Hey Matt, I am struggling to understand which device and which programmer to use etc. Does the PICKIT3 replace the PICKIT2? What is the MicroChip low cost solution for programming the PIC24 line? And here is another one: I read on the product page of the PIC18F2620 that it has some sort of extended something that allows it to have a flat address space and some optimizations for C compilers, etc. Somewhere (likely on this list) I recall reading that this is true of all 18F parts, but I may have that wrong. It certainly seems to be the case for the 18F2620 however. If true, then the 18F product line is a sure winner over the older 16F product line with the program memory banks and the bank registers. Lastly, is there a PDF document that explains/summarizes the machine language of the 18F (or the 24F) product line assuming the device PDF documents don't describe the programming model (not the Flash programming model - that _is_ in there)? I seem to recall that the older 16F parts had such a programming document separate from the device PDF documents where all they have was an alphabetical list of the assembly op-codes and which flags were affected. I assumed there would be a similar PDF document for the 18F (and 24F?) product line, but so far I have been unable to locate such on the MicroChip website using their search engine. Thanks in advance.
