Set demonstration board
The command *setdbxxxvy selects the part of the firmware able to handle the adapter board sensor connected to
the board. e.g., in order to select the firmware for the LIS3DH the command must be: *setdb105V1. The D6 LED
(green) is automatically switched on.
Start command
The *start command initiates the continuous data acquisition. When this command is sent to the device, it returns
a string of bytes (plus carriage return and line feed) similar to "st OUT1 OUT2 OUT3 IR BT".
The first two bytes are always the ASCII char "s" and "t" which correspond to the hexadecimal values {73h 74h}.
OUT1, OUT2, and OUT3 are the bytes that contain the values measured at device outputs; if the output data is
represented on more than 8 bits, OUT1, OUT2, and OUT3 are split into two bytes: high byte (e.g.: "XH") and low
byte (e.g.: "XL").
IR contains the interrupt bytes and BT contains the bytes that describe the state of the buttons integrated on the
board.
