Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : I2C type

Software Support

We provide a library for the ISOADC3 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 ISOADC3 Click driver.

Standard key functions :

  • isoadc3_cfg_setup Config Object Initialization function.

    void isoadc3_cfg_setup ( isoadc3_cfg_t *cfg );
  • isoadc3_init Initialization function.

    err_t isoadc3_init ( isoadc3_t *ctx, isoadc3_cfg_t *cfg );

Example key functions :

  • isoadc3_read_adc Read ADC function.

    uint16_t isoadc3_read_adc ( isoadc3_t *ctx );
  • isoadc3_get_adc_voltage Read ADC voltage function.

    uint16_t isoadc3_get_adc_voltage ( isoadc3_t *ctx, uint16_t v_ref );
  • isoadc3_read_voltage Read voltage function.

    uint16_t isoadc3_read_voltage ( isoadc3_t *ctx, uint16_t v_ref );

Example Description

This example shows the capabilities of the ISO ADC 3 Click.

The demo application is composed of two sections :

Application Init

Initalizes I2C driver and makes an initial log.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    isoadc3_cfg_t isoadc3_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.
    isoadc3_cfg_setup( &isoadc3_cfg );
    ISOADC3_MAP_MIKROBUS( isoadc3_cfg, MIKROBUS_1 );
    err_t init_flag = isoadc3_init( &isoadc3, &isoadc3_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

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

Application Task

Measures ADC voltage level and prints it via USB UART terminal.


void application_task ( void ) {
    voltage = isoadc3_read_voltage( &isoadc3, ISOADC3_VREF_3V3 );
    log_printf( &logger, " ADC voltage Level: %d mV \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.ISOADC3

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.

Ambient 16 Click

0

Ambient 16 Click is a compact add-on board used to measure the amount of the present ambient light. This board features the BH1726NUC, a 16-bit digital-output ambient light sensor with an I2C interface from Rohm Semiconductor. The BH1726NUC can detect a wide range of illuminance up to 30klx and provides excellent responsivity close to the human eyes' response. It is designed to control the brightness in various applications based on ambient light availability, brightness for optimum visibility, and energy efficiency.
