I'm almost a complete newbie when it comes to PIC chips (although I did read a book on the subject around three years ago).
I've got a JDM serial programmer. Will this be sufficient to program PICs for the decoders?
And can anyone recommend any software for the task?
Many thanks,
Tony.

Microchip has a free program "PICkit2" on their site. I think it works with JDM. I think if you have problems programming a Pic it usually is because the port from the computer isnt putting out enough voltage. Laptops mostly.

I invested in a Pickit2 in the end (I think that's what it is). No problems at all programming with that.

I am not familiar with the JDM programmer, but I just did a little research and all the ones I can find appear to be only for 18-pin PICs and not for the low pin count family (8-pin, 14-pin and 20-pin).
My experience with trying to program the low pin count family of PICs with similar simple programmers was that it is not possible to do it reliably, they are much more fussy about voltage levels and timing and require a proper programmer like a PICkit2. I found that WinPICprog was the best software for the simple programmers, but it still was not very good.
You can get a PICkit 2 for less than £10 on a good day so it really is not worth messing about with the simple types.

Hello,
My name is Aleksandar and I want to make one mobile decoder for testing with 12f629, where I can find HEX for it?

The firmware is on the download page of the main DCCDIY website:- dccdiy.org.uk |

Oh, yes, thanks
Anybody have some add. advice ofr this decoder with 12F629
Is somewhere mobile decoder with 16F628 without egzotic parts like MERG, BUT with many CV?

The most exotic part in the MERG is the 16F628! It is a big 18-pin chip.
If you are keen you should be able to port most of the MERG code into a 12F683 or 16F684 and use it in the DIY Decoder without BEMF. The MERG code should have better performance.
