EEPROM write in PIC16F688
PostPosted: Tue Jun 16, 2009 6:14 am     Reply with quote

Hallo Everbody,
I have the problem, that I can not write the internal EEPROM of the PIC16F688.
I am using MPLAB with the CCS Compiler.
The compiler brings the following Warning and Error:
Quote:
>>> Warning 207 "Pyranometer.c" Line 236(1,1): Code has no effect
*** Error 76 "Pyranometer.c" Line 236(15,16): Expect ;

My code is:
Code:

#define SpBuffer   0x20
int dummy = 1;   
WRITE_EEPROM(SpBuffer,dummy);  //LINE 236

If I am using the PIC16F873A, it seems not to bother the compiler and there are no errors???
Is it a bug with the PIC16F688?

I will be thankful for your help.
Smile

The fault is almost certainly earlier in the program.
CCS has a 'habit', in it's error reporting, that if you make certain types of error, in lines, they are not 'spotted', till you reach another piece of program, where the error then results in a syntax problem. The actual error wll be several lines _before_ where the error is 'reported'.

Best Wishes

If you still can't make it work, then post a small test program instead
of code fragments. Example:

Also post your compiler version. It's a 4-digit number in this format x.xxx
and it's given at the top of the .LST file. The .LST file will be in your
project directory (after a successful compile, with no errors).

there is an even faster way to find your version w/o any input - or a good compile - no source file required .

in the comand line compiler - just type:
+V

in the file name window and hit enter.

/?

is also a handy command in that it tells you all the OTHER commmand line options - in your current version of the compiler

ESPECIALLY the list of ALL SUPPORTED PICS !! VERY helpful that one

you get a screen that tells you all that you need to know .
