SX/28 PIC compatibility

Wreno

As I understand the SX/28 is kind of a PIC on steroids, the question is: Can you use a PIC programmer like the EasyPic3 to program the SX/28 And to debug the operation? If so, any particular gotchas I need to be aware of?

Reason for the question - have a friend in our club that is a PIC chiphead, with lots of PIC tools, and am wondering if we can expand into the SX (where I believe I want to end up) easily?

Thanks,

Wreno

No.
The Pic programs through a completely different kind of portal.
Take a look at the Fluffy Two programmer if you want to compare the two.
The SX chip programs through the oscillator pins at a higher voltage.
I forget what the PIC does, but it isn't the same.

And if you look at the Pin Outs for the SX-28, they are not the same as the 28 pin PICs.

BTW, it isn't really worth building a Fluffy as the SX-Blitz is priced competatively and is comparatively as cheap or cheaper.

Debug will require an SX-Key. You might as well get the whole package with Guenther's text unless you really find it easy to switch from PIC Mnemonics to SASM Mnemonics. The additional instructions are particular to the larger program memory and RAM.

If you really want to avoid buying the books, you still might work through all of Guenther's tutorial examples to comprehend what is going on.

Nevertheless, you can find several tools that will help you migrate PIC code to the SX on the www.sxlist.com site.
