I compile a simple program for the PIC14F84 using gpasm...
lab:~/HelloWorld#gpasm HelloWorld.asm
HelloWorld.asm:51:Warning [224] Use of this instruction is not
recommended.
HelloWorld.asm:52:Warning [224] Use of this instruction is not
recommended.
I attempt to write it to the pic...
lab:~/HelloWorld# odyssey PIC16F84 write HelloWorld.hex
Address: 0x000000, 0% done
odyssey: PIC16F84: Couldn't write program memory at address 0x0000
Okay so I spend several hours debugging my hardware (simple
programmer I built on a breadboard...
yelling, mashing of teeth, etc :-) Can't find anything wrong.
Then I try reading the PIC...
lab:~/HelloWorld# odyssey PIC16F84 read tim.hex
Address: 0x002007, 100% done
okay so it must just be a writing issue. But just for the heck of it
I try writing what I just read...
lab:~/HelloWorld# odyssey PIC16F84 write tim.hex
Address: 0x002007, 100% done
So I have concluded the the hex output from gpasm is not compatible
with odyssey. Can anyone confirm this? I'm I just doing something
stupid?
Thank you
