BMW E8x K-CAN BUS to GUI development using PiCan3 and Raspberry Pi. 00:44

Development of a GUI for BMW E8x Models CAN BUS interpretation. Taking CAN BUS data in via a PiCAN3 module on my raspberry pi. Then displaying that data on a web gui front end. Eventually I would like to make a CIC retrofit to my car. Still more work to be done but this is a preview. I run the PiCAN3 in loopback mode and then send CAN data into the bus which then is picked up by my python script and interpreted.
