PIC18f4220

[jcullins]

I am trying to program the pic18f4220a chip and get the error message
code programming error at 0000.
Is there an example using this or any other pic18f chip ?
Thank you
Jim

I forgot to add I am using
Pic Basic Pro ver 2.46
MeProg ver 3.3
micro studio plus 2.3

Is there a MCSP 2.3 version?

On their site is only 2.2.1.1

Yes, you should be able to down load it.
Have you programmed the PIC18f4220 ?
I have an example file form MELabs that compiles
but when I try to program it it comes up with "code error at 0008"
I am wondering if it is my 40 pin ZIF socket on my programmer.
Is there one just for the 18f series . Mine is the one I have used
with the pic16f877 chips.
Thanks
Jim

Is there anyone out there using this chip ?
I don't seem to get a response from anyone.
I think my problem is with the assembler MPASM but not having used it
before I don't know.
I compile with PBP it is OK
assemble with MPASM OK
try to program with the MELabs serial programmer and it give this error

code programing error at 0000

or somethin like that.
Is this a set up problem?

Hi,

Normally all Program memory location are default $FFFF (nop). So you can check your PIC if it reads okay. If it reads $0000 then its your programmer. What a programmer does is dump the hex files in the prog. memory locations and just verifies it while/after programming. In most cases if your first location is not being programmed then your programmer has some communication error with the PIC. Even parasitic capacitance on the data and clock lines make it worse.
