Driver click

Driver Click features an IC with seven integrated high-current sink drivers, which can be used to drive a wide range of loads via simple parallel interface. These integrated drivers use high-efficiency MOSFETs for improved thermal performance.

Click library

• Author : MikroE Team
• Date : jan 2020.
• Type : GPIO type

Software Support

We provide a library for the Driver 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 Driver Click driver.

Standard key functions :

• Config Object Initialization function.

  void driver_cfg_setup ( driver_cfg_t *cfg );

• Initialization function.

  DRIVER_RETVAL driver_init ( driver_t ctx, driver_cfg_t cfg );

Example key functions :

• IN1 Set function.

  void driver_set_in1 ( driver_t *ctx, uint8_t state );

• IN2 Set function.

  void driver_set_in2 ( driver_t *ctx, uint8_t state );

• IN3 Set function.

  void driver_set_in3 ( driver_t *ctx, uint8_t state );

Examples Description

This application offering a nine-pole spring terminal that can be used to implement and realize a wide range of different applications

The demo application is composed of two sections :

Application Init

Initializes GPIO driver and selects which inputs will be set in operation. Bits from 0 to 6 (selectIN) select inputs from IN1 to IN7, respectively.

void application_init ( void )
{
    log_cfg_t log_cfg;
    driver_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.

    driver_cfg_setup( &cfg );
    DRIVER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    driver_init( &driver, &cfg );
}

Application Task

Performs cycles in which selected inputs will be turned on for pulseWidth delay time one by one. When one input is turned on, it will be turned off after desired delay time before the next input be turned on.

void application_task ( void )
{
    uint8_t select_in;
    uint8_t temp;
    uint8_t count;

    select_in = 0x7F;
    temp = 1;

    for (count = 0; count < 7; count++)
    {
        switch ( select_in & temp )

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.Driver

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.
