Hi All,
What a minefield of info on these things out there but try and get just one to tell me exactly what to use to programme the PIC12f683, I am of the impression that all i need is the pickit without the "module" to actually programme the chip but i do need a board to mount the chip on with those removeable chip mounters(i nforgot the name-Zifs or something)that has wires to the 4or5 points that is required to programme the chip(there is a Y/T vid on how to construct one for large sized chips but should work for the smaller pic12 as long as the in/outs are in the same configurations.

The modules and bread boards are for de-bugging? and trial runs on a curcuit, well that is my take on it as the info i have read sofar is very vague to say the least.

If someone knows what they are talking about or cansteer me in the right direction, i would be grateful.

So far i have spent $220 on parts, a little extra was on ordering 1% resistors an extra $16, so i have two sets of resistors and plenty of spares as you usually order in packs of tens.

A Pickit 2 on Ebay will set me back $29 but the module? is an extra $49, do i need both of these and/or do i need more bits to operate these pic 12f683.

It's a bit sad that this is not a working detector that i could take with me and use as a spare detector, how much extra bits and pieces would it take to get this HH2 up to scratch, and if this is set up to learn how programmed chips can be used to help make a detector it certainly is an expensive way to go about it.

It has been said that ..inelab would only have to spend $300 on parts for one of their machines.

Am i missing the point again, please enlighten me before i go any further with this project

It is very easy to spend several hundred dollars on parts when building your own detector. You typically don't build your own detector to save money (unless you intend to build several of them). I've spent well over $500 so far and I'm still working on my detector. But when it is done it will be something that can't be bought anywhere else. Although the first detector will end up costing $500+ the second one will only cost about $100. That's the nature of the game.

As for PIC microcontrollers, you should buy the PICKit2 Starter Kit. It is $49 with the starter board which has a socket for programming. You don't need anything else. I wouldn't buy the eBay unit as I have no idea what you mean by the "module" and you never know what you are going to get. Here is a good source for this part and it has everything you need to get the job done. It even comes with an extra microcontroller. The included board can also be used to program 8 pin devices like the PIC12f683. You can pop out the included microcontroller and pop in your own chip for programming.

You can also buy the PICKit3 but I have no experience with it and it costs more. I've been using the PICKit2 for my project and I couldn't be happier with it. Keep in mind that it is a one time purchase. The next detector you make will cost far less because you will already have all of the "tools" and know how to get the job done. If you intend to build one detector and stop then you should probably just buy a prebuilt detector. If you intend to experiment and build more than one then this is a great way to go.

pickit2

Hi mts,
Thanks for straightening me out i was starting to get cold feet, if like you say we can add and subtract things we can end up with a working machine, something i didn't contemplate probably because i am far from attempting anything like that just yet.

I will hold off for a little while and see what eventuates on the forum as i would only be able to copy someone elses work seeings as i still don't know what most of the parts can actually do.

Again thanks for helping!!
Regards Ron

Pickit2

Hi All,
I was thinking that if i bought a Pickit2 i could make my own board to mount the chip on (PIC12f683) to be able to programme the chip.

Like i havesaid,i saw a vid on Y/T that did this very thing using a board and mounting a ZIF? on it, all he had to do was wire in the circuit from the Pickit2 to the Zif aligning up the right pinouts for the chip to be programmed.

Has anyone tried this or know what it would take to try this out,one day i will understand more for myself and be able to execute these sort of things on my ownbut for now i need a little(or is that a lot)of help in getting this thing operational.

Regards Ron

You can program the '683 directly on the HH2 board. I put a 5-pin header next to it that the Pickit2 should plug directly on.

Yes, you can make your own programming board. And as Carl pointed out, you can even program the devices using "In circuit programming". However, ziff sockets are actually quite expensive. And the simple starter board they give you has a socket on it already as well as the appropriate pin headers. So there is no need to build your own board if you are using a PIC that is 20 pins or less. If you want to use a 28/40 pin PIC (or a surface mount device) then you will have to create your own programming board or add pin headers to your final PCB in order to hook the PICKit2 programmer to it.

When it comes right down to it, you are much better off just buying the PICKit2 starter kit that comes with the programming board for $49. There is no hassle and you don't have to worry about accidentally making the programming board wrong. While you are at it, order a few additional microcontrollers. I've blown two of them so far by accidentally hooking 12 volts up to them. My eyes aren't as good as they used to be and those darn holes on the breadboard are awfully close together.

If you are trying to save some money by making your own programming board then don't bother. It will cost you way more in parts and time than it would to just buy the starter kit.

Good luck.

PicKit 2

Hi Carl,
Would a populated board affect the programming of the pic12f683 or does the programming need to be done on an unpopulated board.

I do have sockets for all my chips just in case i blow them up as i am good at doing this so far!!

Carl, where you said to put a 5pin header i had actually temporarily stuck sockets, i nearly fluked it!!

That just saved me quite a few dollars as i can order the pickit 2 off the ebay for $29 Aussie.

Regards Ron

[Carl-NC]

Yes, you can program the chip in a fully built board. Don't power the board, though; let the programmer power the PIC.

Hi Carl,
Thanks again, looks like i'm sailing along again!!

The socket on my PicIt2 board (02-01831-R1) is not a ZIF socket.

Best place to buy SMT parts?

Anyone have a recommendation for SMT parts. I had a hard time finding parts to build my GoldPic 3. I can imagine the SMT parts for a HH would be even harder.

[gocko]

ah

Can I make this hh3 detector with pic16f877. Somebody see it?

[Carl-NC]

HH3?

[gocko]

Hmmm

hammerhead detector but to create signals like TP1, TP6, TP7 WITH MORE STABILITY AND PRECISION? Somebody have ideas how,because 16F877 have just TWO PWM outputs RC1 RC2 ?

[gocko]

which resistor need to be with logaritmic scale R35 or R41 for better results ?
I will connect in serial R41(5k) 220 Ohms resistor because my speaker is
8 ohms.
