Re: PICKIT 2 Clone Error
Ill check the Hardware again. Here goes the trouble shooting process .... :|
As i said earlier, the Vdd is usually 4.43 volts, but PICKIT2 software says it might be too low to calibarate. Ill check Vpp...
Re: PICKIT 2 Clone Error
^ thanks spiral. I'll replace the 4148 and see how it goes. iM pretty much sure the transistors and caps are in order as per the schematic. Ill be taking sometime though. Ill revert back to you guys when the replace emtn is done. meanwhile can someone let me know is...
Re: PICKIT 2 Clone Error
Thanks for the reply guys. Only two substitutions were made. I ran out of BC548's so switched to BC547's but got the pinouts correct. Insted of a !N5817, I switched to a 1n4148.
Voltage check with DMM (W.r.t gnd) :
VPP : 3.94 V
VDD : 5.10 V
The Voltage I get while...
Re: PICKIT 2 Clone Error
Yes. I connected a PIC 16f628 and 16f84a directly on a breadboard after verifying pin outputs. I plan to make a ZIF socket if this works.

Hello All,
I managed to replicate this programmer, **broken link removed**. I programmed the 18F2550 with the latest firmware and the device is detected fine. I tried Programming a 16f628a and 16f84a today without applying any external power. the programmer for Microchip does not detect the PIC...
Thanks all, found a better solution somewhere else :???: , mods can lock up this thread now. Frankly speaking the solutions were either a overkill or not what i really expected. but a huge relief was that none of the Board sellers advertised on this thread.... phew
Ok John, Ill look at yours. but still think something can be done with the power derived from the USB board. Can you tell me what kind of problems you faced?
Thanks for the Suggestion Brian. In fact,I saw the Design from yet another Member , Nishal. Although the Kit looks good, I'm still considering other options mainly beaacuse I want to keep it simple for the students.
Hope you get the point.

@ john : Sounds like a good idea. I saw A schematic from blurroomelectronics. It seems quite simple but no support for 3.3v devices. I might attempt that. But then again, Im trying hard to find a device which can support 3.3v Devices as well.
Hi!
@ Brian: Yes agreed that the PICKIT2/3 is a much better option for a microcontroller enthusiast, but for very occasional programming, i dont really see the point in buying a 40$ + Shipping programmer to India, that too in a bulk (10 plus minimum) quantity.
I Hope you realise that as a...
Hello Everyone!
I'm New to EDA boards. I'll make a Quick OT Intro, I'm Ragav, a Radio Amateur, from Chennai, India. I'm Mostly into Software Defined radio's and RF circuits by default.
For a Few days however I've been reading up on Microcontroller projects and would love to get my hands on...
Hi there Pranam!
I was wondering if the programmer layout in the link you've provided has under board jumpers? The BRD file is Different from the PCB layout given in the PDF file. Can you just confirm this or is the late hours really getting to me? If possible can you also provide a component...
