Challenge: why is the data I'm sending, blue/yellow, different than the white reference waveform, when it's the same data going through two different software packages. Also this would be so much easier with a logic analyzer than doing it all on a scope.

Not my field, but I'm curious about this odd behaviour.

@GustavinoBevilacqua@mastodon.cisti.org the software stacks both take an address, a register number, and the data to put in that register, then calculate parity and modify the address, then generate a CRC of the whole packet and splice that into thr middle of the packet, so a single bit change makes a huge change to the packet, and also one stack may not be calculating crc's correctly
