MIP Driver for IO device

Hello, I need to develop MIP driver for IO board with 28 inputs and 28 outputs. I was wonder if there is anything specific for a driver with so much devices(inputs/outputs) or some limitation.

There is no limitation about it so there is no issue on the device with 28 inputs and 28 outputs. You might already know there is a sample called Demo Driver might be helpful for you -

Thank you!
