1.1
STw5095 within a system
Control Interface
The STw5095 has a versatile control interface permitting both accesses in I2C mode and in SPI mode. Thus, the system designer can choose between these 2 interfaces.
1.2
About the driver package
The delivered drivers and functions are located on the next upper layer compared to the level where the interface drivers such as I2C or SPI are located. This means that the drivers/functions described in this manual call lower level modules driving the data transfer on a given interface. STw5095 interface is based on an interface between its control registers and a user. The following functions and drivers are based on an I2C connection to the device. Functions related to this elementary data transfer need to be customized according to each application.
1.3
Groups of drivers
In this documents, drivers are split into 9 groups. These groups are related to the various entities of the device. These are: Power management, Analog inputs and analog mixing, Analog output, Analog to Digital and Digital to Analog conversion, DSP functions, Audio data interfaces, Interrupt control, Automatic gain control, Phase-Locked Loop (PLL) and clock control.
Chapter 3: Functions describes each group of functions in details.

Use of the drivers
These low level drivers permit to configure registers of the STw5095 audio codec by only calling functions with its corresponding parameters. They are written in C language. The software code, supplied with this documentation, has been tested on a target platform, and is usable in C and C++ environments. It can be applied to any hardware target.
Header files
Header files to include in your project in order to use the STw5095 low level drivers: #include "stw5095_low_level_drivers.h" #include "stw5095_register_values.h"
Functions to rewrite before using low level drivers:
These low level drivers are based on a control interface to communication with the audio codec. For the STw5095, the control interface can be I²C or SPI. The control interface is platform dependent; this is why it is necessary to rewrite the implementation of functions used for this purpose. The 2 functions to rewrite are the functions used to read and write the audio codec registers: stw5095_read_register stw5095_write_register
If you do not modify these functions, the low level drivers have no effect on the audio codec. You can see below functions prototypes, and an example of implementation.
"stw5095_read_register" prototype
char stw5095_read_register(char register_to_read); with returned value: data read parameter: "register_to_read" > Specify the register number where to read Example of implementation: char stw5095_read_register(char register_to_read) { char data_read; data_read = your_i2c_read_routine( STW5095_I2C_DEVICE_ADDR_READ, register_to_read); return data_read; }

Prototype char STw5095_ad_master_mode_freq( unsigned long sampling_frequency, unsigned long master_clock_freq) By only entering in parameter the sampling frequency and the master clock frequency, this function set the master clock frequency range (in register 30) and calculate and set the K coefficient (in register 23 24) for the desired sampling frequency (FS) in the clock generator. - unsigned long sampling_frequency: The sampling frequency (FS) in Hz - unsigned long master_clock_freq: The master clock frequency (AMCK) in Hz - return 0 if everything is OK. - return 1 if the K coefficient calculated is too big (greater than 0xFFFF), and the value 0xFFFF will be set. - return 2 if sampling frequency is too big. - return 3 if master clock frequency is too big. - return 4 if an error occurred when setting the master clock frequency range. STw5095_ad_master_mode_coeff( 44100, 320 0 00) This function is meaningful in Master Mode Only. By using this function, you don't have to use the following function: - set_master_clock_frequency_range( ) - set_ad_master_mode_coeff( ) 23 24 ; 30
