PINx value is meant to be levels on wires and cannot be changed
currently in the same manner as "true" registers. There's TCL ui which
probably can do that externally but personally never tried that.

Hi everybody!
I want to try debuging GNU ASM programms by simulavr, but have no ideas
how to change registers values while step by step debuging, i.e.
simulate events
=======exampe.S=======
#include <avr/io.h>
#define SFR(X) _SFR_IO_ADDR(X)
temp = 16
START = PD0
STOP = PD1
.section .text
.global main
main:
rjmp init
init:
ser temp
out SFR(DDRB),temp
out SFR(PORTB),temp
clr temp
out SFR(DDRD),temp
ldi temp,0x03
out SFR(PORTD),temp
waits: sbis SFR(PIND),START
rjmp waits
nop
nop
nop
nop
rjmp init
============================
Compile:
avr-gcc -Wa,--gstabs -mmcu=atmega16a example.S -o example.o
Simulavr - start server and watch registers state:
simulavr -g -P simulavr-dip -X -d atmega16
How I can change PIND state? I'm using Emacs as IDE.
Best Regards
Valber
