ADC 6 Click

ADC 6 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.

Example Description

This example collects data from the sensor, calculates the voltage to a digital value and then logs it.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ADC6

Example Key Functions

• adc6_cfg_setup Config Object Initialization function.

void adc6_cfg_setup ( adc6_cfg_t *cfg );

• adc6_init Initialization function.

err_t adc6_init ( adc6_t *ctx, adc6_cfg_t *cfg );

• adc6_default_cfg Click Default Configuration function.

void adc6_default_cfg ( adc6_t* ctx );

• adc6_get_adc_data Get data function

uint32_t adc6_get_adc_data ( adc6_t* ctx );

• adc6_read_reg Generic read function

uint32_t adc6_read_reg ( adc6_t* ctx, uint8_t register_address );

• adc6_write_reg Generic write function

void adc6_write_reg ( adc6_t* ctx, uint8_t register_address, uint32_t transfer_data );

Application Init

Initializes driver and sets configuration which enables channel 0, puts AIN0 on positive analog input and AIN1 on negative analog input, enables internal reference voltage (approximately 2.65V (AVDD = 3.3V)), and also enables bipolar operation mode and puts device on full power mode. When the ADC is configured for unipolar operation, the output code is natural (straight) binary with a zero differential input voltage resulting in a code of 0x00000000, a midscale voltage resulting in a code of 0x00800000, and a full-scale input voltage resulting in a code of 0x00FFFFFF. When the ADC is configured for bipolar operation, the output code is offset binary with a negative full-scale voltage resulting in a code of 0x00000000, a zero differential input voltage resulting in a code of 0x00800000, and a positive full-scale input voltage resulting in a code of 0x00FFFFFF.

void application_init ( void )
{
    log_cfg_t log_cfg;
    adc6_cfg_t cfg;

    /** 
     * 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.

    adc6_cfg_setup( &cfg );
    ADC6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    adc6_init( &adc6, &cfg );
    adc6_default_cfg( &adc6 );

}

Application Task

Gets 24-bit converted data in single read mode and logs data on USB UART. Repeats operation every 500 ms.

void application_task ( void )
{
    uint32_t adc_value = 0;

    adc_value = adc6_get_adc_data( &adc6 );

    log_printf( &logger, "The ADC value is: 0x%.6LX\r\n", adc_value );

    Delay_ms ( 500 );
}

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.
