Now a 'once' and a 'loop' buffer can be specified. 'once' is useful for things like writing a neopixel strip in the background, if you can guarantee the buffer contents are stable until the write is complete. 'loop' is useful for periodic things, like pwm & servos. both together are useful for some special cases of pwm/servo, where a transitional waveform needs to be played for one repetition and then a new waveform needs to be played after that. The API is renamed to reflect that it's a more generic 'background' operation. |
