User Manual

On the host, the Arduino appears as a virtual RS-232 serial device. Data is sent to/from the Arduino

using a serial API, such as the one available in .NET.

The Arduino calculates a timestamp for each packet using the Arduino’s crystal controlled oscillator.

This can be used as the time for each sensor.

The serial commands, which mirror the raw I

C commands (as shown in blue in Figure 16), are

outlined in the following tables. Header and footer bytes are added to easily delimit serial packets. A

timeout can be specified for I

C transfers.
