Does anyone know of an electronic volume control chip that can be interfaced to a BS2? Thanks

Pretty much any digital potentiometer can be interfaced to a BS2. The SPI (3 or 4 wire versions) are the easiest. The I2C (2 wire) are easy with a BS2p/pe/px, but can be interfaced to a BS2 using a subroutine rather than a built-in statement. There are some other ones designed for use with switches (up/down) that can also be interfaced using HIGH/LOW or PULSOUT. Check the Maxim/Dallas website for datasheets and selection guides.

If you want a device specifically designed as a volume control, the answer is "probably yes". It depends on which part you want to use and how it works.

The following thread covers a couple of stereo volume control IC’s which can be controlled with a BASIC Stamp. Take care.
