I am new to the sx as well. I have been prototyping different circuits on the sx tech board with the sx28 and am now combining them on an sx48 protoboard. I found the transition not too difficult.

There is some weirdness with bank 0 ram on the sx48 that I don't quite understand yet, I just avoid using it. Also at first I was using the sx_key assembler but discovered that sasm is now recomended, this confused me since I am using the sx key product, do I have this right? Also I didn't see any documentation on the carryx directive which seems to cause add and sub to use the carry/borrow flag but is not the default, at least not in most of the sample programs I looked at, except in the math routines, took me a while to figure out why they weren't working.

Love the sx chips though, gives you way more control than with stamps, although coding is slower going at least until I get more proficient. I am building a device to profile racing canoes. I have accelerometer data being collected by one vp (paddler stroke rate & power) and two serial vps, one to collect positional data from a gps and one to send data to a data logging device (palm pilot) for storage, display and summary.
