Detailed Description

I2S pin assignment for a board's audio codec/amplifier. Not used by TinyGPU itself - hand these to the audio library of choice (e.g. audio_tools::I2SConfig's pin_mck/pin_bck/pin_ws/pin_data/pin_data_rx). -1 means "not present on this board".

paEnable/paEnableActiveLow describe a separate GPIO some boards use to gate the speaker amplifier (not part of the I2S bus itself, but bundled here since it's only ever needed alongside these pins).

Member Function Documentation

◆ isValid()

bool isValid ( ) const

inline

True if this board has a usable I2S bus (bck/ws plus at least one of dataOut/dataIn) wired up.
