OVERVIEW
Chapter 1. Introduction to the Evaluation Boards
Thank you for purchasing a Microchip Technology mTouch Advanced Capacitive
Evaluation Kit. Depending on the kit purchased, up to four individual evaluation boards
are provided. These evaluation boards are intended to introduce and demonstrate the
possibilities for capacitive touch sense applications on the PIC16F, PIC18F, PIC24F,
(DM183026-2 kit), PIC24H (AC243026 kit) and PIC32MX microcontroller platforms.
This chapter introduces the evaluation kits and provides an overview of their features.
Topics covered include:
• Overview
• Operational Requirements
• Initial Board Setup
The mTouch Advanced Capacitive Evaluation Kits provide a simple platform for
developing a variety of capacitive touch sense applications. Depending on the kit
purchased, up to four evaluation boards are included with PIC16F, PIC18F, PIC24F,
PIC24H and PIC32MX microcontrollers, with four sensor daughter boards, as shown in
Figure 1-1 and Figure 1-2.
These evaluation kits are intended to be used to develop a capacitive touch sense
application using Microchip’s mTouch technologies. A kit is used by first connecting a
sensor board, and then supplying power to the board via USB, PICkit™ 3 or the PICkit
Serial Analyzer. The connector, J3/J4, with numbers from 0 to 15, is the connector for
sensing channels. The numbers, from 0 to 15 for PIC16F, PIC24F, PIC24H and
PIC32MX, and from 0 to 12 for PIC18F, 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 and
the I
When using an evaluation kit out of the box, the default function of the LEDs 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 is optimized to use with 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 the PIC18F, PIC24F and PIC32MX evaluation
boards, the USB also provides communications with the MPLAB mTouch Diagnostic
Tool. The PIC16F and PIC24H evaluation boards use the PICkit Serial Analyzer to
communicate via I
monitor the performance of the touch sensors and to optimize the sensor response. A
separate, 6-wire programming interface allows users to replace the preprogrammed
