Click library

  • Author : Jelena Milosavljevic
  • Date : Jun 2021.
  • Type : ADC type

Software Support

We provide a library for the CO 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 CO Click driver.

Standard key functions :

  • co_cfg_setup Config Object Initialization function.

    void co_cfg_setup ( co_cfg_t *cfg );
  • co_init Initialization function.

    CO_RETVAL co_init ( co_t *ctx, co_cfg_t *cfg );

Example key functions :

  • co_read_an_pin_value This function reads results of AD conversion of the AN pin.

    err_t co_read_an_pin_value ( co_t *ctx, uint16_t *data_out );
  • co_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

    err_t co_read_an_pin_voltage ( co_t *ctx, float *data_out );

Example Description

The demo application shows the reading of the adc values given by the sensors.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    co_cfg_t co_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.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.

    co_cfg_setup( &co_cfg );
    CO_MAP_MIKROBUS( co_cfg, MIKROBUS_1 );
    if ( co_init( &co, &co_cfg ) == ADC_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Reads the adc value and prints in two forms (DEC and HEX).


void application_task ( void ) {
    uint16_t co_an_value = 0;

    if ( co_read_an_pin_value ( &co, &co_an_value ) != ADC_ERROR ) {
        log_printf( &logger, " ADC Value : %u\r\n", co_an_value );
    }

    float co_an_voltage = 0;

    if ( co_read_an_pin_voltage ( &co, &co_an_voltage ) != ADC_ERROR ) {
        log_printf( &logger, " AN Voltage : %.3f[V]\r\n\n", co_an_voltage );
    }

    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.CO

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.

SPI Isolator 5 Click

0

SPI Isolator 5 Click is a compact add-on board with a digital isolator optimized for a serial peripheral interface. This board features the DCL541A01, a high-speed quad-channel digital isolator from Toshiba Semiconductor. Outstanding performance characteristics of the DCL541A01 are achieved by Toshiba CMOS technology and the magnetic coupling structure. In addition, they comply with UL 1577 safety-related certification, have a withstand voltage rating of 5kVrms, and operate with the external supply voltage ranging from 2.25V to 5.5V, providing compatibility with lower voltage systems enabling voltage translation functionality across the isolation barrier.
