e) Rotary Encoder
The Panel-Card EVB includes a rotary encoder with push-button which is a "Human Interface Device"
well suited for many embedded applications. Generally spoken, it is a simplified replacement for a
computer mouse, touch pad, or keyboard. The rotary encoder represents a pointing device with only
one dimension, while the push-button serves as a "return" key or mouse button.
The rotary encoder is accessed by two PIO ports of the Stamp9261 (see circuit diagram). The push-
button occupies another PIO port.
