PIC Microcontrollers

Has anyone used a PIC before? I am building a circuit using a PIC30f2010 but can't program the IC. I got given an programmer from a Ph.D student who said he uses it all the time but I can't get it to work. Mainly I can't find a program that works. I'm willing to build my own programmer if I have to but does anyone have any success with a programmer and uploader for the 30F series?

nope, used 16f84 or 12cxx series, is it a new device ? what clock are you using ?

How does the programmer connect to the system? If it's via a parallel port you may need one of the various drivers that lets programs do direct I/O accesses in order to get it to work.

I got it working now. I think what you said Ex was the problem.

Another related question. Now I can't program the thing properly. Im just trying to test outputs by telling the PIC to output either high or low on certain ports. The code I'm using is this:

Code: Select all

#include "p30f2010.h"
 int counter;
 int main(void)
 {

	TRISD = 0x0000;
	
	while(1){
		PORTD = 1;
	}	 
}

To me this should put 5V on PORTB0 or on 1-5 if its active low. I've tried other hex numbers but none results on any port giving 5V. I just using the MPLAB V7.5 to to write the program in and use with the MPLAB C30 compiler.

I would also be helpful is someone knows a PIC for beginners site that has good tuts. Once I can produce outputs though I should be right.

there should me emulators you can use to simulate what's happening.
Maybe you've got a watchdog trouble, or the port is configured as input.
