Supported commands

39

Stop command

The *stop command interrupts any acquisition session that has been started with either the 
*start or *debug commands.

Zon and Zoff

The *Zon and *Zoff commands are employed, respectively, to put into 3-state the 
STM32F103RET6 microcontroller mounted on the demonstration kit. These commands 
allow the isolation of the sensor from the microprocessor and let the user interact with the 
sensor in a pure analog way.

By default, when the kit is first turned on, the lines are in 3-state mode and the user is 
required to send the *Zoff command to allow communication between the sensor and the 
microcontroller. If Zoff has not been launched, the firmware ignores any other command.

Device name

The *dev command retrieves the name of the adapter connected to the demonstration kit. 
The returned value is, for example, 

“

LIS3DH

”

.

Firmware version

The *ver command queries the demonstration kit and returns the version of the firmware 
loaded in the microprocessor, for example, “V1.0”.

Accelerometer register read

The *rAA command allows the contents of the accelerometer registers in the demonstration 
kit board to be read. AA, expressed as a hexadecimal value and written in upper case, 
represents the address of the register to be read.

Once the read command is issued, the board returns RAAhDDh, where AA is the address 
sent by the user and DD is the data present in the register.

For example, to read the register at address 0x20, the user issues the command *r20, which 
returns, e.g., R20hC7h.

Accelerometer register write

The *wAADD command allows writing to the contents of the accelerometer registers in the 
demonstration kit board. AA and DD, expressed as hexadecimal values and written in upper 
case, represent, respectively, the address of the register and the data to be written. For 
example, to write 0xC7 to the register at address 0x20, the user issues the command 
*w20C7.
