This is an example which demonstrates the use of StereoAmp Click board - stereo amplifier and is ideal for battery operated devices or as a lab amplifier.
We provide a library for the StereoAmp Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for StereoAmp Click driver.
Config Object Initialization function.
void stereoamp_cfg_setup ( stereoamp_cfg_t *cfg );
Initialization function.
STEREOAMP_RETVAL stereoamp_init ( stereoamp_t ctx, stereoamp_cfg_t cfg );
Click Default Configuration function.
void stereoamp_default_cfg ( stereoamp_t *ctx );
This function set the power On of both channels by write to the Mode Control register address of LM48100Q-Q1 chip on StereoAmp Click board.
void stereoamp_set_power_on ( stereoamp_t *ctx );
This function set the volume of both channels to the Volume Control register address of LM48100Q-Q1 chip on StereoAmp Click board.
void stereoamp_set_volume ( stereoamp_t *ctx, uint8_t volume );
This example shows how to initialize amplifiers and set volume control registers on the fly.
The demo application is composed of two sections :
Application Init perfroms Logger and Click initialization.
void application_init ( void )
{
log_cfg_t log_cfg;
stereoamp_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

This examples first set volume level 20 of 31 ( gain: 1,5 dB ) for 10 seconds. After that, we increase the volume to level 10 ( gain: -13,5 dB ) for the next 10 seconds. Results are being sent to the UART Terminal where you can track their changes.

Additional notes and infromations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
