Features

QE for Capacitive Touch is an assistance tool for applications which operate under the e² studio integrated development environment.

For the development of embedded systems that are work with capacitive touch sensors, this tool simplifies the initial settings of the touch user interface and the tuning of the sensitivity, thus shortening developing times.

Functions

The GUI makes it easy for even a beginner to develop touch user interfaces.

Simple GUI operations allow even a beginner to create the configuration for use with a touch user interface, monitor the state of input through the touch sensors, and adjust parameters.

Furthermore, since this tool can adjust tuning parameters and reflect the results through display in real-time, it is very useful for finding the appropriate parameters in various situations, such as in the presence of much static electricity or in cases of use with wet hands.

Automatic tuning for touch sensor sensitivity

This tool enables automatic tuning for the sensitivity of the capacitive touch sensors. You can complete basic tuning within a few minutes by following the instructions in the pop-up messages.

Adding and Setting Middleware Related to QE for Capacitive Touch

RA Family: Capacitive touch sensor Pins and Stacks Configuration can be easily performed in conjunction with the Configurator

The following FSP components for RA family are supported.

  • CTSU (Capacitive Touch Sensing Unit) Driver "r_ctsu"
  • Touch Driver "rm_touch"

Add the FSP components related to the Capacitive Touch Sensor and generate project content for the RA family MCU that has the Capacitive Touch Sensor function. Then, run the pins configuration function. In this mode, you can easily set up stack configuration (such as pin assignment for use with capacitive touch sensor pins or Hardware Abstraction Layer (HAL)).

See here for details of Flexible Software Package (FSP) >>

RX Family: Interlinking with the Smart Configurator eases setting up the pins for use with capacitive touch sensors.

When generating a project to which the FIT module related to capacitive touch sensors is to be added, select the checkbox of "Smart Configurator" to run the Smart Configurator. This makes it easy to configure the settings of pin allocation for use with a capacitive touch sensor from the e² studio.
