Click library

  • Author : Jovan Stajkovic
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Dac 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Dac Click driver.

Standard key functions :

  • Config Object Initialization function.

    void dac_cfg_setup ( dac_cfg_t *cfg );

  • Initialization function.

    DAC_RETVAL dac_init ( dac_t ctx, dac_cfg_t cfg );

Example key functions :

  • This function is used to set output voltage in percents.

    void dac_set_voltage_pct ( dac_t *ctx, uint8_t v_out_pct );

  • This function is used to set output voltage.

    void dac_set_voltage ( dac_t *ctx, uint16_t v_out );

Examples Description

This demo example sends digital signal to the outputs and converts it to analog.

The demo application is composed of two sections :

Application Init

Initializes driver, SPI communication and LOG.


void application_init ( void )
{
    log_cfg_t log_cfg;
    dac_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_printf( &logger, "---- Application Init ----\r\n" );

    //  Click initialization.

    dac_cfg_setup( &cfg );
    DAC_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    dac_init( &dac, &cfg );
}

Application Task

Sends different values( form 0 to 4095 with step 1000 ) to output and prints expected measurement.


void application_task ( void )
{
    for ( dac_val = 0; dac_val <= DAC_RESOLUTION; dac_val += DAC_STEP_VALUE )
    {
        dac_set_voltage( &dac, dac_val );
        dac_val *= DAC_CALIB_VAL_1;
        dac_val /= DAC_CALIB_VAL_2;
        log_printf( &logger, " Current DAC Value: %d mV \r\n", dac_val );

        log_printf( &logger, "----------------------------------\r\n" );

        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Dac

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
