Default DF1706 and software mode control?

Hi; I did a search for this but didn't find any info so I was wondering if anyone has done any work on the software mode control for the DF1706. I'm interested in the level control part of it and whats the best micro to use with it.
Thanks

I recommend a PIC with EEPROM to store the volume setting in nonvoltile memory. Just make sure to pick one with SPI support and you probably can't go wrong.

Hi Stu, thanks for the reply, I'll take a look at the pic's. Whats the one you would suggest, micros are not my fortay. What kind of programmer do they require and is there software for writing the program and programing them.

PIC programmers are easy to build yourself. Do a web search for JDM programmer, and you'll find a lot of information. The complete IDE including editors, assemblers, and even simulators is available for free download from the manufacturer, Microchip. They also have a great library of application notes and sample code to help to get you started.

It really depends on the feaure you need, ie. number of I/Os, internal oscillators, A/D convertors etc. How many I/Os do you need?

Hi; Thanks for the replys guys. I'll do a search on the web for more info.

How many I/O's would it need? I'm not sure maybe 6/7 . 2 i/ps for the up/down switches and 3 o/ps for the serial data and maybe add a few extra for good measure I guess

HI; I do have some 8515's which where used for something else, but they are kinda big, 40pin, and are probably overkill for this. My big problem is getting the required data into the proper form to program it with.

If you already know how to program the 8515, I'd recommend the compatible and far smaller (but still DIP) ATmega8. The STK-500 is the best way to program them, and it's less than $100 from Digi-Key. I write my code in an editor, compile it with avra and load it onto the chip with uisp. There is probably equivalent software for Windows or MacOS, if you use those. You should also see http://www.avrfreaks.net/

Nice thing about the AVR is it's built-in SPI port. You don't need to worry about the protocol, it's handled in hardware. Makes banging data into the DIR1706 or the CS8420 a snap.

Hi jwb; Thanks for the info. No I don't know how to program the 8515 either, but I'll learn somehow. I don't recall seeing in the 1706 specs anything about SPI interface?
