Cerbuino Bee - Just one SPI channel?

@Aron

@ devhammer - do you have a data bus analyzer? You could hook up your analyzer to the N18 screen and see if the data is the same between the two boards. If the pin is working, but the N18 is still not functioning, then the processor’s SPI controller is probably damaged.

Unfortunately, no, I don’t have a data bus analyzer. A Bus Pirate is on my wish list, but haven’t gotten around to getting that yet.

Given that the boards I tested the N18 on are the same revision, running the same firmware, I’m thinking it’s a safe bet that the SPI controller is toast on the board that isn’t working for SPI.

A bummer, but I’ve got at least two other Cerbuino Bee boards, so if this one is relegated to non-SPI tasks, it’s not the end of the world.

And just as an FYI, PWM appears to work fine on socket 1 as well. So looks like it’s just the SPI that’s bad.

Thanks for your help troubleshooting.

@ devhammer - No Problem. That is what we are here for. When you do get that Bus Pirate, it would be interesting to see conclusively if just the SPI controller was damaged.
