Re: [avr-gcc-list] Some working example code for ATMega163

[Larry Barello]

I recently rebuilt my robot code (www.barello.net/Robots/Dilbert2) as 163
vs 8535 and aside from two hitches worked perfectely out of the box:

1. The mega163 I got had the internal R/C oscillator set - until I figured
this out and reset the fuse bits the code ran real slow...  By the way,
there are a *lot* of fuse bits for that chip.

2. I couldn't get the code to run reliably until I bumped the Vcc to 6.0
volts (STK500 - great development board) - then I finally figured out that
9.86mhz crystal was actually 16mhz - oops.  Once I got a proper 9.6mhz
crystal (yeah, I know, I am overclocking the chip) things worked properly
down to 3.0 volts or so.

As far as I can tell, aside from the 4 byte entries in the interrupt vector
table and the usual shuffling of vectors, everything else is backward
compatible with the 8535, bit for bit.

Cheers!
