    ======================
    Hi Sayzer,

    MCP4921 is using SPI instead of I2C. I tought I2C, which I'm currently using, was easier than SPI because PBP has I2CREAD and I2CWRITE commands. I saw example of SPI slave & master on melabs website, but I can't see why you said MCP4921 was easier. Can you elaborate?
