|
|
Protovac is software for an old dumb terminal CRT screen that's used to display
|
|
random info about Protospace. There's a few interactive features like sending
|
|
messages to a huge marquee LED sign and performing calculations.

## Development Setup
|
|
|
|
For developing on your own Ubuntu / Debian machine:
|
|
|
|
```
|
|
$ sudo apt update
|
|
$ sudo apt install python3 python3-dev python3-pip python3-virtualenv libopenjp2-7 git
|
|
$ git clone https://github.com/Protospace/protovac.git
|
|
$ cd protovac/
|
|
$ virtualenv -p python3 env
|
|
$ source env/bin/activate
|
|
(env) $ pip install -r requirements.txt
|
|
(env) $ python main.py
|
|
```
|
|
|
|
## Rasberry Pi Setup
|
|
|
|
### SD Card
|
|
|
|
Format SD card, mount on your own system.
|
|
|
|
```
|
|
$ cd boot/ # on SD card
|
|
$ touch ssh
|
|
$ touch wpa_supplicant.conf
|
|
```
|
|
|
|
Edit `wpa_supplicant.conf`:
|
|
|
|
```
|
|
country=CA
|
|
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
|
|
network={
|
|
ssid="YOUR_NETWORK_NAME"
|
|
psk="YOUR_PASSWORD"
|
|
key_mgmt=WPA-PSK
|
|
}
|
|
```
|
|
|
|
Append to `config.txt`:
|
|
|
|
```
|
|
enable_uart=1
|
|
```
|
|
|
|
Optionally set up a cronjob:
|
|
|
|
```
|
|
$ cd rootfs/ # on SD card
|
|
$ sudo touch var/spool/cron/crontabs/pi
|
|
$ sudo chmod u=rw,og= var/spool/cron/crontabs/pi
|
|
$ sudo chown pi:crontab var/spool/cron/crontabs/pi
|
|
```
|
|
|
|
Edit `var/spool/cron/crontabs/pi` (optional):
|
|
|
|
```
|
|
*/5 * * * * # example command that runs every 5 minutes
|
|
```
|
|
|
|
### On Raspberry Pi

|
SSH into the Raspberry Pi for setup:
|
|

|
|
$ sudo hostnamectl set-hostname protovac
|
|
```
|
|
|
|
Replace "raspberrypi" with "protovac" in `/etc/hosts`.
|
|
|
|
Create "protovac" user:
|
|
|
|
```
|
|
$ sudo adduser protovac
|
|
$ sudo usermod -aG dialout protovac
|
|
$ sudo usermod -aG lp protovac
|
|
$ sudo usermod -aG gpio protovac
|
|
```
|
|
|
|
Edit `/lib/systemd/system/serial-getty@.service`:
|
|
|
|
```
|
|
ExecStart=-/sbin/agetty --autologin protovac 9600 %I mt70
|
|
```
|
|
|
|
Edit `/etc/passwd`:
|
|
|
|
```
|
|
protovac:x:1001:1001:,,,:/home/protovac:/home/pi/protovac/main.py
