Please install python 3.6 on you PC / Raspberry PI

(If you are on windows, please change you CAN Interface in the uploadtec.py script) here some infos

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

Usage

to use this script the libopenblt.(so on linux)(dll on windows) library should be in the same directory.

on linux first reset the canbus with ./resetCAN.sh.

now copy the .srec file to this directory

the use the script to upload the code: python uploadtec.py [all/1-8] [filename.srec]

if the upload gets interrupted, the should restart the upload because th code on the TEC is now corrupted. The Bootloader itself should not corrupt itself, so everything is save. These are 2 completly different and independent programms.
