Hi Amos,

Before you blame the compiler lets try to check on your code first.

you say that the variables you used are pointers, well so you should to use 'em as such.

for example:
PORTC=0xAA;
will modify the pointer itself, it will point simply to 0xAA - sure you wont get any /WR response by that.

try
*PORTC=0xAA;
instead, this will write 0xAA to the address where's PORTC is pointing to.

BTW, when posting C programs make sure you post them as a whole, or better say'd: the declarations of all used variables in the listing should be included.

Cheers, Roger
