Example:
2.341
I2C Command Number: 44
Description
Returns Servo Offset voltage (in volts). When the servo is engaged, this voltage is the starting voltage that the servo integrates from. <html></div></html>
Arguments:
No Arguments Taken
Example:
I2C Command Number:
Description
Sets the Servo Offset voltage (in volts) to OUTPUT when the servo is turned off. When the servo is engaged, this voltage is the starting voltage that the servo integrates from. Returns the output of the command SvOffst?. <html></div></html>
