Twenty four (24) Channel Rotary Encoder

MCDU Testing
The MCDU display and electronics connect to a standard 15-pin VGA connector. (No TV-out hack for this
system) The keypad is encoded with a
keyboard chip and decoded in software. A better solution is to use a custom Hagstrom encoder chip for
detecting keypad entries.
AeroEnvironment Support The basic set of boards provide 24 channels for rotary encoders, 8 A/D channels with 12-bit accuracy, and 128 positions for momentary, static, and rotary switches. Interface is provided via USB ports to a Linux based SBC. All boards contain logic and memory to retain data and event actions and set data ready flags for reading by applications programs via simple polling techniques. These boards can also be configured to operate with an interrupt-based protocol. Additional boards can be added in any combi nation as needed.LFS software libraries and drivers provide plug and play support and clean and direct access to USB ports for reading data thereby facilitating development of application software. Low level output of raw binary data and switch action allows for a wide range of options for customization by the end users and flexibility in programming. In addition, the libraries and drivers can be modified by LFS to meet unique customer requirements. |
