Functions
thumby.audio.play(freq, duration) | plays audio at sound frequency freq for duration in milliseconds without blocking code execution. For now, try searching 'music notes to frequency chart' to relate these parameters to musical notes. freq can technically range from 7Hz-125MHz, but human hearing is in the 20-20000Hz range. Returns None
freq- type: int
- values: 20 ~ 20000 (Hz)
duration- type: int
- values: 0 ~ 2147483647 (ms)
thumby.audio.playBlocking(freq, duration) | plays audio at sound frequency freq for duration in milliseconds while blocking code execution. For now, try searching 'music notes to frequency chart' to relate these parameters to musical notes. freq can technically range from 7Hz-125MHz, but human hearing is in the 20-20000Hz range. Returns None
freq- type: int
- values: 20 ~ 20000 (Hz)
duration- type: int
- values: 0 ~ 2147483647 (ms)
thumby.audio.stop() | stops playing any running audio started by thumby.audio.play(...). Returns None
thumby.audio.set_enabled(setting) | stops buzzer from outputting sound when thumby.audio.play() or thumby.audio.playBlocking() are called using setting flag. thumby.audio.playBlocking(...) will still block subsequent code execution for the duration provided to it. Returns None
setting- type: bool
- values: 1/True (audio enabled) or 0/False (audio disabled)
Advanced Community-fueled Usage
It's possible to make more complicated sound effects and music with Thumby using software. Check out the arcade game Melody Maker made by SuperRiley64 (@FestyWalrus on GitHub) to make your own tunes that save to Thumby, or use an audio library to take your Thumby music to the next level.
Background: Thumby Rev 6 utilizes a piezo disc connected through a buffer to a GPIO pin to create audio effects. Anything other than a square wave on one channel requires more software.
An impressive community developed audio library, Thumby Polysynth, made by @transistortester allows for more complicated audio configurations, please take a look at their README on their GitHub Repository for more information.
