The PICDEM? Touch Sense 1 Development Board features three styles of touch
sensor pad configurations to optimize the design process:
? Directional pad
? Keypad
? Slider
The PICDEM? Touch Sense 1 Development Board comes populated with a 20-pin
PIC16F677 MCU and a 44-pin PIC16F887 MCU each with its own dedicated PICkit?
2 Programmer Connector (see Figure 1-3). Each PIC MCU comes factory programmed
with demonstration firmware and controls its own unique section of the PICDEM?
Touch Sense 1 Development Board. The PIC16F677 MCU is dedicated to the
Directional Pad while the PIC16F887 MCU to both the Keypad and Slider. I 2 C? serial
communication between both MCUs is made possible using on-chip Master
Synchronous Serial Port (MSSP) peripherals.
A PICkit? Serial Connector is included to enable communication with the PICDEM?
Touch Sense 1 Development Board using the mTouch Diagnostic Tool.

mTouch? DIAGNOSTIC TOOL OVERVIEW
The mTouch? Diagnostic Tool is a Windows ? based application that provides an intu-
itive means of analyzing a capacitive system. The mTouch Diagnostic Tool provides
communication with the PICDEM? Touch Sense 1 Development Board via the
PICKit? Serial Analyzer using the I 2 C protocol. Application critical information such as
Trip threshold and acceptable hysteresis signaling a sensor touch can easily be
determined by visualizing sensor behavior.
