The Tesla Battery Current Shunt, not alot of attention has been given to this component out of the pack. Which is a shame as a good current shunt is a useful tool.
Using a multimeter and scope I worked out what signals were shared between a master board and the shunt. Turns out they use SPI, quite strange considering the slaves work on serial (however using a bastardized spi protocol).
All info on the github link:
https://github.com/tomdebree/Tesla-Current-Shunt
Current software:
-initialises the shunt
-reads out the 'current' value conversion factor yet to be determined.
Guess I will now make a simple converter board.
Note: USE AT OWN RISK ground of shunt is HV GROUND
