Specifically post #32 where there's a download link to the beta version of PBP supporting Q43 devices but also post #49 where updated/corrected library files are available (to replace those that comes in the 3.1.4.4 download).

Get input data into buffers, parse with ARRAYREAD, populate output buffer and send. Might be a good candidate for some DMA-action :-) I wonder how hard it would be to make DT-Ints work on this device, I have a Q43 devboard on the bench, using it to write code for MCP25625 at the moment but have not tried anything DT-ints yet. Oh, the vectored interrupts is tempting too. I'm rambling so I'll just shut up now :-)
