Click library

  • Author : Nenad Filipovic
  • Date : Jul 2023.
  • Type : SPI type

Software Support

We provide a library for the ADC 22 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 ADC 22 Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of the ADC 22 Click board™ by reading and writing data by using SPI serial interface and reading results of AD conversion.

The demo application is composed of two sections :

Application Init

Initialization of SPI module and log UART. After driver initialization, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
adc22_cfg_t adc22_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
adc22_cfg_setup( &adc22_cfg );
ADC22_MAP_MIKROBUS( adc22_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == adc22_init( &adc22, &adc22_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
Delay_ms( 100 );
if ( ADC22_ERROR == adc22_default_cfg ( &adc22 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
Delay_ms( 100 );
log_info( &logger, " Application Task " );
log_printf( &logger, " ----------------\r\n" );
Delay_ms( 100 );
}

Application Task

The demo application reads the voltage levels from analog input and displays the results. By default, the operating input range sets from 0V to 12.288V [3×Vref;Vref=4.096V]. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
static float voltage = 0.0;
if ( ADC22_OK == adc22_get_voltage ( &adc22, &voltage ) )
{
log_printf( &logger, " Voltage : %.2f V\r\n", voltage );
log_printf( &logger, " ----------------\r\n" );
Delay_ms( 1000 );
}
}

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.ADC22

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.
