# BlockyGrapher
Query grapher for Blocky DNS Server
## Install python packages
Debian-based:
```bash
# install system packages
apt install i2c-tools python3-dev python3-pip python3-numpy libfreetype6-dev libjpeg-dev build-essential
# Give user permission to use i2c interface (Replace user with your name). Remember that you need re-login to user after this (You can reboot too if it didn't work for some reason).
usermod -a -G i2c user
# install python packages
pip install -r requirements.txt --break-system-packages
```
## Finding right port
`i2cdetect -l` can help to find port you need to use.
Schematics for your adapter/board can also help.
