# Mac(intosh) mini

## Build Instruction
- Print the outer shell.
  - PLA, 0.2 mm, 180 ℃ (See also [./openscad/README.md](./openscad/README.md))
  - `macintosh-mini-part-a.stl` ([stl](./openscad/macintosh-mini-part-a.stl))
  - `macintosh-mini-part-b.stl` ([stl](./openscad/macintosh-mini-part-b.stl))

- Setup your Orange Pi Zero Plus 2 (H3)
  - Install Armbian Bionic. https://www.armbian.com/orange-pi-zero-plus-2-h3/
  - Then SSH into the device.
```bash
$ sudo apt install -y git tightvncserver

# Install Node.js
$ git clone https://github.com/tj/n /tmp/n && cd /tmp/n && sudo make install
$ sudo n v10

# Install https://github.com/xpertsavenue/WiringOP-Zero
$ cd ~/
$ git clone https://github.com/xpertsavenue/WiringOP-Zero
## Please refer to https://github.com/xpertsavenue/WiringOP-Zero

# Enable SPI1 interface
$ sudo vi /boot/armbianEnv.txt # or use armbian-config
! overlays=spi-spidev analog-codec usbhost2 usbhost3
+ param_spidev_spi_bus=1

# Setup vncserver
$ mkdir ~/.vnc
$ vncpasswd ~/.vnc/passwd

# Install the dependencies & config files
$ git clone https://github.com/likeablob/macmini ~/macmini
$ cd ~/macmini
$ sudo ./install.sh

# Copy your assets
$ cp /path/to/vmac.rom ~/macmini/minivmac/vMac.ROM # Mini vMac ROM file
$ cp /path/to/vmac.dsk ~/macmini/minivmac/system.dsk # Mini vMac disk file
$ cp /path/to/.basilisk_ii_prefs ~/.basilisk_ii_prefs # Basilisk II config file
$ cp /path/to/macboot.wav ~/macmini/macboot.wav # Boot sound (optional)

# Reboot to apply the settings
$ sudo reboot now

# Select LineOut as the default sink
$ pacmd list-sinks | grep -e 'name:' -e 'index:'
  index: 0
	  name: <alsa_output.platform-1c22c00.codec.analog-mono> # LineOut
* index: 1
	  name: <alsa_output.platform-soc_sound.stereo-fallback> # HDMI
$ pactl set-default-sink 0 # or use `DISPLAY=:1 pavucontrol` and `alsamixer` to adjust volume
```

## Basic Concepts
1. At system boot, [`fbtft_device`](./config/fbtft.conf) kernel module is loaded and it initializes the LCD as `/dev/fb0`.
2. `nodm` starts an X session and `~/.xinitrc` get executed.
3. `~/.xinitrc` launchs `matchbox-window-manager` and `~/macmini/switcher/*js`.
4. `~/macmini/switcher/index.js` reads the scripts [`~/macmini/switcher/sh.d/*sh`](./switcher/sh.d/) and spawns them one by one when there is a HTTP GET request at `localhost:5501/`.
5. `~/macmini/switcher/gpio-reader.js` watchs the push SW at GPIO7(PA06) and send a request to `localhost:5501/`.

### How does the low-res LCD(320x240) handle 512x384 resolution?
Internally `tightvncserver` and `ssvncviewer` are used to scale the display.
- e.g. [`1_large_minimac.sh`](./switcher/sh.d/1_large_minimac.sh) launches: 
  -  `tightvncserver` to create a virtual display (512x384) at `DISPLAY=:1` (`:5901`)
  -  `minivmac` in `DISPLAY:1`
  -  `ssvncviewer -scale 0.625` in `DISPLAY:0` (By the `-scale` option, low-res LED get upscaled)
