At the moment, when I power up the SX28 and observe the data received on Hyperterminal (Windows), I get 5f 27 00, which is not what I expected from sending "A" then $62 from the code. The SX28 to PC connection is simply: RA.1 to DB9 pin 2 (RX), SX28 vss to DB9 pin 5 (GND) Protocol is 57600, 8 databits, No parity, 1 stop, No flow. I haven't progressed onto making the serin part work correctly yet, and first I wanted to be able to transmit/serout to the PC correctly. Hopefully by understanding the solution to the first part, I will have learnt enough to solve the 2nd part (if indeed it needs solving from what I have already!) But on the first part I have tried lots of different settings, and still seem to fail. So I would really appreciate your suggestions! No doubt it is something simple - I only started with this SX dev yesterday!
