PC/104 Robotics Drivers are Linux kernel drivers
for the ACCES I/O 104-DIO-48S digital I/O board,
Polaroid sonar sensors (up to 8), and an interface
to a PIC controller for DC motor control with
feedback via optical encoders.

The dio48s drivers contain basic input and output functionality to each bit within a defined port. Also, the beginnings of a dummy shared interrupt controller are in place.
