# RPi Control Tec via Python and CAN

This Script helps you to Control the TEC via the CAN Bus directly.
It is outdated and not maintained anymore, because we have now [Tessie](https://github.com/ursl/tessie).

There are 2 options, via the USB to CAN adapter (from seeed studio) or via the can hat for the Raspberry PI

Because we don't need it anymore, i will not further document this, but i published it because may someone want to use it to control the TEC directly

in the tec.py file are also some TEST Routines for testing the TEC and controlling it, also with logs


## Install the CAN interface (for RPi CAN Hat)

Add the following line to your /boot/config.txt file:
`dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25,spimaxfrequency=2000000`

`sudo reboot`

`pip3 install python-can`
... for python module

maybe edit permissions
`./resetCAN.sh`
... for starting can0
