  • Author : Stefan Ilic
  • Date : Sep 2021.
  • Type : GPIO type

Software Support

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.

Library Description

This library contains API for MIC3 Click driver.

Example Description

This is an example that demonstrates the use of the MIC 3 Click board.

The demo application is composed of two sections :

Application Init

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;
mic3_cfg_t mic3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
mic3_cfg_setup( &mic3_cfg );
MIC3_MAP_MIKROBUS( mic3_cfg, MIKROBUS_1 );
if ( DIGITAL_OUT_UNSUPPORTED_PIN == mic3_init( &mic3, &mic3_cfg ) ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
mic3_default_cfg ( &mic3 );
log_info( &logger, " Application Task " );
}

Application Task

Turning microphone on for the 5 seconds, then turning it off for 5 seconds.

void application_task ( void )
{
log_printf( &logger, " - Microphone is turned on - \r\n" );
Delay_ms( 5000 );
log_printf( &logger, " - Microphone is turned off - \r\n" );
Delay_ms( 5000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.MIC3

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.
