3.2 VOUT_ADC_Capture.ino - Standalone Example

For a demonstration that does not require any user-input, the Energia VOUT_ADC_Capture.ino runs to allow the TUSS44x0 settings to be initialized by hard-coded values, then continuously performs time-of-flight measurements to capture the VOUT output with an ADC input to report the echo envelope data points over a serial port. The serial port can be accessed by the Processing ADC_VOUT_Capture.pde sketch to visually depict the echo envelope over time per time-of-flight measurement.
