|
|
|
Configure the period of Pulse Width Modulation (PWM) on the specified
|
|
|
|
|
analog [pin](/device/pins).
|
|
|
|
|
Before you call this function, you should set the specified pin as analog.

|
|
|
* ``name``: a [string](/reference/types/string) that specifies the pin to configure (`P0` through `P4`, or `P10`)
|
|
|
|
|
* ``micros``: a [number](/reference/types/number) that specifies the analog period in microseconds.

|
|
|
The following code first sets `P0` to analog with **analog write
|
|
|
|
|
pin**, and then sets the PWM period of `P0` to 20,000 microseconds.
