3.1 GetDistance.ino - COM Terminal Input Example

Before the Energia sketch is run, a serial COM terminal should be opened to see the instructions and available command listing for the GetDistance.ino sketch. A two digit hex input with a newline terminator should always be entered for every request from the sketch. For example, to run a COM Ping Test, send "00" through the COM terminal. This sketch allows you to perform a single register read or write (commands 01 and 02), configure the time-of-flight driver and record settings of the MCU (command 03), run a time-of-fight command to print the time-of-flight results of the VOUT ADC capture and/or the O4 Echo Interrupt (command 04), and choose what results to capture and display (command 05).
