Hi Tamas,

The TechTool manual includes the translation for each of the TechTool
instructions.

When I was working with the MicroChip processors, the only C complier was
expensive.  The other problem I had was that my TechTool ICE would not
handle the newer 18F chips.  I have done development so long now with an ICE
(since the early 80's) that I did not what to take on a new chip without an
ICE.  Being a high school science teacher, I was able to get 10 free QSK26A
from Renesas University for my classes to use.  Very similar marketing that
Apple did with the elementary schools many years ago.  =


Anyway, I found the Renesas easy to use and move to it.  I started out using
the RCA 18Cxx series of microprocessors before moving to the Microchip
controllers.  Times change and so do our taste in uprocessors. =

Kind regards,  =


David

The only problem with that is that you never know the exact
translation to the Microchip instr. set, do you? For example that DJNZ
at least 2 instructions (DECFSZ + GOTO), and not sure if they handle
banks and pages? Or if they do how?

In my opinion it would be better off with a C compiler if you need to
jump in between different MCUs.
