Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : SPI type

Software Support

We provide a library for the DigiPot4 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 DigiPot4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void digipot4_cfg_setup ( digipot4_cfg_t *cfg );

  • Initialization function.

    DIGIPOT4_RETVAL digipot4_init ( digipot4_t ctx, digipot4_cfg_t cfg );

  • Click Default Configuration function.

    void digipot4_default_cfg ( digipot4_t *ctx );

Example key functions :

  • This function writes data in wiper register and NV register.

    void digipot4_write_reg ( digipot4_t *ctx, uint8_t reg, uint16_t value );

  • This function is used to copy the data from the wipers to the NV memory and from the NV memory it wipers.

    void digipot4_copy_reg ( digipot4_t *ctx, uint8_t reg );

Examples Description

This application is a digitally controlled dual potentiometer.

The demo application is composed of two sections :

Application Init

Driver intialization


void application_init ( void )
{
    log_cfg_t log_cfg;
    digipot4_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 ----" );

    digipot4_cfg_setup( &cfg );
    DIGIPOT4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    digipot4_init( &digipot4, &cfg );
}

Application Task

Set the wiper position.


void application_task ( void )
{

    digipot4_write_reg( &digipot4, DIGIPOT4_WIPER_REG_1, 0 );
    digipot4_write_reg( &digipot4, DIGIPOT4_WIPER_REG_2, 0 );
    Delay_1sec( );
    digipot4_write_reg( &digipot4, DIGIPOT4_WIPER_REG_1, 512 );
    digipot4_write_reg( &digipot4, DIGIPOT4_WIPER_REG_2, 512 );
    Delay_1sec( );
    digipot4_write_reg( &digipot4, DIGIPOT4_WIPER_REG_1, 1023 );
    digipot4_write_reg( &digipot4, DIGIPOT4_WIPER_REG_2, 1023 );
    Delay_1sec( );
}  

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.DigiPot4

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.

UART MUX 4 Click is a compact add-on board that switches the UART pins (RX and TX) from the mikroBUS™ socket to one of the two available outputs. This board features the 74HC4066D, a quad single-pole, single-throw analog switch from Nexperia. The UART MUX 4 Click allows you to switch from one multiplexed UART to another easily, but not both simultaneously.
