# 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It is outdated and not maintained anymore, because we have now [Tessie](https://github.com/ursl/tessie).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)
