Analog Inputs/Outputs
1-3
Introduction
Power supplies are derived from the USB bus, or may be provided to the kit
through external connectors from an external user-supplied laboratory power
supply.
1.3 Analog Inputs/Outputs
Touch screen inputs are provided to the controller through J3. This connector
is standard on 3M Touch Systems (formerly MicroTouch) TouchTek 4 touch
screens. Alternate touch screen input connections are provided on the J1
terminal block. The other analog inputs are brought onto the board through the
J4 terminal block. The AUX inputs must be between 0 V and 3.3 V, whereas
the battery input VBAT can range from 0 V to 6 V.
On the audio side, there are various audio input/output connectors or plugs
that allow the onboard microphone (MK1) or external microphone (J6) signal,
and a cell phone input signal or a BUZZ input (J2), into the device. The J8
output terminal provides a connector to a 32-Ω speaker; and the J9 output
terminal provides a connector to an 8-Ω speaker. Also, a headset can be
directly connected into the EVM board through the J7 audio plug.
1.4 External Voltage Reference
If the external voltage reference is used, the reference can be input to the
TSC2101 device through the J5 terminal block.
1.5 Power Requirements
The TSC2101EVM can be powered from either the USB port or an external
6-Vdc to 10-Vdc power supply.
1.6 Computer Requirements
The TSC2101EVM software is designed for a Windows based platform PC
that supports USB (Windows 98SE, 2000, XP, etc).
Minimum requirements include:
- IBM-compatible Pentium PC or higher
- Windows 98SE/2000/XP
- 64-MByte RAM minimum
- 20-MByte available hard disk space
- CD-ROM drive
- USB port
