Public Member Functions | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| virtual AudioInfo | audioInfo () override |
| provides the actual input AudioInfo | |
| virtual AudioInfo | audioInfoOut () |
| provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream | |
| int | availableForWrite () override |
| bool | begin () |
| virtual bool | begin (AudioInfo info) |
| bool | begin (PWMConfig config) |
| starts the processing using Streams | |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| PWMConfig | config () |
| virtual PWMConfig | defaultConfig () |
| PWMDriver * | driver () |
| Provides access to the driver. | |
| virtual void | end () override |
| virtual void | flush () override |
| uint32_t | framesPerSecond () |
| virtual bool | isDeletable () |
| If true we need to release the related memory in the destructor. | |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| operator bool () | |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| virtual void | setAudioInfo (AudioInfo info) |
| updates the sample rate dynamically | |
| void | setBuffer (BaseBuffer< uint8_t > *buffer) |

Detailed Description
Common functionality for PWM output. Please use the PWMAudioOutput typedef instead which references the implementation.
