Start command (DWM only)
The *start command initiates the continuous data acquisition. When this command is sent to
the board, it returns the angular rate data measured by the device. The angular rate data are
packed in a string composed of 5 bytes (plus 2): “
bytes are always the ASCII char “s” and “t” which correspond to the hexadecimal values
{73h 74h}, while “R”, “4O2”, “O2”, “4O1” and “O1” respectively represent 8-bit AD converter
digital output data for Vref, 4xOutput2, 1xOutput2, 4xOutput1, 1xOutput1.
0h: one byte at hexadecimal value 0.
The last byte, marked “S”, returns information about the switches mounted on the board.
Specifically, bit#0 of the “service data” correspond to the status of SW2 on the
demonstration kit board. It is set to 1 when the SW2 switch is pressed (otherwise 0).
Before sending the *start command, the device must be out of 3-state and in DWM, hence
*start must have been preceded by a *Zoff command.
This is a digital working mode only command.
Debug command (DWM only)
The *debug command starts the continuous data acquisition in debug mode. When this
command is sent to the board, it returns the Vref value and all 4 outputs measured by the
device, digitized by the 8-bit AD converter and formatted to a readable text format. The
values shown on the screen correspond to the content of the ADC output data and are
shown as decimal numbers.
This is a digital working mode only command.
R: Vref value
4O2: 4xOutput2
4O1: 4xOutput1
0h: byte set to 0 hex value
s: service field
O2: 1xOutput2
O1: 1xOutput1
Exit from 3-state (enter in DWM)
Force 3-state (enter in AWM)
