Kindly request that you point me to the documentation as I can not seem to find these data sheet registers for the life of me.

For example, I would like to send the CAN messade ID 0x43F over 8 bits starting at Bit 0 with the decimal value of 13976218851319218176 when "Forward" direction is selected.

Can this be done over the web interface or CLI?

I have a Tesla SDU with an openinveter board v6. I am wondering if it is worth upgrading it to a v8 board or if I just upgrade to the 5.27 firmware.

LTC6803 introduced a CRC so you would need to add to the driver code in order to use it. however is pin compatible so no PCB changes. I bought a bunch of ltc6802-2 from an Alibaba IC sourcing company since their min order quantity was 50 units. They have all worked flawlessly so far and I have so m...

Thanks so much! Definately the right direction.

A list of the necessary tools will also be appreciated. Pointers to any existing posts/threads will be appreciated. I have a couple of SDU invert...
