PDMCC26XX_I2S Object.
The application must not access any member variables of this structure!
| bool PDMCC26XX_I2S_Object::isOpen |
Has the object been opened
| uint8_t PDMCC26XX_I2S_Object::blockCount |
Number of PDM buffers the I2S driver can fill without the PDM driver processing them. Must be larger than 3.
| uint16_t PDMCC26XX_I2S_Object::blockSizeInBytes |
Size of an individual PDM block buffer in bytes
