Click library

  • Author : Stefan Ilic
  • Date : Jun 2021.
  • Type : SPI type

Software Support

We provide a library for the DigiPot2 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for DigiPot2 Click driver.

Standard key functions :

  • digipot2_cfg_setup Config Object Initialization function.

    void digipot2_cfg_setup ( digipot2_cfg_t *cfg );
  • digipot2_init Initialization function.

    err_t digipot2_init ( digipot2_t *ctx, digipot2_cfg_t *cfg );

Example key functions :

  • digipot2_set_wiper_positions The function sets 8-bit wiper positions data.

    void digipot2_set_wiper_positions ( digipot2_t *ctx, uint8_t wiper_pos );
  • digipot2_convert_output The function convert 10-bit ADC value to volatage reference.

    float digipot2_convert_output ( uint16_t adc_val, float v_ref );

Example Description

The demo application changes the resistance using DIGI POT 2 Click.

The demo application is composed of two sections :

Application Init

Initializes SPI and LOG modules.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    digipot2_cfg_t digipot2_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 );
    log_info( &logger, " Application Init " );

    // Click initialization.

    digipot2_cfg_setup( &digipot2_cfg );
    DIGIPOT2_MAP_MIKROBUS( digipot2_cfg, MIKROBUS_1 );
    err_t init_flag  = digipot2_init( &digipot2, &digipot2_cfg );
    if ( SPI_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    log_printf( &logger, "----------------\r\n" );
    log_printf( &logger, " DIGI POT 2 Click\r\n" );
    log_printf( &logger, "----------------\r\n" );
}

Application Task

This is an example which demonstrates the use of DIGI POT 2 Click board. Increments the wiper position by 10 positions every 5 seconds.


void application_task ( void ) {
    for ( uint16_t n_cnt = 127; n_cnt < 255; n_cnt += 10 ) {
        wiper_pos = ( uint8_t ) n_cnt;
        digipot2_set_wiper_positions( &digipot2, wiper_pos );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.DigiPot2

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.

8x8 R Click is a 64 LED matrix display Click board™, composed of SMD LEDs organized in 8 rows by 8 columns. It has a digital brightness control in 16 steps, it can control every LED in the display matrix independently, it blanks the display on power up to eliminate glitches and it requires a single resistor to control the current through all the LEDs at once, which simplifies the design. 8x8 R Click uses a fast SPI communication protocol, allowing fast display response and no lag.8x8 R Click is an add-on board in mikroBUS form factor.
