I'am having a trouble connecting the AD 667 to a pic microcontroller, do i connect all the inputs to the pic or the cs and A3-A0 pins only ?

I'm sending a 16-bit data word from the PIC 16f877A to the AD667, only this data is in the Timer1 register wich we can have access to from one pin , and i really don't know how to send it to the DAC

    Hi,

    Not an expert but internally in the microcontroller, you can utilize different peripherals(e.g. comparator)  to achieve this, you can ask the manufacturer of your microcontroller.

    If you want to use a DAC, the choice of parallel and SPI interface is really dependent on the update rate you want to achieve and the simplicity of the solution. And, do you have enough GPIOs for parallel communication in your microcontroller?

    Cheers,

    Ivan
