Firmware-820 Function-109
VOLTD (109, 6Dh)
The VOLTD function enables output of the VoltD 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. The following methods can be selected using the FUNCTION command’s method/parameter FP:

The method can set the gain, where the VoltD input voltage range is halved each time the gain is doubled.
Example:
In order to enable the VOLTD function to get the 12-bit voltage data in the 0..5.12 Volt range (ie. gain = 1) from a VoltD sensor with I2C device address 104 (default VoltD I2C device address) connected to the 7th I2C port, the following message is sent:
- 240, 125, 0 {DEV}, 8 {FUNCTION}, 6 {port}, 104 {device address}, 109 {VOLTD function}, 0 {12-bit voltage, gain = 1}, 247 (F0h, 7Dh, 00h, 08h, 06h, 68h, 6Dh, 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.
