Kinda lost...

BaTWING_2000

On page 227 of the what is a microcontroller it is asking me to:

"Modify MixingTones.bs2 so that it cycles through the Freq2 arguments
ranging from 2001 to 2005 using a word variable and a loop.

I'm dont exactly get what I'm supposed to do here. Anyone please help thx..

This is MixingTones.bs2:
========================================

' {$STAMP BS2}
' {$PBASIC 2.5}
DEBUG "Frequency = 2000", CR
FREQOUT 9, 4000, 2000
DEBUG "Frequency = 3000", CR
FREQOUT 9, 4000, 3000
DEBUG "Frequency = 2000 + 3000", CR
FREQOUT 9, 4000, 2000, 3000
DEBUG "Frequency = 2000 + 2001", CR
FREQOUT 9, 4000, 2000, 2001
DEBUG "Frequency = 2000 + 2002", CR
FREQOUT 9, 4000, 2000, 2002
DEBUG "Frequency = 2000 + 2003", CR
FREQOUT 9, 4000, 2000, 2003
DEBUG "Frequency = 2000 + 2005", CR
FREQOUT 9, 4000, 2000, 2005

DEBUG "Frequency = 2000 + 2010", CR
FREQOUT 9, 4000, 2000, 2010
DEBUG "Done", CR
END

It wants you to use a loop (either FOR or WHILE) to condense the code from about a dozen lines to about four. Look up how to use a loop to increment a variable.

yay. I think I got it [noparse]:)[/noparse]

=================
freq2 VAR word

FOR freq2 = 2000 TO 2005 STEP 1
DEBUG "Frequency = 2000 + ", DEC4 freq2, CR
FREQOUT 9, 4000, 2000, freq2
NEXT
=================

stupid me was focusing on the DO LOOP arguments and didn't think of the FOR NEXT
(even tough it was just covered). Yah I'm a dee dee dee sometimes. Thanks SRLM
