqemu_flintqemu_gabbroQEMU boards target a specific platform, e.g. qemu_emery targets the Emery platform, which is the platform used by Pebble Time 2.
./waf qemu
The launched QEMU exposes:
-monitor stdio)-monitor unix:build/qemu-mon.sock)localhost:12345 (console) and localhost:12344 (pebble-tool)UART1 output is also captured to build/uart1.log.
./waf console
Requires QEMU to be running. Uses the TCP serial port to connect to the QEMU console, and provides a prompt for sending commands and receiving responses.
./waf screenshot # defaults to build/screenshot.png
./waf screenshot --screenshot-output /tmp/foo.png
Requires QEMU to be running. Uses the programmatic socket monitor to capture a screenshot of the QEMU display and save it to disk. Useful to validate or iterate on UI changes.
Keyboard input is captured by QEMU, so you can interact with the PebbleOS UI.
Keys can also be send programmatically over the socket monitor using the sendkey command.
They key mapping is:
| QEMU key | PebbleOS key |
|---|---|
left | back |
right | select |
up | up |
down | down |
