PICKINI V4 - an easy to build, self adjusting PI detector

[eclipse]

Download the Pickit software. For Example (don't know if there's a new version, after installing try to update):

Okay, I got my pickit 3 today. Downloaded MPLAB v8.92. It was a zip file. Eventually and tentatively I unzipped it and double-clicked the Setup wizard. I have installed it, but unsure if I did this properly. Got shortcuts and windows, usb recognises pickit unit. But all the files from the zip are still in downloads. Can anyone tell me where they should be, or if the install will have put them(copies) where they should be?
What do I do next?
I searched for hours online, and nothing back to these basics, and the rest is gobbledigook. I have 3 PDF versions of instructions-all mean nothing to me. Much talks about de-bugging, and all I want to do is program the bloody chip. But I have no idea where to start.
Any advice greatly appreciated- no acronyms please.

?
Did you buy an ICSP as well

This is the kit I got 6666. Correct me if I'm wrong, but J1 jumper needs to be across position2 for 16F's ? Bloody confusing, as the destructions say positionB (ABC not 123).
Jumpers J2-J7 are in place.
Thanks eclipse, going back there for a look now. Is that MPLAB IDE 8.92 thingy something separate to the 20v3.10 thing, or just a latest version of it?
I had to plug the pickit into usb port to get the download to complete, so I presume it updated then- the lights were flashing..
Unsurprisingly all the online tutorials I have found presume I already know about programming.....

[Tim]

Ok that 3.10 thingy has exe and an msi. I need to take the files out of the zip? to where? then what? The MPLAB IDE 8.92 had 5 files-mplabcert,ISSetup.dll,Data1,MPLABtools v8.93, and setup(launcher) the latter was the one I successfully ran from downloads file. They are all still there...
I have the MPLAB IDE v8.92 successfully installed..I think. Opens to a screen when I click on the shortcut. As my compooter has limited usb ports, I can't be online and open it at the same time, as I need to safely remove hardware - the pre-paid thingamebob- before I can plug the pickit3 in...

Seems a step-by-step to install for dummies, and a step-by-step to program a 16F1824 chip is going to be a big ask...
AAARRRRGGGHHH!!!!!!!

[6666]

Do you have a schematic for the icsp ?
programming with mplab is easy and only takes a few steps, one of the important ones is to turn on the 5v power in the menu
however the icsp needs to have correct jumpers as well, I have an icsp similar to yours which I dont use
but it came with a cct to get the jumpers right, google the chip you want to program and you will see what pins are required.
a 16F1824 is 14 pins so icsp has to be wired for a 14 pin pic. you can check with mutlimeter,
take notice of the white triangle on the pickit. thats pin1 VPP, mplab should start from shortcut and talk to icsp, but you have to select it in hardware

Ah I think the little drawing on the right side of the icsp is showing the notch in the chip and the chip should be inserted at that point in the icsp
check with a meter.

7chips go in one direction and 1 chip goes in the other way round

so if thats correct, plug the 1824 into the pin thats says 8/14/18/20

[Tim]

Very good 6666 8/14/18/20, yes, I was wrong thinking the 16F57 position. I will check before powering up, but I am afraid I have much to learn blindly...So , it's after midnight here now. Tomorrow I will position and check the chip in the icsp-I have the lead worked out-plug it in, fire it up, and see what screens come up.
Baby steps, but in the right direction. Thanks matey.

Hello Nick Holas

please check your Sprint Layout Settings, look pictures attached
risk of damage, caused by Thermal Pad connection



@ Tim
look at bottom side
there is diagram
it say for dip8/14
set jumper 1 to pos. B
jumper 2 to pos. 2+3
jumper 3 to pos. 2+3

place chip as shown on bottom
i have ordered same socket, at first i looked like a pig in the clockwork, because it searched some resistor or so
but this thing it realy easy and it work also for pic16f876

[nick holas]

Hi Bernt
Thanks a lot
I havent sée that
Another mistake a made i go too fast when i modify pcb!!!!!
Finishing my rod shaft
thanks again

[6666]

I have made some pictures to try and help, buzz with meter before you plug into laptop
if all buzz's ok
the chip i think should plug in where shown you will get the idea
next connect the ribbon cable so vpp lines up with say the blue wire on pickit and iscp, thats matching the white triangle
the ribbon cable only plugs in 2 ways

if it buzz's ok next plug the pickit cable into usb

start mplab I use v8.76
in configure select chip
in programmer select pickit
then in programmer - then settings select power and tick "power target circuit"
at this point you may get a message saying that some software needs to be downloaded to pickit, select yes
if all is well you should see an ID come back from chip in OUTPUT WINDOW
now go to file, then import and navigate to folder where you have the hex file, select the file
on the right of the top line of program you will see 7-8 little symbols, as you move your mouse over each one it will tell you the function of each one
such as program and erase

I always erase the chip first

so hit erase
you should see some actiivity in the OUTPUT screen window
if all good chip should erase

then hit program, you should see some activity in the OUTPUT screen window

if all good you should get a message saying done or complete something like that
hope this helps and I have it all correct good luck

[Tim]

Great help thanks 6666. That is a very helpful format of instruction for me. Very much appreciated. Hopefully I will get to it later today.

Thanks Bernte- I didn't even look at that. Yes, mine too has the outlines and tracings on the back, and I now notice about A/B positions on J2-J7.

Thank you both very much!

I have been using a simple 8 pin socket on a piece of breadboard as the interface to the PICKit3 for years now, with different sorts of PICs.
The 8 pin devices simply go into the socket, the 14 pin devices have their top 8 pins inserted - pin 1 = VCC and pin 14 = GND.



Pinout to the PICKit 3 controller ( with pin 1 of PICKit = triangle )

PICKit --------- socket
1 -------------->4
2 -------------->1
3--------------->8
4--------------->7
5 -------------->6
6 NC

[F117]

Needless to say, this contraption needs a new IC socket now and again...
The LED is just an indication that power is provided from the PICKit programmer.

I made a short video in 2 parts:

1. Pickini V4 swinging over a heavily mineralized rock from our garden ( a stepping stone, or something like that... ). A normal induction balance detector like my XP GoldmaxxPower will detect the rock and give a clear signal. Since Pickini V4 is a PI detector, it does not detect the rock. You should only hear the idle "tick" sound at 1Hz. Unfortunately, my video skills are very limited. I hooked up a small loudspeaker to the headphone jack to pick up the sound with my digital camera, but it is heardly audible.

2. A 10 Eurocent coin is placed on top of the rock. Pickini V4 detects it. The detection sound is also audible when you crank up the volume.
Then, the pinpoint button is pushed and the coil hovers over the rock, detecting the coin continuously ( no motion mode ).

With my apologies for the amateuristic video. I tried to upload it to youtube, but after logging in, I got a constant error :
Sorry, an unexpected error has occurred. Please try again later.

I tried "later" a couple of times, but it didn't work.

Instead, I placed the small footprint video on my own web space:

Cant open the video
In few days the ic will arrive, looking forward to this
