Firmware-73 Function-120
HOTSPOT2D (123, 7Bh)
The HotSpot2D function enables output of the MoveAlong 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:
HotSpot2D v1.0
| FP | Data output in host mode | Data output in stand-alone mode |
|---|---|---|
| 0..127 | Temperature [0..65536]; an unsigned 16-bit value, representing degrees Celsius, sent as two 8-bit bytes (MSB, LSB) | Temperature [0..127] or [0..16383]; an unsigned 7-bit or 14-bit value, where 0 represents 0 degrees Celsius and 127 or 16383 represents 100 degrees Celsius, sent as one or two 8-bit bytes (LSB, MSB) |
Example:
In order to enable the HotSpot2D function to get the angular velocity data from an HotSpot2D sensor with I2C device address 0 (default HotSpot2D I2C device address) connected to the 7th I2C port, the following message is sent:
- 240, 125, 0 {DEV}, 8 {FUNCTION}, 6 {yyy = 6}, 1 {device address}, 120 {HotSpot2D function}, 0 {}, 247 (F0h, 7Dh, 00h, 08h, 06h, 01h, 78h, 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 HotSpot2D sensor can be effectuated by using I2C commands such as I2C WRITE and I2C READ.
