I am a newbie and am having trouble starting

[Iawia]

(I have read through the faq, and did a search on my error as not to repost a question that has been answered already 1000 times but have not found an answer, so i turn to you..)

I purchased the Pickit 2 Starter Kit from Microchip about a week ago, trying to get a foothold on this new world of microcontrollers, but I am getting very frustrated because I am not able to write to my target. My code builds and everything, but when I try to write to the target i get the error:


Programming Target (10/21/2011 9:20:26 PM)
PK2Error0049: VPP Voltage error. Check target and retry operation.
PICkit 2 Ready


I ran through one of the tutorials (hello world) and was able to successfully program a P16F690 chip (light an led). I changed the chip and the code to reflect the changes.

I am running windows xp, am using a p10F200 chip, and am using the latest MPLAB IDE v8.80. Why would I suddenly get a voltage error? Can anyone help me???

attached is the code i am using (to simply light an led).

Can you post a schematic of how the 10F200 is wired? It sounds like you have the MCLR pin wired wrong.

From your description, it sounds like you may have the PICkit2 + Low Pin Count Demo Board bundle (DV164120 - PICkit 2 Starter Kit)
If that is the case, it's impossible to use the PIC10F DIP package in the 8-pin section of the socket, due to the irregular pinout of these devices.
You need to consult the PIC10F datasheet and make a DIY adapter, or use a breadboard & some jumper wires to match up the 10F pinout to that of the 12F's:

PIC12F675
1 - VDD
2 - GP5 (NOT USED)
3 - GP4 (NOT USED)
4 - MCLR
5 - GP2 (NOT USED)
6 - ICSPCLK
7 - ICSPDAT
8 - VSS

PIC10F200
1 - NC
2 - VDD
3 - GP2 (NOT USED)
4 - ICSPCLK
5 - ICSPDAT
6 - NC
7 - VSS
8 - MCLR

you must be correct. thanks for your response!
