I would like to build a board with 16 inputs and 16 outputs. I would like to make all of the inputs and outputs analogue. I would like to utilize PID control. 10 bit AD would be preferred. Does anyone know what hardware platform might be good

    Geojr,

    Using multiplexing, you can easily get the number of inputs you want. The big question is what kind of analog output do you need? If you need 10-bit resolution on the output for a voltage output, you'll have some arrangement of d/a chips there as well.

    PID loops take processing time. It will be a trade off on processor time versus how fast you need to update the outputs after an input scan.

    If you can give us a few more details, I'm sure you'll get a clearer answer.

    Cheers,
