==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 as an I2C DATA message. 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. Since the MoveAround has multiple output parameters the stand-alone mode settings are incremented by one for each extra output parameter. There are no methods to select, ie. the FUNCTION command’s method/parameter FP is ignored:
MoveAround v1.0
| FP | Data output |
|---|---|
| 0..127: | Ambient Temperature; an unsigned 8-bit value sent as one 8-bit byte |
| Temperature (pixel 1); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 2); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 3); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 4); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 5); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 6); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 7); an unsigned 8-bit value sent as one 8-bit byte | |
| Temperature (pixel 8); an unsigned 8-bit value sent as one 8-bit byte |
Each 8-bit value represents the temperature value [4..100] in degrees Celsius.
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. The sensor parameter’s raw values as output in a I2C DATA message are offset and scaled so as to fit in the channel voice MIDI value range of either 0-127 (eg. control-change message) or 0-16383 (pitch-bend message).
Other settings of the MoveAround sensor can be effectuated by using I2C commands such as I2C WRITE and I2C READ.
