writecode - problem - 18F6720

[Tomasm]

Hi,

I use PBP Pro 2.45, MPLAB 6.4, and Pic 18F6720. I want to write and read from code memory. But my small sample program doesnt work:

x var word

ERASECODE $5000
Pause 20

x=123
WRITECODE $5000, x
Pause 20

READCODE $5000, x

hserout [hex x]

hserout puts out "65535" but it should put out "123". When I read with readcode a word from the program- codespace the right content will
be displayed.

I disabled all protect- configurationbits.

Any ideas where my mistake is?

Hello Dwayne,

i know Melanies answer in this thread, but I cant use the PBP mnemonics, because I work with a 18F6720, so I have to use MPASM.

And the writecode example from Melanie doesnt work with my 18F6720!

Dear Tomasm, you can use PBP to do your code. MPASM will only translate your .bas file into an .hex file to be place into your PIC.


better for you to update MPLAB to new version 6.6x

after that you have to do EXACTLY the following instruction to include PBP into MPLAB. This will work

don't forget to reboot !!!

many regards.
