mTouch™ DIAGNOSTIC TOOL OVERVIEW
FIGURE 1-3:
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
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.
The mTouch™ Diagnostic Tool is a Windows
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
Trip threshold and acceptable hysteresis signaling a sensor touch can easily be
determined by visualizing sensor behavior.
