OVERVIEW
Chapter 1. Introduction to the Evaluation Board
Thank you for purchasing Microchip Technology’s mTouch™ Capacitive Evaluation Kit.
These evaluation boards are intended to introduce and demonstrate the possibilities for
capacitive touch sense applications on the PIC16F and PIC24F microcontroller
platforms.
This chapter introduces the evaluation kit and provides an overview of its features.
Topics covered include:
• Overview
• Operational Requirements
• Initial Board Setup
The mTouch Capacitive Evaluation Kit provides a simple platform for developing a
variety of capacitive touch sense applications. Two motherboards are included in the
kit, which connect to the 4 sensor boards, as shown in Figure 1-1 below.
This Capacitive Evaluation Kit is intended to be used to develop sensors and software
using Microchip’s mTouch technologies. It is used by first connecting a sensor board,
and then supplying power to the board via USB, Pickit™ 2, or Pickit Serial Analyzer.
The connector on the right side, with numbers 0 to 15, is the connector for sensing
channels. The number, from 0 to 15, represents the microcontroller’s sensing channel.
The vertical 2-row header is for debugging, to give easy access to some of the
microcontroller pins. Debugging may also be done by Microchip Programmers, or by
I
When using the evaluation kit out of the box, the LEDs default function is to illuminate
on a key press. All functionalities may be reprogrammed by using a Microchip
programmer, and reprogramming the firmware in the device. The firmware supplied
with the evaluation kit has been written to use the four sensor boards supplied.
The USB connection supplies power to the board; no additional external power supply
is needed. For independent operation, the evaluation board may be disconnected from
the PC and powered at test points for independent functionality. For the PIC24F board,
the USB also provides communications. The PIC16F board uses the PICkit Serial
Analyzer to communicate via I
the evaluation kit allows users to monitor the performance of the touch sensors and
calibrate their response. A separate, 6-wire programming interface allows users to
replace the preprogrammed demo firmware with their own applications using
Microchip’s MPLAB Integrated Development Environment and In-Circuit Serial
Programming™ (ICSP™). This allows the board to also be used as a test bed for
capacitive touch sense solutions.
