# Analog Set Period
|
|
|
|
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.
|
|
|
|
```sig
|
|
pins.analogSetPeriod(AnalogPin.P0, 20000)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* `pin`: a [string](/reference/types/string) that specifies the pin to configure (`P0` through `P4`, or `P10`)
|
|
* `μs`: 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.
|
|
|
|
```blocks
|
|
pins.analogWritePin(AnalogPin.P0, 512)
|
|
pins.analogSetPeriod(AnalogPin.P0, 20000)
|
|
```
|
