#ORG solution not working with a "real world" large program (a 58ko hex file, for my current project). #ORG itself works, and puts isr code at the right place (checked on pic ROM). But [] op ...

Thank you for answer.

For a general use, i will dissociate interruption function from main function.
Both solutions :

1) I must use only elementary operations on interruption (add, shift, ...). ...

Hello,

I use
#include <16F1705.h>
#fuses INTRC_IO,NOWDT,NOMCLR,NOPROTECT,NODEBUG,NOLVP
#use delay(clock=32MHZ)

struct SDummy
{
byte a;
unsigned int16 value;
} ...

The answer is : NOWPDIS fuse

Datasheet :
"WPDIS:Write-Protect Disable bit
1= WPFP<5:0>, WPEND and WPCFG bits are ignored; all Flash memory may be erased or written
0= WPFP<5:0>, ...

Thank you.

Good news ! It work for me too !!!
I take exactly same C code. Compile it, and flash it on hardware pic. Then read memory with PicKit3.
Compiled code is strictly the same as you.
My m ...

Thank you very much for your test.

Did you have ASM or binary compiled code ? Thank you.

I am still not able to write PIC18F program memory with CCS ...
After many, many, many tries. Neither with ASM or C.
MPLAB simulator is not reliable. Memory self programming works in every way with ...

Thank you for informations.
You are true, USB is useless for my test. It's a bad copy from other project to get the FUSE and clock line. No impact on result.

I know that it is not the place to fin ...

I use ccsc 5.043 and Mplab-X 3.55.

New test code :
#include <18F27J53.h>
#fuses NOWDT,NOSTVREN,NOXINST,NODEBUG,NOCPUDIV,NOPROTECT,INTRC,NOCLOCKOUT,NOFCMEN,NOIESO,NODSBOR,NODSWDT,NOIOL1WAY,N ...

Thank you very much for your test.
Then the source code seems ok.

I usualy manage application config flash memory with an ownmade library (based on write_program_memory). It works with some other ...

C file is for "to compile" code. H (header) file for declarations (structure, class, function prototype, macro, ...).
With "normal" compiler, each .c files become an .o (object). ...

Hello,

I can't write flash program memory, by pic itself.

A simple example :

#include <18F27J53.h>
#fuses NOWDT,NOSTVREN,NOXINST,NODEBUG,NOCPUDIV,NOPROTECT,INTRC,NOCLOCKOUT,NOFCMEN,NOI ...

YES !!!!
Thank you very much.
I replaced a macro (define) by sAN3 for my test. It was wrong.

This small program works with :
set_adc_channel(3);

Now i can compare and search why my main progr ...

Hello,

I use 16f1705 on a large project, and i have strange behaviour from it's ADC. Returned value is always 1014(dec).
If i use ADC_CLOCK_DIV_2 instead of ADC_CLOCK_DIV_64, value is random (358, ...

I found a clue ...

It seems that both interruptions are mixed.
On RC changes, #INT_RA is called.
I try this code :

#INT_RA
