Hi All,

I have to decide which uC to use in my intelligent battery charger.
At the moment I can see two possibilities:
PIC16F877 and Atmel AVR 90S8535. Prices of both are almost equal there in
Poland, both feature 8 channel/10 bit ADC, two channels of PWM and similar
overall performance. Well, AVR has only 4 kwords of programm memory, but
in fact on an AVR I can do with the single instruction something which requires
two ops on a PIC.
The main differences are in the developments tools. I'd like to use free and
preferably open source tools to complete the design (it should be a
didactical design). For PIC there is a wonderful GPSIM simulator, able to
simulate even the ADC converter... I couldn't find any equivalent open
source or even free tool for AVR.
But OTOH for AVR I have a very good GPL'ed AVR-GCC compiler, (and from the
didactic point of view it would be much better to program the thing in C not
in assembler). For PIC I couldn't find any good open source high level
language compiler/interpreter (the best one was "mary" a PIC forth compiler,
but unfortunately even the last development version obtained directly from
the author does not seem to be mature enough, the next candidate could be
JAL, but it is not open source).
I would appreciate any suggestions, pointers for the tools and other hints.
