AD535 API Module Description

2.1 AD535 API Module Description

The AD535 module (audio codec supported by the C6711 DSK) serves as a level of abstraction such that it works the same for all AD535s supported on TI EVM/DSKs.

To use an AD535 device, you must first open it and obtain a device handle us- ing AD535_open(). Once opened, use the device handle to call the other API functions. The codec may be configured by passing an AD535_Config struc- ture to AD535_config().
