I have a doubt all of a sudden. What I want to do here is to load FSR0L with the lowwer part of ee_block[0] address and FSR0H with the upper part of it.

MOVFF &ex_block[0]+1, FSR0H is going to ...

Thank you for your cooperation

Here is the routine (it hasn't been cleaned up). When I use &ee_block I get an error at compiling saying"expecting an identifier"

#BYTE TBLPTRU = 0xff8
#BYTE TBLPTRH = 0xff7
#BYTE TBLPTRL = ...

That's right. I just wrote those lines as an example but in the original file the declaration of the variables are right.

I tried MOVLW &ee_block +1 already but the compiler says expecting an identifier and gives an error

I still have big troubles while writing in FLASH memory with a 18F442 and had to implement assembly language routine specifyied by microchip datasheet but this is not the debate right now.

My quest ...

The magic is a small detail ! If you use the routine as it is in the datasheet on a 18F442 it doesn't work. You just have to change the way the GIE bit is handled. I clear the bit GIE just before the ...

Thank you very much. In the meantime I figured out a solution by modifying the write routine in the 18FXX2 datasheet. And now everything works ! I'll clean up my code when I get out of the rush situat ...

Hi,

I've just read a message of a bug, present last year on CCS 3.177, that has similar symptoms as the one I'm experiencing whatever version up to the last one 3.206.

In fact, when using the w ...

I missed something int he calculation of the relative jump. As specified by the datasheet the relative jump is calculated by the following formula 2n+2. And the BRA instruction previoulsy mentionned i ...

Bug has been reported to CCS. For those of you who are experiencing the same problem, I solved this specific problem by adding #opt 5 while keeping 3.202 version.

Thanks to C-H Wu for this good adv ...

I think I finally found a problem. Hereafter is a Branch instruction at the end of a for(;;) loop

The code optimization replaces a ...

I've just tested version 3.202 with the #opt 5 you mentionned. And now icons are displayed perfectly well. I had a look at the lst file and find GOTO instructions instead of BRA at the end of for(;;) ...

Thank you for your help

Yes, I tested it. It doesn't work. I have a subroutine tha displays graphic icons on LCD. No icon displayed. This is probably the visible part of the iceberg, I didn't track ...
