PR-1000 Rotary Encoder System Architecture
[Click for larger image]
The PR-1000 uses a position sensor (digital encoder), brake, microprocessor,
and amplifier to provide response characteristics that can remain stable
over the life of the product. A push-to-select switch can provide input
for parameter or mode selection.
Immersion Studio® for PR-1000 developer
software can be used to define the best profile for the context of operation,
which can then be embedded in your user interface application. The PR-1000
rotary encoder has a 5.0 volt serial interface optimized for embedded
control systems. It is completely host-controlled, losing profile parameters
when powered down and retaining profile parameters until it receives new
ones.
At runtime, as the user interacts with the encoder and its position changes,
the embedded microprocessor interprets this action and initiates profile
characteristics by sending control signals to the PR-1000’s actuator.
The microprocessor also updates the encoder’s rotary position and
sends the information back to the host application.
Upon receiving this position or selection information, the application
updates the user interface, determines the need for control action, and
updates the encoder’s profile, if applicable.
