MCP3302 or MCP3304 (4ch, 13bit ADC) experience?

Does anyone have any experience using the MCP3302 or MCP3304 with the BS2? It's looks like a good 4-channel 13-bit ADC with SPI interface for a good price, and was wondering if it's similar to the LTC1298, only with more channels, more resolution, and lower price.

    I'm new to this forum.· I'm also interested in the MCP3302, expecially any· C code examples of using this chip.

    Thanks!!!!!!!!

    The Parallax Basic Stamps can only be programmed in Basic, not in C, so C code examples would not be very useful in this forum.

    The datasheet for these parts indicates that a minimum clock rate of 105KHz is required during conversion for proper conversion. None of the BS2 modules can provide that. You'd have to use an SX or Propeller in assembly language. It wouldn't be difficult, but it's probably not what you want.
