Output stays high

[ozzieB]

Hi,

I am working on a program with 3 switches and 3 LED's.
Every switch is connected to 1 LED.

what i want, is that when i push Switch1, LED1 must go on but when i release the button LED1 must stay high until i pressed Switch2 again.

can someone help me?

Hi, Ozzie

This is a pure logic question ... but your problem is not clearly enough explained : no " cooked " solution available with so little detail given ...


so, you could have a look here :

http://karnaugh.shuriksoft.com/

this would help you to write

Led1 = Button1 + ? ....
Led2 = Button2 + ? ...
Led3 = Button 3 ...


Now you also can try to do it the " hard way " using some SELECT CASE statement ... lazy boy solution !!!

looks some school homework , no ???

May I state it's YOUR exercise to define what has to be done for wich input combination ...

AND we're supposed to help for programming the PIC application ...

In short words :

The logics problem is yours ... not ours to solve.
