3D Hall 6 Click

3D Hall 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 application measure the intensity of the magnetic field across three perpendicular axes.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.3dHall6

Example Key Functions

• c3dhall6_cfg_setup Config Object Initialization function.

void c3dhall6_cfg_setup ( c3dhall6_cfg_t *cfg ); 

• c3dhall6_init Initialization function.

err_t c3dhall6_init ( c3dhall6_t *ctx, c3dhall6_cfg_t *cfg );

• c3dhall6_set_reference_values This function sets reference values for voltage and angle calculations.

void c3dhall6_set_reference_values ( c3dhall6_t *ctx, c3dhall6_aux_ref_t ref_val );

• c3dhall6_get_adc_value This function reads ADC value on selected channel.

void c3dhall6_get_adc_value ( c3dhall6_t *ctx, uint8_t channel_no, uint16_t *adc_value );

• c3dhall6_get_volt This function reads ADC value on selected channel and converts that value to Volts or miliVolts - depending on reference voltage setting.

void c3dhall6_get_volt( c3dhall6_t *ctx, uint8_t channel_no, float *channel_voltage );

Application Init

Initializes device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c3dhall6_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.
    c3dhall6_cfg_setup( &cfg );
    C3DHALL6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c3dhall6_init( &c3dhall6, &cfg );

    c3dhall6_aux_ref_t ref_val = 
    {
        .aux_ref_adc_ch0 = 2048.0,
        .aux_ref_adc_ch1 = 2048.0,
        .aux_ref_adc_ch2 = 2048.0,
        .aux_ref_adc_ch3 = 2048.0,
        .aux_ref_volt = 3.3
    };
    c3dhall6_set_reference_values( &c3dhall6, ref_val );
    
    log_info( &logger, " Application Task " );
}

Application Task

Executes one or more 'c3dhall6_log_xxx_task' functions Additional Functions :

• c3dhall6_log_adc_task() - performs and logs adc measurements on all channels
• c3dhall6_log_volt_task() - performs and logs voltage measurements on all channels
• c3dhall6_log_angleRad_task() - performs and logs angle measurements in radians on each die
• c3dhall6_log_angleDeg_task() - performs and logs angle measurements in degrees on each die

void application_task ( void )
{
    c3dhall6_log_angle_deg_task( );
    Delay_ms ( 1000 );
}

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.
