TX
T1 system with a Faulhaber motor, Maxon amplifier, Grayhill keypad, and Parallax display.

Target computer
National Instruments (NI) myRIO 1900
The NI myRIO 1900 is a single-board computer. The board uses
field-programmable gate array (FPGA)-based fast input/output (I/O). The
operating system is the NI Linux Real-Time OS, which is based on the
popular Real-Time Linux OS.

User interface (UI) subsystem
User input device: Grayhill 88BB2
A 16-key keypad. The buttons are momentary contact single-pole
single-throw (SPST) switches. The circuitry is arranged in a \(4 \times 4\) matrix and requires 8 digital
input/output (DIO) lines to interface.

Display: Parallax 27979 LED dot-matrix display
An 80-character LCD transreflective dot-matrix display. It has four
20-character lines and each character has \(5
\times 8\) dots. The serial interface is natural for UART
communication. It requires a \(5\) V
supply.

Electromechanical subsystem
Amplifier: Maxon ESCON Module 24/2 466023
A small, digital, four-quadrant current amplifier with an analog input.
It can act as a controller, but we will use it as a current amplifier
(in “current controller” mode). It is compact, light, and relatively
inexpensive.

Prototyping and testing hardware subsystem
NAND integrated circuit (IC)
Generic—this part is generic and can be substituted with a similar part.
Name: TI SN7438N
Quantity: 1
Output-type: Open-collector
Logic-levels: TTL
Description: This is a chip with four NAND gates, \(5\) V supply (TTL), and open-collector
outputs. Get the PDIP package for breadboard prototyping. The 7401 will
also work, but we have chosen the 7438 because it is currently more
readily available. The 7438 can handle more current, but this is not
necessary for our application.
