Not sure how many people have the NSDSP programmer yet, other than Evan, but I have a question...
I have switched from the pickit 3 to the NSDSP-1-U, which is the "universal" programmer. I set everything up and all is well except now that I am using #config LVP = ON, nothing else has changed, my circuit continues to reset. I do have something hooked up to the MCLR pin, which in my program is used as in input. When using the pickit 3, this seems to work just fine. I tried using #config MCLRE = OFF and WDT = OFF just in case, but seems to make no difference, circuit keeps resetting. I moved the input to another pin and left MCLR floating and that did the trick.
I am not programming the PIC in circuit. I have the NSDSP connected to a little board that has a ZIF socket, so I am taking the PIC off the breadboard and placing it in the ZIF, programming it and re-installing it on the breadboard. Again, this all works fine using pickit3, just FYI.
I am using a pic12f1840 and latest GCB setup. I was lucky to have one spare pin on this circuit, but does using LVP disable the use of MCLR as an input or am I doing something wrong (first time using LVP)?
I have to say, THIS THING IS FAST! Programming and verifying in 0.375 seconds. Not sure how they did it, but holy smokes...
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Sections of the datasheet reads "While in Low-Voltage ICSP mode, MCLR is always enabled, regardless of the MCLRE bit, and the RE3 pin can no longer be used as a general purpose input."
And, fast! Blindlly fast.
And, easy to use.

Thanks for that info. Bummer, but I will live. Thank goodness for that last unused pin. Super happy with this thing and its speed. Set up the flashpic.bat to use it and it works sooooo well. I purchased a couple of the 5v and 3.3v chips also, so can't wait to try them on a couple of projects.

This does look interesting, if a tad expensive. I'm almost tempted to order some of the individual chips and 'roll my own' programmer just to give it a go.

See http://www.northernsoftware.com/nsdsp/conn.htm and your finding are the same as mine.
