cd jebbatime
./scripts/jebbatime-install-deb-deps
./scripts/jebbatime-install-py-deps
```

### Python
Manually, install Python dependencies with `pip`.

```
pip3 install --user -r wasp/requirements.txt
pip3 install --user freetype-py
```

## Bullseye
Debian Bullseye (11) on ppc64le wants `rustc` to build/install `pip`
package `cryptography`.

```
./scripts/jebbatime-install-deb-deps
sudo apt -y install rustc
./scripts/jebbatime-install-py-deps
```

### Submodules
Some submodules are mirrored.

```
make submodules
# XXX grabs some source zips
make softdevice
```

### Compile
Build thang.

```
# Blow out, rinse, repeat. Should take less than a minute or so.
make mrproper
make clean BOARD=pinetime
make submodules
make all BOARD=pinetime

```
### Fonts
HOWTO add font.

```
cd tools/micropython-font-to-py

./font_to_py.py								\
	/usr/share/fonts/opentype/lobstertwo/LobsterTwo-Bold.otf	\
	--xmap 64							\
	--errchar 58							\
	--smallest 48							\
	--largest 58							\
	lobstertwobold64.py

mv lobstertwobold64.py ../../wasp/fonts/
```

# Setup
This assumes two devices, the sealed watch and the open developers watch.

```
mkdir ~/.config/
cp -p config/jebbatime.conf ~/.config/
# Adjust as needed.
vim ~/.config/jebbatime.conf
```

# Use
Basic scripts are in `scripts/`.

## Fork
jebbatime is a lesser fork of Daniel Thompson's Wasp-os.

* Same licenses.
* Renamed.
* Removed more than added.
* Removing bits not used on Pinetime.
* Removing bits not used by me.
* No step counter.
* No heart rate monitor.
* Etc.
* Not much useful added.
* Nice digital face font. Battery and BLE icon removed from main app.
