I've been looking at that ebay site and the pictures of the PICkit 3 and the PICkit 2 are identical I wonder whether it's a PICkit 2 in disguise. Have you tried MPlab and running it as PICkit 2 ?




Mick

Also try connecting via a powered USB hub ... not direct to PC ... some PK3s need more juice.

Thank you moodz
I have tried the first two ideas no joy
so downloading ver 8.3
and will give that a try
much appreciated

Try connecting the PICkit 3 to a board with a chip to be programmed on it.
OR
You could try the following procedure ...
Run MPLAB then hold the button on the unit, and while holding, plug into the USB. This will reload the firmware however I am not sure it will work for clones.

OR try this .... from a Microchip thread...

1 - Open MPLAB 8.3 or 8.36 - I'm not really sure why, but it is this one that has PK3FW_012505.jam firmware and select PK3 programmer (Programmer -> Select Programmer);
2 - Connect PICkit3, you'll get the error 38 or so, stating that PIC is not connected;
3 - Press the button on PK3, until the blue Active light starts blinking;
4 - Go to Programmer -> Settings -> Configuration and press the Manual Download button;
5 - Choose PK3FW_012505.jam firmware and press Open;

Sorry to hijack your thread
been trying to get the pc to talk to the pickit 3
with mplab.

Seems to be a plug and play setup
plug in the pickit3 to usb port
start up mplab and select programmer or debugger (pickit3)
but keep getting this error message

PICkit 3 detected
Connecting to PICkit 3...
PK3Err0038: Failed to initialize PICkit 3.

Has anybody else got one of these pickit3 clones to work ?
there does not seem to be any other settings to pick from
thanks

Thanks moodz and dave
mine came with no software
it is supposed to work with mplab I have version 8.76
you need a version above 8.2

the handbook for this pickit 3 is at

http://www.sure-electronics.net/download/index.php?name=DB-DP005&type=0

just click the word download

trying to get the pc to talk to it
cheers

and the LCD arrived in the mail

I received my Pickit2 Clone today from Sure Electronics. It did not come w/software. I downloaded the MPLAB C Compiler from here: http://www.microchip.com/stellent/id...cName=en536656

If you are only burning the hex files and want to use the inbuilt UART tool ( serial comms ) to talk to the UNIP chip ( saves wiring up an LCD ) get the pickit software here ....

I am one step closer, pickit3 arrived today, nice little unit
now for the other goodies.

Hi Moodz,

You said in your last post" how would you know if the damping is set right, out in the field", from my experimenting the correct damping of a coil gave maximum depth to a test piece.

Maybe someone could confirm this!!!

Regards Ron

Hi Ron ... on most PIs the damping is not really a user control ...its kind of a bench setting ...in this design the damping is a user control and is actually critical for the unicoil design ...as you can't set the descrimination without it. The depth will depend on the damping but also sample timing amp gains and even threshold settings in the audio section.

....now we move into the overtaking lane.

A new menu item has been added to the UNIPI chip. User settable damping
It is usually not practical to set damping in the field ... The UNIPI can do it now ... select from menu and adjust for minimum signal using AIR ( ie coil not near ground ) .... or you could adjust it with the coil near the ground ( AIR + GROUND ) ... who cares ... do whatever you want .... its easy

Below we see shots of OVER, UNDER and OK damping. Below that is the LCD menu displaying the "goldilocks" setting.

... some may ask ... but how will I know if the damping is set right in the field without a CRO ???? ..... well if you look at the pics below and lets say you were sampling at about 7 microseconds ( he he ... oh you noticed my nice coil speed did you ) the output of the preamp will either rail positive or negative depending on over damp or underdamp and this is what indicates by way of a very simple measurement whether you are under or overdamped.

Anyway ... if anyone is interested I could add some code to "autodamp" the coil which was going to be a feature on the UNIPI PRO but what the heck ... we can do it on this chip also.

These results were tested on a monocoil front end. This is the descriminating frontend that not only descriminates but also provides faster damping through elimination of parasitic capacitance ( sure to be a future topic of furious debate ). I have the circuit physically laid out for testing .. but I have not drawn it yet. The code on its own wont damp anything ..... so I will release it when the hardware drawings available and maybe a bit more testing on coil speeds etc.
