HATE that program never works for me!So what kind of compilers would you suggest other than BoostC,
I always recommend BoostC. My favorite PIC compiler. It's real easy to use. Be sure to integrate it into MPLAB and use MPLAB rather than the BoostC IDE. Easier that way, IMHO.So what kind of compilers would you suggest other than BoostC,
Did you remember to put #include <system.h> as the first line of your program?Its probably a simple fix, but i am kinda new to it
Thank you.
Hahahaha!

You just did? There's a thing called Add To Reputation at lower left of all posts, if that's what you mean.

, can someone, please convert it to hex for me PLEASE?
You'll have to post your source code. Use Code tags by clicking on the # icon just before pasting.YA, its a NO GO

}Don't be too sure. I might be a lowly worm. I didn't test it.
