help with code

agfa

could someone take a look at the code i have attached, and let me know whats wrong.· i'm sure it's something simple but i've been fighting it for two days now and i can't seem to see the problem.

its supposed to detect a zero to one transition on pin 6.

it appears to me that the statements after the if condition are met, only occurr once.

Hi agfa,


Change your if statement to this and it should work....

if !prevl & newl {left encoder 0 to 1 trans}   

compares if pevl is 0 and newl is 1

Regards,

Coley

EDIT:

I forgot to add, that you also need to make

prevl := newl

part of the main repeat loop, presently it is only executed as part of the IF statement
therefore the code would only work once.

thanks Coley,

changing the location of the "prev1 := newl" got it working. i never would have thought of the if statement you suggested. nice. if anyone needs the most complicated way to do a simple task, just ask me.
