Simple Blink program doesnt work.

Ok, thats worked. Disecting it found that it was the MCLRE that made the difference. I'll read up on that as it is the only part of your explanation that I didnt understand. It seems that there are a lot of things that I need to learn in this area that were not needed with other chips. The frustration in the past with these pics may have been what pushed me to Basic Stamps, but their cost eventually pushed me to the Picaxe's. However, their inability to accomplish certain things and much lower availability to US customers has brought me back to this. I guess I need to fight my way though it this time.


Thanks for your help mackrackit.

I had similar frustrations when I ported from the Basic Stamps to the PICs. I found the most important thing was getting the PIC setup correctly for your application A/D, digital I/O and config bits. I printed up the data sheet for the 12F675 and left it in my library (bathroom) and read it through and through. This realy helped as I moved to other PICs as I knew what to look for (A/D, PWM, digital I/O etc) Its intresting that the masters sometimes dont show the config and setup info when they post there help code. Get a "Hello World" (blinking LED) working on a new PIC before you proceed any further on a new project. Best of luck, and keep on nearding (what my wife calls my obsession)

Look at the chips Data Sheet for which pin is used with MCLRE. That pin must have a pullup resistor if MCLRE is enabled in the config statement.
<br> Rather than changing the config statement in the .inc file each time I would insert a semicolon just before the first letter in the statement and insert the statement at the beginning of my code, every time.
