Supported commands
The microcontroller mounted on the STEVAL-MKI0xxV1 board is equipped with dedicated
firmware which supports a set of commands that allow control of the single axis digital
output MEMS sensor and permit the acquisition of the measured angular rate data. The
firmware also handles the communication between the STEVAL-MKI0xxV1 and the PC
through the USB bus. These features allow users to easily write their own applications to
exploit the capabilities of the gyroscope.
This section describes the commands that are supported by the firmware for the
microcontroller of the STEVAL-MKI0xxV1 demonstration kit.
Getting started
Before using the commands supported by the firmware, the following procedure must be
performed:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Once this procedure has been completed the user can utilize the commands described in
the following sections by typing them into the Hyper Terminal window.
Supported commands
The table below lists the commands supported by the STEVAL-MKI0xxV1 firmware.
Some commands are valid only for DCWM. Using them outside of DCWM could result in
unexpected errors.
Supported commands
Connect the STEVAL-MKI0xxV1 to the USB port.
Launch an application that allows the sending of commands through the virtual serial
port. The remainder of this document assumes the use of Microsoft’s Hyper Terminal
program, available with the Windows XP operating system.
Create a new connection, enter a name (ex. “STEVAL-MKI0xxV1”), and click “OK”.
In the “Connect Using” field, select the virtual COM port to which the USB port has
been mapped, and click “OK”.
In port settings, set bits per second to 115200, data bits to 8, parity to none, stop bits to
1, and flow control to none. Click “OK”.
In the “Hyper Terminal” application window choose “files” > “properties” > “settings”,
then click on the “ASCII Setup” button.
Select “Send line ends with line feeds” and “Echo typed characters locally”.
Click the “OK” button to close the “ASCII Setup” window.
Click the “OK” button to close the “Properties” window.
Returns the angular rate data in readable text
