| #BYTE register declaration |
 Posted: Wed Dec 18, 2013 12:30 pm |

Hello all,
CCS Version : CCS PCD C Compiler, Version 5.006, 7054
Chip used : DSPIC33FJ09GS302
In my program, I declare two registers :
#BYTE CMPCON1 = 0x0540
#BYTE CMPCON2 = 0x0544
and, a little further, I affect values to them :
CMPCON1 = 0x8585;
CMPCON2 = 0x0485;
but, here is what the compiler has traducted (in .lst file) :
.................... CMPCON1 = 0x8585;
03D0: MOV.B #85,W0L
03D2: MOV.B W0L,540
.................... CMPCON2 = 0x0485;
03D4: MOV.B #85,W0L
03D6: MOV.B W0L,544
It writes 8 bit value, and I've asked for a 16 bit value. I imagine that I wrote something wrong.
Can you help me dealing this problem ?
Here is the whole code (it is in debugging state) :

| Almost. You want #word not #byte. |

real close !!
you have ...
#BYTE CMPCON1 = 0x0540
...which means that 'CMPCON1' is 8 bits long( a byte) located at 0x540
you really need
#WORD CMPCON1 = 0x0540
...which means that 'CMPCON1' is 16 bits long( a word) located at 0x540

A big thanks for the help.
It works perfectly now (at least for this part ^^).
Have a nice day. |

As a comment, there is also a way of doing larger things.
#BYTE can be used two different ways.
By default it creates a 'byte' sized variable at a location. #WORD creates a 16bit variable at a location.
However you can also use it like this:
| Code: |
int32 val;
#BYTE val=0x1234
|
Done like this, #BYTE _locates_ the already defined variable at the specified memory address. This allows you to define things like fp values, or even arrays at a particular location in RAM.
Can be useful sometimes. 
Best Wishes |
