ISO ADC 5 Click

ISO ADC 5 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Type : SPI type

Software Support

Example Description

This example demonstrates the use of ISO ADC 5 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ISOADC5

Example Key Functions

• isoadc5_cfg_setup Config Object Initialization function.

void isoadc5_cfg_setup ( isoadc5_cfg_t *cfg );

• isoadc5_init Initialization function.

err_t isoadc5_init ( isoadc5_t *ctx, isoadc5_cfg_t *cfg );

• isoadc5_write_register This function writes two bytes of data to the selected register by using the SPI serial interface.

err_t isoadc5_write_register ( isoadc5_t *ctx, uint8_t reg, uint16_t data_in );

• isoadc5_read_register This function reads two bytes of data from the selected register by using the SPI serial interface.

err_t isoadc5_read_register ( isoadc5_t *ctx, uint8_t reg, uint16_t *data_out );

• isoadc5_read_voltage This function reads the raw adc data from a desired input channel and converts it to voltage.

err_t isoadc5_read_voltage( isoadc5_t *ctx, uint8_t filt, uint8_t ch, float *volt );

Application Init

Initializes the driver and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;          /**< Logger config object. */
    isoadc5_cfg_t isoadc5_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 );
    Delay_ms ( 100 );
    log_info( &logger, " Application Init " );

    // Click initialization.
    isoadc5_cfg_setup( &isoadc5_cfg );
    ISOADC5_MAP_MIKROBUS( isoadc5_cfg, MIKROBUS_1 );
    err_t init_flag  = isoadc5_init( &isoadc5, &isoadc5_cfg );
    if ( SPI_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

Reads the voltage from all input channels and displays the values of each channel on the USB UART approximately every second.

void application_task ( void )
{
    float v_ain1 = 0, v_ain2 = 0, v_ain3 = 0, v_ain4 = 0;
    err_t error_flag = isoadc5_read_voltage( &isoadc5, ISOADC5_ADC_FILTERED, ISOADC5_ADC_CHANNEL_1, &v_ain1 );
    error_flag |= isoadc5_read_voltage( &isoadc5, ISOADC5_ADC_FILTERED, ISOADC5_ADC_CHANNEL_2, &v_ain2 );
    error_flag |= isoadc5_read_voltage( &isoadc5, ISOADC5_ADC_FILTERED, ISOADC5_ADC_CHANNEL_3, &v_ain3 );
    error_flag |= isoadc5_read_voltage( &isoadc5, ISOADC5_ADC_FILTERED, ISOADC5_ADC_CHANNEL_4, &v_ain4 );
    
    if ( ISOADC5_OK == error_flag )
    {
        log_printf( &logger, " AIN 1 voltage: %.3f V\r\n", v_ain1 );
        log_printf( &logger, " AIN 2 voltage: %.3f V\r\n", v_ain2 );
        log_printf( &logger, " AIN 3 voltage: %.3f V\r\n", v_ain3 );
        log_printf( &logger, " AIN 4 voltage: %.3f V\r\n\r\n", v_ain4 );
        Delay_ms ( 1000 );
    }
}

Note

The voltage input range is from 0 to 48V.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
