BS2sx Program Help

I wrote a program but want to start it with a push button.· I have it wired to input 6 on the stamp and know i·need·an if...then...else statement.··I want to know if anyone knows how to write a program for this.·

Try a DO...LOOP with an EXIT command, like this one (from the manual):

DO
  READ eeAddr, char ' get character from DATA statement
  eeAddr = eeAddr + 1 ' update address pointer
  IF (char = 0) THEN EXIT ' if 0, end of string
  DEBUG char ' otherwise, transmit the character
LOOP ' get next character
RETURN

Loop back until the button is pressed, as tested in that IF...THEN statement.

As an alternative:
MyButton PIN {whatever pin you have the button on - I'm assuming it will be active High}

DO Until MyButton=1
'Add other stuff that may run waiting for the button - but not too much that it can miss the press
Loop

collegenow09,

There are a few ways to complete this task. Put a pull-down resistor on the button and this will ensure you do not get a false trigger. You can split the code up into two pieces, the first one to watch the button and the second to be the program you jump to. Here is a quick example for your review, this should get your started on the right path.

:: Example ::

DO
·· IF IN6 = 1 THEN GOSUB MainProgram
LOOP

MainProgram:
·This is where your program will go
RETURN


I hope this helps
