DAC 4 Click

DAC 4 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.

Click Library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

Example Description

This application enables usage of digital to analog converter.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Dac4

Example Key Functions

• dac4_cfg_setup Config Object Initialization function.

void dac4_cfg_setup ( dac4_cfg_t *cfg ); 

• dac4_init Initialization function.

err_t dac4_init ( dac4_t *ctx, dac4_cfg_t *cfg );

• dac4_voltage_reference_set Setting channel voltage reference values

uint8_t dac4_voltage_reference_set ( dac4_t *ctx, uint8_t v_ref_channel_a, uint8_t v_ref_channel_b, uint8_t v_ref_channel_c, uint8_t v_ref_channel_d );

• dac4_gain_set Writing channel gain values

uint8_t dac4_gain_set ( dac4_t *ctx, uint8_t gain_channel_a, uint8_t gain_channel_b, uint8_t gain_channel_c, uint8_t gain_channel_d );

• dac4_data_report Reading channel data and forming reports

uint8_t dac4_data_report ( dac4_t *ctx, dac_channel_setting_t * channel_buffer );

Application Init

Initializes I2C driver, executes general call reset and wake up commands.

void application_init ( void )
{
    log_cfg_t log_cfg;
    dac4_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.

    dac4_cfg_setup( &cfg );
    DAC4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    dac4_init( &dac4, &cfg );
    log_info( &logger, "---- Application ----" );

    Delay_ms ( 500 );
    dac4_general_call_reset( &dac4 );
    Delay_ms ( 500 );
    dac4_general_call_wake_up( &dac4 );
    Delay_ms ( 500 );

    log_printf( &logger, "--- App init done \r\n \r\n" );
}

Application Task

Changes the output voltage of channels every 3 seconds, and displays the channels status on the USB UART.

void application_task ( void )
{
    dac4_channel_report( );
}

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.
