Click library

  • Author : Nenad Filipovic
  • Date : Dec 2020.
  • Type : UART type

Software Support

We provide a library for the Adc10 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 10 Click driver.

Standard key functions :

  • adc10_cfg_setup Config Object Initialization function.

    void adc10_cfg_setup ( adc10_cfg_t *cfg );
  • adc10_init Initialization function.

    err_t adc10_init ( adc10_t *ctx, adc10_cfg_t *cfg );
  • adc10_default_cfg Click Default Configuration function.

    void adc10_default_cfg ( adc10_t *ctx );

Example key functions :

  • adc10_start_sync ADC 10 Start the synchronization function.

    void adc10_start_sync ( adc10_t *ctx );
  • adc10_get_ch_output ADC 10 Get the channel output function.

    int32_t adc10_get_ch_output ( adc10_t *ctx, uint8_t sel_ch );
  • adc10_calc_voltage ADC 10 Calculate the voltage function.

    float adc10_calc_voltage ( adc10_t *ctx, int32_t adc_data, float vref, uint8_t gain );

Examples Description

This is an example that demonstrates the use of the ADC 10 click board.

The demo application is composed of two sections :

Application Init

Initialization driver enables - UART, select analog input channel 0, perform a hardware and software reset and set the default device configuration, also, write a log.


void application_init ( void ) {
    log_cfg_t log_cfg;      /**< Logger config object. */
    adc10_cfg_t adc10_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_printf( &logger, "\r\n-------------------------\r\n" );
    log_info( &logger, " Application Init " );

    // Click initialization.

    adc10_cfg_setup( &adc10_cfg );
    ADC10_MAP_MIKROBUS( adc10_cfg, MIKROBUS_1 );
    err_t init_flag  = adc10_init( &adc10, &adc10_cfg );
    if ( init_flag == UART_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    select_ch = ADC10_ANALOG_INPUT_CH_3;

    // Hardware reset.

    adc10_hw_reset( &adc10 );
    Delay_ms( 100 );

    // Software reset.

    adc10_reset( &adc10 );
    Delay_ms( 1000 );

    // Click default configuration.

    adc10_default_cfg ( &adc10 );
    log_info( &logger, " Application Task " );
    Delay_ms( 100 );
}

Application Task

In this example, we monitor and display 24-bits of data ( from 0 to 8388607 ) of ADC and voltage ( from 0 mV to 2048 mV ) on the selected channel ( CH-0, CH-1, CH-2 or CH-3 ). Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes approximately for every 1 sec.


void application_task ( void ) {   
    adc10_start_sync( &adc10 );
    Delay_ms( 1 );

    while ( adc10_check_drdy( &adc10 ) == ADC10_NEW_DATA_NOT_READY );

    out_data = adc10_get_ch_output( &adc10, select_ch );
    log_printf( &logger, "-------------------------\r\n" );
    log_printf( &logger, "  ADC CH-%u : %.0f\r\n", ( uint16_t ) select_ch, ( float ) out_data );

    voltage = adc10_calc_voltage( &adc10, out_data, ADC10_VREF_INTERNAL, ADC10_GAIN_1 );
    log_printf( &logger, "  Voltage  : %.2f mV\r\n", 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.Adc10

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.
