Maybe some of you here have been involved with the touchscreen, but how far do you think that you’re familiar with it? By the way, would you mind to spend a few minutes and develop this Smart E-Touch?

The main objective of this project is to design an E-Field that based on a Motorola microcontroller. For your information, this project is based on a Motorola Nitron QY4 microcontroller. Honestly, this is an intelligent, low cost and dual E-Field sensed touchscreen design.

By using the Smart E-Touch, you’re able to:

• Utilize the capabilities of the new Motorola E-field sensor.
• Implement a simple user interface design using the Motorola Nitron QY4 microcontroller.
• Design the user interface with lower cost.
• Insert a unique breakthrough concept in user interface design.

The main reason why the Motorola Nitron QY4 microcontroller is being used in this project is to monitor and control a pair of MC33794 E-field sensors.

In other hand, the E-field sensors will be used to monitor an XY grid on a PCB for the capacitive sensing of the touchscreen. An XY coordinate is outputted, only after the Nitron QY4 microcontroller has translated a “touch” from the E-field sensor data!

As a main part of the Smart E-Touch, the touchscreen is built right at the center of the actual circuit board.
