发布信息

The ultrasonic design center is a one stop resource for everything related to ultrasonic sensing technology using MSP430™ microcontrollers (MCUs). It includes tools, graphical user interface (GUI), documentation, software library and application examples for developers to get started with project developments. The ultrasonic design center GUI is a rapid development tool for configuring and customizing various parameters related to transducers, pipe size as well as analyzing and capturing waveforms.
