Should have mentioned this also but here goes:
I have 2 of these modules and had them connected first to 2 arduino’s. They were happily married, uhm, exchanging data. Now the plan is to move 1 transceiver to the panda and receive the data that the other arduino is sending every 5 secs. I’m absolutely positive that at the hardware level everything is ok. What I suspect is that 1) I miss a command to read the buffer 2) that commands to read the buffer are not in the correct order.
I have analyzed the arduino driver for 5 days, but my c++ knowledge is pretty low.
And no, i don’t have a protocol analyzer or a DSO (would love to have one though), and i don’t think pincapture can help here since the transceiver is an SPI device.
