Have you tried using the extended I/O configuration for the Cypress Board? Doing so will get you half way there, in that you can manually set each of the digital pins direction (and if you set it to input, you can also set whether you have a pull up, a pull down, or leave it floating).

The way the communication is architected, the analog inputs are updated just as often as the digital inputs, so making them digital inputs won't make them any faster for your purposes.

Also, may I ask what you are doing that requires speed? The extended I/O has a few neat features that may help you out here.

*I assume you mean for use at the Driver Station. If you intend to use the board on the robot, ignore everything I said: You can do whatever you want (within the rules) on the robot.
