PIC 16F84A & PIC 16C56A

[wutc]

16c56a

I write a program that can be running in 16F84A but can't run in 16C56A.
In the include file,i have change to "pic165x.h" from "pic16f84".
Who can help me thk.
I am looking for IAR for pic not for pic18,too.thk

best regard!!

internal structure of a pic16f84a

hi there,

what kind of program have you written? as far as i can remember, internal structure (registers size etc.) is different in both µs, and more importantly, PICs are (generely) not downward compatible.

I have IAR EWPIC, but it is not the actuall version. It is about 9MB.
how can you collect it ?

16f84a stack

This program is written with C language.

It is hard to tell you what to do without haveing a look at both the schematic and source code. Make sure u include proper header files like eg. PIC16C56 in your c code. Check your code and possibly rewrite sections that are precessor dependant eg. timers ( 8 bit vs. 16), interrupts etc. If you written the source in c, that should not be a problem.
Cheers

Hi,

i work many years ago with pic , if i remember corect the 84 have a differet stack depth , i think th 56 have only a 2 level stack.
if you call moretimes subroutine from subroutine you will loose the return-adress, check the struckture aof the programm....

i hope its help you

bye

PICS are different

All PICS have different architectures for example :

- All have diffent number of ports
- All have differnt register mappings
