The MIC 3 Click is a Click board™ that features the SSM2167-1RMZ-R7, a Microphone Preamplifier, from Analog Device. This Click board™ is a low voltage Microphone preamplifier with Variable compression and noise gating.
We provide a library for the MIC3 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 NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for MIC3 Click driver.
mic3_cfg_setup
Config Object Initialization function.
void mic3_cfg_setup ( mic3_cfg_t *cfg );
mic3_init
Initialization function.
err_t mic3_init ( mic3_t *ctx, mic3_cfg_t *cfg );
mic3_default_cfg
Click Default Configuration function.
err_t mic3_default_cfg ( mic3_t *ctx );
mic3_shd_pin_set
MIC 3 SHD pin setting function.void mic3_shd_pin_set ( mic3_t *ctx, uint8_t state );
This is an example that demonstrates the use of the MIC 3 Click board.
The demo application is composed of two sections :
Initialization of SHD to output and log module, maping GPIO for Mikrobus1, and seting SHD pin to HIGH state.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
mic3_cfg_t mic3_cfg; /**< Click config object. */
/**
* 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.

Additional notes and informations
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. UART terminal is available in all MikroElektronika compilers.
