I’m getting some fairly erratic results with the SD cards. Some of the time it saves as it should, or at least this seems to be correct on the device. Somethines I get SDerror.
The other thing I have noticed is that when using dat2bmp to retrieve screen prints that the Saved position on the Nano ie File001 sometimes does not match at all the file name ie I am finding it on File000.dat. There is more weirdness going on…
