AD535 API Module Description
2-2
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().
