The PIC Micros were programmed with Willem programmer - but you could use also JDM programmer which is very simple for DIY. The code was writen in Pic Basic Pro language. The code is not complicated - I have corrected the code which I foud here on the forum because it was written for 16F84 PicMicro. The code for the input selector was also writen in PBP.

Here is the main code :

hi

Excellent, thank you for the code. I will likely disect this for my own project if you don't mind. I'm planning on using either two 16F88's of A single 16F877A. I will have a few more ins and outs but that should be a simple matter to deal with.

Thanks Again!

Hello

I wrote this code months ago, any way good work you done bostjancek. You worked that alone, thats really nice

If any one needs a programmed PIC16F84A to which I originally wrote this code, and PIC12F675 for signal selector, or PIC16F628A for the volume control part, then I can send it programmed and tested PIC16F628A --> 7.5$ --> PIC + shipping fees. Shippings fees may not exceed 2 to 3$, so don't worry about that. I will see if I can supply PIC12F675 for a lower price. I will try to find another supplier for PIC16F628A, I think it will be for 6.5$ if I find it there....

Aslo if any one needs personal specific changes to this code, I can make them for him as fast as possible, and send him the programmed PIC16F628A.

Good luck.

Hello metal ! Yes the code in mine main controller is based on your code - you've made the code so clear that enyone could do some modification to feed it's own needs. Thanks !

Just my 2 cent, I think it vould be better to use just 1 PicMicro for main controller + source selector. The 16F76 or 16F873 or 16F876 vould do the job.

Thanks again !

Cheers

nice craftsman ship in building the casing, and equally good thing to have shared your code which is based upon one which was shared by metal months ago, however, a serious suggestion, if this is the final version of your amp then its alright, however if you plan to revise it in the future, then it would have been better that you had posted your schematics here so that others could see and possibly suggest improvements in the circuit.
Anyways cheers man for building such a good preamp and congrats for doing it alone.
Oh "sss" for preprogrammed PIC I suggest you to contact metal, he has done it earlier and i think he would have improved on that.

Hello

I saw the same project in one of elektor issues, I don't remember which one, but if I find it, I will scan it and upload. The code was written using a compiler that I don't know its name in deed. I emailed elektor in order to know which compiler was used, but had no replies !!

I'm also very interested in seeing the rest of the project documentation if anyone is able to find it.
The published performance is exceptional.
I may have to reconsider my planned moving fader attenuator!

Cheers,
Ralph.
