Hi and thanks everyone.

Using a combination of Lookup and assembler

the code is now 3768 !!!! beauty !

I noticed that lookup can reduce code but can also
increase code, so be carefull !
...

a minor :) oversight !
The demo PIC had 8k,
final PIC ONLY 4k !
Suggestions to shrink code, please !
I have already used ASM/ENDASM where possible,
have used minimal GoSubs,

Hi Mister e
I have finally got most of it sorted.
I used the line

and hey presto

Hi Guys, Hi Melanie.

I had a problem with how to program or assemble the 18F4320, The forums kept saying, and very correctly, use MPASM.

Hi,
I am trying to control the volume of a piezo by PWM, but

Why wont this compile ?!

Hi Daryl,
Must have been your telepathy, as I did precicly that, ie

div32 first THEN subtract

ADCIN 7,y

Pause 100 ' adc settling

x1 = y

Page 31 4th line down in mine says

** Top 16 Bits of Multiplication

I also found the DIV32, however ?

May I inquire what you were saying, please

Pete

OK, Brain Freeze !! (At the moment I cannot even get a slope formula right !)

This is what I am trying to do

ADCIN 6,x

x = x*2923-1343923

Hi,

I would like to use a pin as both analogue and digital inputs.

1st it needs to be digital to allow ICSP, and then

Any suggestions...

Hi,

Do you have to use the assigned ports on a PIC to I2C ie SCLK and SDAT or can you define them ?
