Product Overview

The DM183026-2 is the enhanced mTouch Capacitive Touch evaluation kit provides a simple platform for developing a variety of capacitive touch sense applications using PIC16F, PIC18F, PIC24F and PIC32 microcontrollers along with four sensor daughter boards.The Diagnostic Tool provided allows the user to analyze application critical information in real-time as it relates to touch sensor behaviour. These evaluation boards are intended to be used to develop a capacitive touch sense application using mTouch Sensing Solution technologies. A board is used by first connecting a sensor daughter board, and then supplying power to the board via USB, a PICkit 3 In Circuit Programmer/Debugger, or the PICkit Serial Analyzer. The J3/J4 connector, with numbers from 0 to 15, is the connector for the sensor channels. The numbers, from 0 to 13 for PIC16F, from 0 to 12 for PIC18F, and from 0 to 15 for PIC24F, PIC24H, and PIC32, represent the sensor channels.
  • Capacitive touch sensing (mTouch) techniques are voltage based scanning methods
  • PIC16F/24H/32 microcontroller without a CTMU module use sample and hold capacitor to charge each key
  • The CTMU consists of a constant current source that provides a highly repeatable charge to each key
  • PIC16F/24H/32 microcontroller also use CTMU module to charge each button
  • The response of sensor to fingertip touch is influenced by many factor such as touch areas and so on
