Digital Pots in 5.1 System

[till]

If you could send in s/routines for PGA2310 that 'd be good for a start, but what programmer I mean for PIC u use and what the software?

all could be found on my page linked before. http://home.tu-clausthal.de/~tpa/

the sprut brenner 5 i use is linked there, I use MPASMWIN, free assembler from Microchip. Main diffrence between the PIC16F628 and 877A are the number of pins used and the configuration settings.

I ve visited your website, its pretty cool, however perhaps english is not the prefereed language in subroutines etc.
I can help by making PCB as I ahve licensed Protel PCB and Circuit maker 2000, should u need my help drop me an email.
Oh yeah! I would like 2 use PIC16F877 and not 877A.

Hi abdir,

This is especially useful for the micro-perplexed. I am one.

I recently came across a digital pot specifically suited for multichannel control. The Ideas for Design article 'Manually Operated Digital Pot Doesn't Need A Microprocessor' explains the use of Catalyst Semiconductor's Cat5113. The circuit is designed around LM339.

Using the idea, DIYs can redesign using other digital pot ICs.

I do not have the Website. Windows LAN/viruses created problem for my MAC and my browser does not store the links. Any body wants the diagram, please e-mail me.

RE:

Thanks gajanan, I appreciate your help and will definitely loook into the data sheet of the chip.
also a project using PGA2301/CS3310 and PIC16F877 is underway should u need any help regarding that do let me know, at least neighbours could do that.
Thanks again.

The Ideas for Design article 'Manually Operated Digital Pot Doesn't Need A Microprocessor' explains the use of Catalyst Semiconductor's Cat5113. The circuit is designed around LM339.

Kindly read as
The Design Brief 'Use Rotary Potentiometer to Drive Solid State Volume Control" explains the use... ...339

Just trying to help...

Enjoy
