Have a look at the pickit2 on Microchip.
It is very cheap.
You can find schematics, firmware and software, source code for the whole thing on Microchip.

Has anybody built this pickit 2 design? I don't remember where I got it. I think it may be elsewhere in this forum. It has no op-amp, bipolar transistors instead of mosfet's, and through-hole components. A quite simple design, but appears to be fully functional compared to the original. If someone has built this or knows whose des

I drew the original schematic for the pickit 2 into Eagle using all through-hole components. I substituted the dual MOSFET with discrites, and replaced the op-amp with a through hole version. All of the other parts are identical to the original (just through-hole).
The problem is when I built the circuit, the device connects an

The best route to follow is to buy a pickit2 and develop from mplab. Its not everyone's favourite but it works and has a good help system.
The alternative is to get a schematic for the pickit and build it yourself but if it fails to work you will not know where the problem lies.
Old programmers like the JDM also work but serial ports are (...)

1. The programmer itself is powered from USB. That target device must be supplied from its own power supply during programming, since this programmer circuit cannot provide power to the target.
2. C1,2 - yes, either should be good. C4 - yes. C5 - Usually that would be 220nF (nanofarad) for Vusb, although the original pickit 2 uses 470nF. Not

Go to Microchip and download and install the latest version of the pickit2 software.
If you run the software and do Help, readme, you will find a list of the chips it supports. It does support the Pic16F84, allthough this chip is a little dated now and expensive, not recomended for new designs.
The pickit2 is a nice bit of kit and supports lots

You can use pickit 2 to program dsPIC30Fs, we have use it without issue.
However keep in mind those dsPIC30Fs are so power hungry (especially running in high frequency), you better use external power supply than supply power from pickit 2.

You didn't tell, in which programming adapter you have found the said strange circuit. I can only say, that common PIC programming
adapters, e.g. from Microchip, are using a filtered and stabilized VPP voltage source. You can refer to the pickit 2 schematic, that
has been published from Microchip, or serious third party designs.

The Blueroom version of the pickit2 "Lite" is well proven so no worries there.
D2 supplies the Targets +5v if the target is not powered.
Its important to use that type of diode as it only has a voltage drop of 0.2v.
Yup. The 5V will be supplied by the USB line.
it would appear that the diode would be shorted by the usb 5

Just download the source code (written in C) for the pickit2 from the site of microchip. Open it in MPLAB and recompile it for the 18F4550. The pickit2 schematics are available, or use a simplified schematic.

Have you set 5V to on if you are using MPLAB or pickit 2 standalone software? The software by default will pull MCLR low. thus, your PIC will keep reseting.
