Did you try the simulavr-disp program? It can be started by

simulavr as such:



simulavr -g -P simulavr-disp -d at90s8515



That will display the IO registers for you (at least the

ones that simulavr supports).



To write to a register from gdb, you need to do something

like this (if remember correctly):



(gdb) set var *(unsigned char *)0x800038 = 0xAA



which would write 0xAA to PORTB.

Hi!



Yesterday I played around a while with simulavr, gdb

and ddd.

Simulation of test programs worked fine, but I haven't

found a possibility to read and set I/O ports.



After reading the docs (and exercising USTL), I think I

have to use a display process to show IO-Ports. But

I've seen no way to set them.



1. Is this right?

2. Are there any good display programs out there?







Thanks, Euphi
