Firmware-75 Function-124
MOVEAROUND (124, 7Ch)
The MoveAround function enables output of the MoveAround sensor data in both host and stand-alone mode. In host mode the sensor data is output in I2C DATA messages. In stand-alone mode the sensor data is output according to the stand-alone mode settings of the input number that equals the I2C port number. There are no methods to select, ie. the FUNCTION command’s method/parameter FP is ignored:

Each 8-bit value represents the temperature value [4..100] in degrees Celsius.
The centroid is the mean weighted value of all pixels.
Example:
In order to enable the MoveAround function to get the temperature data from a MoveAround sensor with I2C device address 104 (default MoveAround I2C device address) connected to the 7th I2C port, the following message is sent:
- 240, 125, 0 {DEV}, 8 {FUNCTION}, 6 {yyy = 6}, 104 {device address}, 124 {MoveAround function}, 0 {all temperatures}, 247 (F0h, 7Dh, 00h, 08h, 06h, 68h, 7Ch, 00h, F7h)
In host mode raw sensor data will be output immediately in I2C DATA messages. In stand-alone mode a suitable configuration has to be set using the EDIT CONFIG command before any MIDI messages will be output.
Other settings of the MoveAround sensor can be effectuated by using I2C commands such as I2C WRITE and I2C READ. See also the datasheet linked from the MoveAround v1.0 webpage.
