error with asm code
PostPosted: Fri Oct 23, 2009 9:11 am     Reply with quote
i've tried to set the adcon2 register of a dsPIC30F3013 with 0x2000.
to do this i've wrote this asm code:
Code:
#asm
MOV     #2000,W4
MOV     W0, 2A2 ; 2a2 is the adcon2 register adress
#endasm

when i try to compile the program says:
"error 102 expecting comma"

thanks to anyone who can help me.

P.S.
I'm writing this code because the ccs function  setup_adc_ports(sAN0|sAN1|VSS_VREF) does't work. The ADC does't use the Vref+ but it use the aVdd like Vref.

I don't know anything about that processor, BUT have you tried the
classic way of accessing registers?

#BYTE

Code:
#byte ANSEL =0x188
#byte ANSELH=0x189



Then in main

  ANSEL=0; //the above statements don't work correctly.  Using #byte to force it.
  ANSELH=0;

As an alternative to two #BYTE declarations you can use a single #WORD to access the register as a 16-bit.

Code:
#word ANSEL = 0x188


Then in main:
  ANSEL=0x2000; //the above statements don't work correctly.  Directly access the ADC register to force it.

The #word declaration works.
Thank you.
I've tried the #byte declaration but for some reason it doesn't work.
