That should be no problem.
If you did it like that and nothing else connected to the chip, it must programm it.
There is ofcource still another possibility!
The porgramm you wrote, sucks!
The rest of your connection and or powersupply is not good.
Sorry for this language but at this moment nothing else came to my memory.

It was a simple blink circuit and my power supply is a fixed bench top power supply
I believe I just have a bad programmer because the programmer would say it reads a device and then say it didn't
I say I should just move on to an Arduino

That's a choice, but it doesn't have to be an this <b>or </b> that choice. The PICKit2 will supply the chip and some simple circuits without an external power supply, it is a bit fussy about short circuits though. If you short it out you will have to unplug it and restart the software. Since you have the PICKit2 already, why not order the low parts count demo board and eliminate all the fussing with wires and breadboards to prove out code snippets, which you can translate over to other chips later, the 16F690 is a pretty powerful chip and the demo board couldn't be easier even if it had an Italian name. And trust me, PBP beats the heck out of all that screwy syntax the " C " languages use!Originally Posted by Techbuilder

What if my PICkit 2 is just the burnt cookie of the batch
which would mean I would have to purchase the development board and a new pic kit
honestly I love basic but I have not been able to find a way to properly compile and program to a chip
This has been my second programmer
1st one I bought was on ebay
it was a Chinese made board

PIC16F627 has a PGM pin, and can work on LVP mode. Having the LVP mode set to off in your config fuses is not enough in many occasion, you also need to pull this pin to gnd with a resistor.
See the following link
http://www.microengineeringlabs.com/support/icsp.htm
And see what note 4 says...
Also make sure of your connection, As far as I remember, Pin 1 of PICKIT 2 is the pin with the white arrow on.4. Make sure the "low-voltage programming" pin is pulled to ground. Low-voltage programming is not used by melabs programmers and should always be disabled in the configuration settings. Even so, the low-voltage programming pin (labeled PGM or LVP) should be pulled to ground when programming. If it is left floating or in a high condition, it may interfere with the programming process. ...

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

I have 3 programmers, 2 $8.00 JDMs and a PICKIT2, I have Smoked a few PICS, and A nice Sure Electronics dot matrix board, but never a programmer. Is the USB port you are using working for other devices?
Maybe you should UnInstall the Software and reinstall it. The Low parts Demo board is pretty cheap, and plugs into the PICKit2. http://www.microchipdirect.com/produ...rds=DM164120-1
I just love it!

I face the same problem with PIC Kit2
Hi joe,
I just buy a PIC kit and try to program my development board..I manage to program the PIC using PIC Kit 2, but led is not going to blink..this is my code:
DEFINE OSC 20
LED VAR PORTC.5
trisc = $00
MAIN:
HIGH LED
PAUSE 500
LOW LED
PAUSE 500
GOTO MAIN
maybe there are mistakes in the code? For your information i use the code to program PIC16F877A. Communication from the PIC Kit 2 to my board is ok..and programmed successfully.
I have another question. I let say my oscillator did not work, is it the programming stage failed? because I not check the oscillator yet using scope.

Hi rosmadi,
Welcome to the forum !
Second question first: If no ocsillator, Then no work. period. If the configs are incorrect, then no OSC.
Your code looks as if it will work, <b>BUT</B> You did not list which PIC you are using, If you are using the development board or a solder less breadboard, and how you are powering it, either by a separate power supply or from the PICKit2.
The PICKit2 window has a little check box to power the development boards. Please give us the missing information I am going to list.
PIC number
Assembler . . . MPASM or the automatic default as installed
Development board ? or Breadboard?
Have you changed the xxx.inc file yet? xxx meaning the pic number I. E. 16F690.inc ? you will need to do this if you want to put configs into your code (recommended).

The 3 threads are <b>must know</b> information to successfully program PICs.
