Public Member Functions | |
int | available () |
we assume the data is already available in the buffer | |
int | availableForWrite () |
We limit the write size to the buffer size. | |
bool | begin () |
bool | begin (I2SConfigESP32V1 cfg) |
starts the DAC | |
bool | begin (RxTxMode mode) |
starts the DAC with the default config | |
I2SConfigESP32V1 | config () |
provides the actual configuration | |
I2SConfigESP32V1 | defaultConfig (RxTxMode mode) |
Provides the default configuration. | |
void | end () |
stops the I2C and unistalls the driver | |
size_t | readBytes (void *dest, size_t size_bytes) |
bool | setAudioInfo (AudioInfo info) |
Potentially updates the sample rate (if supported) | |
void | setWaitTimeReadMs (TickType_t ms) |
void | setWaitTimeWriteMs (TickType_t ms) |
size_t | writeBytes (const void *src, size_t size_bytes) |
writes the data to the I2S interface | |
