1 Overview
This document provides a description of the software and hardware used to demonstrate the features
of the Microchip CAP1xxx Family of RightTouchTM multiple-channel capacitive touch controllers and
LED drivers. Two evaluation boards are covered in this User's Manual. The CAP1188 evaluation board
contains the largest, full-featured version of the CAP11xx family. The other devices in this family are
the CAP1166, CAP1128, CAP1126, CAP1133, and CAP1106. Likewise, the CAP1298 evaluation board
contains the largest, full-featured version of the CAP12xx family. The other devices in this family are
the CAP1296, CAP1293, CAP1208, CAP1206, and CAP1203.
1.1 References
Readers should be familiar with or have access to the datasheet for the device and the schematic for
the evaluation board.
The datasheet is included with the CD provided with the evaluation board, and can also be
downloaded from the Microchip website at http://www.microchip.com/mtouch.
The schematic is included with the CD provided with the evaluation board.
1.2 The RightTouch Evaluation System
The evaluation system has three major parts, as shown in Figure 1.1:

1.2.1 Capacitive Sensing Device on the Evaluation Board
The CAP1188 device was chosen for the evaluation board because it has the most sensors and LEDs
in the CAP11xx family.
Note: The CAP1114 and CAP1214 devices, each with 14 sensors and 11 LED drivers, contain
additional features such as slider support which will be highlighted in their own evaluation
board.
The CAP1298 device was chosen for the evaluation board because it is the superset device in the
family, meaning it has the most sensors and features in the CAP12xx family including the signal guard.
The CAP1188, CAP1166, CAP1128, CAP1126, CAP1133, and CAP1106 are similar, with the exception
of the number of capacitive sensor inputs and LED drivers, as shown in Table 1.1.

2 Software and Hardware Installation
To begin using the CAP1xxx evaluation board, you only need to supply power by plugging in the USB
connector. However, in order to further evaluate the features of the CAP device, the CAP1xxx GUI
must be installed on a Windows-based computer with a USB port.
2.1 GUI Software Installation
Begin by inserting the CD provided with the evaluation board into the computer. Run the Setup.exe
program located in the root directory of the CD. This steps through the CAP1xxx GUI installation, which
takes less than a minute. Figure 2.1 shows the initial installation screen, which displays briefly as the
setup program loads.
