It can also be used in medical equipment, automotive control, building automation, and military hardware.

Working Principle

The CP7770BT uses a capacitive touch panel to sense user input. This panel is formed by a set of electrodes arranged in a two-dimensional set-up. When a user touches the panel, their finger acts as a conductive medium between the electrodes, resulting in a sudden change in the electrical characteristics of the panel. This change is detected by the device, and the location of the touch is calculated. This data is p rocessed and then sent to the MCU which is responsible for interpreting the user input and executing the corresponding commands.

Conclusion

The CP7770BT is a powerful and versatile touch screen controller that is ideal for industrial automation and other applications. It is highly configurable and offers a wide range of digital, analog, and communication interfaces. In addition, it has numerous features such as calibration, error logging, power control, and much more. Therefore, it is the perfect choice for any application that requires efficient data acquisition and touch screen control.
