goto $+1

[Douglas Richard]

I want to get the most compact delays that I can.

However the below code will not compile.

#ASM

goto $+1

#ENDASM

Any thoughts?

You could do this as a work-around:

#asm
goto label
label:
#endasm

With or without the #asm the above code will compile. However no code is generated for the two cycle delay (per list file).

Here is a test program that I compiled with PCM vs. 3.169.
It works OK.

<PRE>
#include "c:\Program Files\Picc\Devices\16F877.H"
#fuses HS, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
//#use delay(clock = 8000000)
//#use rs232(baud = 9600, xmit=PIN_C6, rcv = PIN_C7, ERRORS)
<BR>
//=========================
void main()
{
<BR>
#asm
goto label
label:
#endasm
<BR>
<BR>
while(1);
}
<BR>
<BR>
Here is the .LST file:

0000 00266 .................... void main()

Where I am putting it to use it is not working:

do
.................... {
....................
.................... delay_us(351); // need 366us delay between transmitions
0212: MOVLW 74
0213: MOVWF 20
0214: DECFSZ 20,F
0215: GOTO 214
0216: NOP
0217: NOP
....................
.................... #ASM
....................
.................... goto lable
....................
.................... lable:
....................
.................... #endasm
....................
....................
....................
.................... i--; // (15 to 0)
0218: DECF 47,F
....................
.................... if ( bit_test(output, 23) )
.................... {
0219: BTFSS 3D.7
021A: GOTO 223

Try it with the "ASIS" keyword. That should make it work.

#ASM ASIS
goto lable
lable:
#endasm

ASIS did the trick.

Thanks for putting in the time and effort to help me.

When all is said and done you helped me save 2 program words. It may not sound like much but every little bit counts when you are using the 12F629 and only have 2\% of the memmory remaining.

Thanks again.
