  • Page 14: Supported Commands

    UM1579 Supported commands Supported commands The microcontroller mounted on the BlueMotion board is equipped with dedicated firmware that supports a set of commands which allows either the digital or the analog output MEMS sensor to be controlled and permits the acquisition of the measured data. The firmware also handles the communication between the board and the PC through a Bluetooth connection.

  • Page 16 Start command The *start command initiates the continuous data acquisition. When this command is sent to the device, it returns a string of bytes (plus carriage return and line feed) similar to “st OUT1 OUT2 OUT3 IR BT”. The first two bytes are always the ASCII char “s” and “t” which correspond to the hexadecimal values {73h 74h}.
  • Page 17 Supported commands UM1579 Debug command The *debug command starts the continuous data acquisition in debug mode. When this command is sent to the board, it returns the output values measured by the device formatted in a readable text format. The values shown on the screen correspond to the LSB data shown as a decimal number.
  • Page 18 UM1579 Supported commands Accelerometer register read The *rAA command allows the contents of the accelerometer registers in the demonstration 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.
  • Page 19 Supported commands UM1579 Single acquisition The *single command may be used to read just one set of data. It requires the sensor to be well configured and once invoked, returns the read values of one data sample. 4), in The format of the returned value is exactly the same as the *debug command (Table fact, the *debug command is used for continuous data acquisition purposes whereas a *single command returns just one set of data.
