``lu9685,servo,<pin>,<angle>``

``[<taskname>].lu9685,servo,<pin>,<angle>``
|
|
|
|
pin: 0 ... 19 or ``all``

angle: 0 ... 180 (``-1`` will disable the output on the given pin)

**Set specified pin to output a pulse duration for a servo**
|
|
|
|
The pulse width from 0.5 msec ... 2.5 msec is interpreted by a servo as an angle from 0 ... 180 degree.
|
|
Some servos have a range of 270 degree. However the input value for this command is still from 0 ... 180.
|
|
|
|
When ``all`` is used as pin, these commands refer to all pins on the addressed LU9685.
|
|
|
|
Examples:
|
|
|
|
* ``lu9685,servo,all,123``
|
|
* ``lu9685,servo,1,123``

**Enable or disable pulse output on specified pin(s)**
|
|
|
|
``enable`` will restore the last set 'angle' to be output on the specified pin(s).
|
|
|
|
``disable`` will stop outputting the servo pulse on the specified pin(s).

``[<taskname>].lu9685,setrange,<startpin>,<startVarIndex>,<nrPins>``
|
|
|
|
startpin: 0 ... 19 or ``all``
|
|
|
|
startVarIndex: first index of a variable referring to 'N' similar to ``[int#N]``

nrPins: 1 ... 19

|
|
**Set a range of pins to output a value as defined in variables.**
|
|
|
|
This command will copy the set values of a sequence of variables to a set range of pins.
|
|
|
|
If a referred variable was never set, the matching pin will be disabled.
|
|
|
|
This command will set all pins in a single I2C call, which limits communication overhead and also results in all pins being set at the same time.
|
|
|
|
.. note:: This will only update the pins when calling this command. It is not a continuous synchronisation between variables and pins.
|
|
|
|
For example:
|
|
``lu9685,setrange,10,1000,2`` Will use the values stored in ``[int#1000]`` and ``[int#1001]`` to set pins ``10`` and ``11``.
