lol.... Not a damn thing. Not 1 pin goes high.
I have a few of these chips ordered at different times so the likely hood of all of them being bad is not very likely.
Edited:
I took out my "DEFINE OSC 8" and no Porta.6 goes high but is not blinking. So I guess it's still "nothing happens"..................

Kinda rules out bad port settings eh?Originally Posted by plyrathrt
What are you using for an oscillator? A crystal? A resonator? External clock input?
Got a pull up on MCLR?
|
Internal, packaged in to the chip.
You only need to pull up the MCLR for Programming... Also keep in mind, this is on a full development board (Mikroelectronica EasyPIC 5) and not just placed in a breadboard with ICSP.

Ok, here's the next question....and it's going to be a tough one, I mean hard...You may have to study quite awhile to answer this one...
Which internal clock would that be on the PIC16F870?
(Ref: Pic16F870 datasheet, DS30569B-page 89)

I don't see anything about a software selectable internal oscillator. I am guessing that is why you said "you may have to study very hard". Is that correct?
Even with that it should still turn a pin high that I designate for a button press right?
|
Not without some sort of oscillator driving the chip you won't...The PIC16F870 doesn't have an internal oscillator...Therefore, your chip won't run anything.
Did you see the 4 oscillator/clock options you have with the PIC16F870?

Yes I did, however for my project I must have a internal oscillator due to size constraints... Ok, so basicly I am the idiot and I should take a hammer to my head instead of the chip... I don't know why I assumed it had a internal oscillator other than the fact that I have never used mid-range MCU's. Only 16pin and smaller PIC's.
Know of a 28pin PIC with a accurate internal oscillator off the top of your head?
