4.2.8 Digital output humidity sensors: supported commands
Table 11. Digital output pressure sensors: supported commands list below lists the commands supported by the
devices/demonstration boards including a digital output humidity sensor.
Table 12. Digital output humidity sensors: supported commands list
Command Description Returned value
*setdbXXXVY Selects firmware according to the adapter connected
*start Starts continuous data acquisition (see Table 4. Returned values for *start command)
*debug Returns the output data in readable text format (see Table 5. Returned values for *debug command)
*stop Stops data acquisition
*Zon Forces 3-state
*Zoff Exits from 3-state
*dev Device name e.g.: LIS3DH
*ver Firmware version e.g.: V1.0
*hrAA Humidity sensor register read e.g.: HRAAhDDh
*hwAADD Humidity sensor register write
*single It gets a single X, Y, and Z data acquisition (see Table 5. Returned values for *debug command)
*list Prints the list of MKIs supported e.g.: MKI105V1
*listdev Prints the list of devices supported e.g.: LIS3DH
*echoon Activates the write verbose mode e.g.: PRAAhDDh
*echooff Deactivates the write verbose mode
4.3 Quick start
This section shows the basic sequence of commands, based on the LIS3DH accelerometer, to start a data
communication session and to retrieve the X, Y, and Z acceleration data from the demonstration kit:
1. Connect the eMotion to the USB port
2. Start “Microsoft
©
HyperTerminal” and configure it as described in Section 4.1 Getting started
3. Inside the “HyperTerminal” window, enter the command *setdb105v1 (supposing the LIS3DH adapter board
is used, for other adapters see the relevant datasheets to check the register configuration), enter the
command *Zoff to enable the control of the device by the STM32F103RET6 microcontroller, and *w2047 to
switch on the LIS3DH and to set the data rate to 50 Hz
4. Send the *debug command to get the X, Y, and Z data measured by the sensor
5. Send *stop to end the continuous acquisition and visualization.
