Sequencer

Hi All:
Here is the example of program written in PICBasic Compiler and adjusted
to use in PICBasic PRO compiler to generate sequence on 6 pins PORTB in different ordrer and use PULSOUT function as timer on pin 7 because in
PICBASI PRO Compiler I couldnot find any function to do that.
Regards,
Leonid

Waaay to much programming for me, dude.

' kitt 1
for loop=1 to 20' do kitt twenty times
for j=0 to 7: portb.0(j)=1: pause 40: portb.0(j)=0:next j ' pause 40 is on time
for j=7 to 0 step-1: portb.0(j)=1: pause 40: portb.0(j)=0:next j
next loop
goto _____
end

or,

for loop=1 to 20' do stay lit twenty times
for j=0 to 7: portb.0(j)=1: pause 40:next j ' light 'em up
for j=6 to 0 step-1: portb.0(j)=0: pause 40:next j ' turn 'em off
next loop
goto _____
end

simple huh? This applies for nearly all pics using portb, or c, or d, or a or whetever.

so, what is this for? just makes some LED's turn on? lol
