How can I get input from a switch, ON/OFF, and use that to either enter a loop or exit a loop?
How can I get input from a switch, ON/OFF, and use that to either enter a loop or exit a loop?
Give this a try
Code:switch var PortB.0 main: if switch = 1 then loop ' enter the loop ' do some thing here . . . goto main loop: if switch = 0 then main ' exit the loop . . . loop code does something . . . goto loop
If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.
.
Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves

There simply is no "Happy Spam" If you do it you will disappear from this forum.
Code:WHILE Switch=1 'put some code here WEND

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
If I want switch to be linked to a pin, then how do I declare it before a loop to be an input?
Is this code done for the PICBASIC assembly or a version of BASIC as the name implies?
I did not see the first line, sorry, please disregard
Can someone read below, I was told to do this and I am still getting the errors below the code, What am I doing wrong still?
Thank you in advance.
code below:
---------------
switch var PortB.0
main:
if switch =1 then loop 'enter loop
'forward
high PORTB.7 'enable pin
high PORTB.6
low PORTB.5
high PORTB.4
low PORTB.3
high PORTB.2 'enable pin
goto main
loop:
if switch=0 then main 'exit the loop
'backup
high PORTB.7 'enable pin
low PORTB.6 'stop this side
low PORTB.5
low PORTB.4 'reverse this side
high PORTB.3
high PORTB.2 'enable pin
goto loop
