After last week's excellent progress, this week has been rather the opposite. Partly that's because I've been busy with the annual inspection on my aircraft (rather like an MOT on steroids) and I've spent a lot of time at the airport fixing ground-based radio systems.
The new display shield arrived and I have done some initial testing. Rather disappointingly, it has heralded the return of my SPI issues, for reasons that I cannot for now fathom. The problem is slightly different - now the Ethernet or the SD card break the display subsystem. I need to find some quality time to investigate further.
And that is about it. I hope to have a little more progress to report next week.
