Connecting to the virtual COM port
Before using the functions of the demonstration kit software, the connection with the
STEVAL-MKI0xxV1 board must be opened using the following steps:
1.
2.
3.
At this point, the user can acquire, plot and save the angular rate data measured by the
sensor and access the content of the registers embedded in the device.
If the “Find” button is pressed
COM number assigned to the demonstration kit, and displays it in the list box as a selected
item.
GUI main window functions
The following sections provide details regarding the functions of the tabs and buttons on the
GUI main window (see
“Easy Start” button
When the “Easy Start” button is clicked
find the COM number assigned to the demonstration kit, to recognize the connected board
and its device and, if successful, starts the acquisition. If recognition is unsuccessful, a
message alerts the user to verify that the board type is in the list of managed ones, or to
update the SW.

to which the board has been mapped. For additional information on how to obtain this
number, see section 3.3. Otherwise, press “Find” to automatically get the correct COM
number.
Open the connection by clicking on “Connect”
starts the board model recognition flow. If the flow terminates successfully, a
recognized board code and mounted device code is generated and written on the
“Home” tab. Otherwise, a message on the same tab alerts the user to check the board.
LSB: the analog values measured by the 8-bit A/D converter of the microcontroller
are converted to 8-bit values, hence the 256 magnitude levels.
Angular rate: LSB data are multiplied by the sensitivity to obtain the angular rate,
expressed in deg/sec.
