Streamlining Code

Posts: 46,084
I'm writing code to control a servo (used on a robot to open and
close the robot's mouth). I'm synching the servo movement to
prerecorded sentences recorded on an isd voice chip.
Everything's working great so far, except for one thing... I'm
running out of memory on the Basic Stamp 2! I've got about 1000 or
so lines of code, I'm assuming I have to get it down to about 500 in
order to make it fit on the Stamp2.
Short of investing in another Stamp, (the 2e for example), can anyone
help me figure out a way to condense the code so that it doesn't hog
so much memory?
Here's a sample of my code, this is for a single syllable in a
sentence:
'OPEN MOUTH
for x = 1 to 8 '(the higher the 2nd number, the SLOWER the servo
movement
pulsout 13, 400 + (x * 60) 'this moves the servo smoothly instead of
jerking it from point to point
next
'CLOSE MOUTH
for x = 1 to 8
pulsout 13,850 - (x * 60)
pause 10
next
I'm new to this. Can anyone think of another way to code this so
that it'll eat up half as much memory?
Thanks in advance.

and everything that is done repeatedly into a
subroutine. This can be done even if some values
change. For example:
' in section handling a sentence
cntr = 8 ' elsewhere value may be different,
' so set just before subroutine call
GOSUB CloseMouth ' will do subroutine then
' return to next line of code
.
.
.
' subroutines section
CloseMouth:
for x = 1 to cntr
pulsout 13,850 - (x * 60)
pause 10
next
RETURN

use parameters to tell only ONE routine to either open or close
mouth:
if want to open mouth, set startnum = 400, factor = 60,my_pause
= 0. then call subroutine
if you want to close mouth, set startnum = 850,factor = -60,
my_pause = 10. then call same subroutine
'either MOUTH
for x = 1 to 8 '(the higher the 2nd number, the SLOWER the
servo
movement
pulsout 13, startnum + (x * factor) 'this moves the servo
pause my_pause

with enough thrust, pigs fly just fine.
