will it hurt prop 1

[tj]

jon i spoke to you earlier in the week, i ordered the starter kit yesterday. Is it possible to mess it up by writng a bad code, or will it just not do anything? I look in the programing basics and think i understand, then look here and get overwhelmed. Is there somewhere i can look to see simple codes, to try just to see how/what they do, when i add or change something.
Also, do you type all of what is on your codes every time, ex. pbasic, stamp1, constants, main, variables, so on, or is it a template?

You can't hurt the controller writing bad code -- unless that "bad" code is directing pins that are supposed to be inputs to become outputs; that can present a problem.  We have some protections on the board, but they won't cover everything.  Just be careful in your code, and if you're unsure, post it (and the connections) here for review.

ok, thanks, do you type in all the dashes and all the other stuff or just the code itself?

[JonnyMac]

I only typed those dashes once; then I save them into a template that my editor loads up every time do a File >> New operation.  You can find that template in the Library forum under Prop-1: http://www.efx-tek.com/php/smf/index.php?topic=4.0

ok,i see it, i try to read first then ask ? been reading on here all week, so much to learn.

The reason you weren't seeing anything is that you didn't make the output pins outputs -- by default, all I/O is configured as inputs on startup.  There are a couple ways to do this, the easiest (I think) is to configure desired output pins using the DIRS register.  Here's a corrected version of your program:

ok, i haven't tried it but im sure it will work. I've been looking at that, will that (dirs) work every time, or better yet what it it doing?
what is it causing, i know i can't learn all in a day but i want to understand. the other parts i took from here and there to see what would happen

[tj]

i think i got it (Dirs), 00010001  the last 1 is pin 0, 5th from last being pin 4?

[JonnyMac]

Yes.  You can real all about DIRS in the help file; double-click on DIRS in the listing to highlight it and then press the F1 key.
