@ Lougous

What's so interesting about this Preamp...? It's just the standard application without any buffers...

Have alook at this:

A modular system with touch screen... OPA134 at the input and OPA134+BUF634 at the output...

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,

I am searching this project from long time.
I am not much famaliar with microcontrollers. So would you be kind enough to post the hex codes and schematics 😱.

BTW does your circuit has provision to store the last volume level used.

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 !!

It’s compiler is Jal and the links are available on page of the person who made the project developer.
