Is SX-48 code the same as SX-28 code?

Other than the chip designator, could I just program the SX48 with the same code as the SX-28?

I am just wondering because I have to do a do a project revision which requires more pins.· Instead of re-writing the SXB code, I would like to just copy it over, and add the new elements that I need.

Thanks
Shaun

    In theory that is the way that it is supposed to work. I used·JonnyMac's UARTsirc program that was written for the SX28, which worked as advertised, and I tried to run it straight up on an SX52 proto board, it did not work out. All I can say is that their are some subtle differences that you may be able to fix. I believe that SX/B is geared for the SX28, and that is how the support works out. I think Bean has worked with the SX48 more than I have, and he may have some advise as to what to watch out for.

    You should have very little problem getting SX/B code written for the SX28 to work on the SX48. The compiler handles the conversion. Just change the DEVICE line.

    Oh one "gotcha" is that the SX48 has 2 LESS bytes for normal (BYTE, WORD, BIT) variables. This is because the RD and RE port use the global memory area.
