These little $2 gadgets arrived today.

It's basically a CAN line driver and a MCP 2515 CAN module chip on a nice little board with SPI interface to a PIC.

So two of these together and one cheaper PIC might be better than two $$ CAN enabled Pics

Anyway more toys to play with..

I use the MCP2515 modules with Arduino Nano boards. Seven wires and you're reading CAN bus. With a Raspberry Pi and seven wires you can read and send CAN bus data, without writing a single line of code. Just attach it to a CAN bus, and run the candump program and pipe it to a file and you can sniff until the SD card fills up.

I have an active balancer that would gladly keep the LiFePo4 pack balanced and report all the cell voltages, which I can easily connect to an ESP32 and write my own code to respond appropriately, but I lack the ability to tell the MCM what to do.

Unfortunately as I don't have an HCH2 now my focus has moved to the CRZ.
This thread and HCH2 research is unlikely to be updated.

Since you are abandoning the HCH2 work, would you consider contributing the source to the community? This would let folks like @Techie007 run with it. The best way to do this would be to create a repository on github.com and place it there.
