Driver 2 click

Driver 2 Click is a compact add-on board that contains a gate driver with a level-shift technology with an additional Shutdown function. This board features the IR2104S, a high voltage, high-speed power MOSFET and IGBT driver with typical 0.21 A source and 0.36 A sink currents and independent high and low side referenced output channels from Infineon Technologies.

Click library

• Author : Stefan Ilic
• Date : Aug 2021.
• Type : PWM type

Software Support

We provide a library for the Driver2 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 Driver2 Click driver.

Standard key functions :

• driver2_cfg_setup Config Object Initialization function.

void driver2_cfg_setup ( driver2_cfg_t *cfg );

• driver2_init Initialization function.

err_t driver2_init ( driver2_t *ctx, driver2_cfg_t *cfg );

• driver2_default_cfg Click Default Configuration function.

err_t driver2_default_cfg ( driver2_t *ctx );

Example key functions :

• driver2_set_sd_pin Set SD pin.

void driver2_set_sd_pin ( driver2_t *ctx, uint8_t state );

• driver2_set_pwm_pin Set PWM pin.

void driver2_set_pwm_pin ( driver2_t *ctx, uint8_t state );

• driver2_get_fb_pin Get FB pin

uint8_t driver2_get_fb_pin ( driver2_t *ctx );

Example Description

This is an example that demonstrates the use of the Driver 2 Click board.

The demo application is composed of two sections :

Application Init

Initializes driver module and sets PWM.

void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    driver2_cfg_t driver2_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.

    driver2_cfg_setup( &driver2_cfg );
    DRIVER2_MAP_MIKROBUS( driver2_cfg, MIKROBUS_1 );
    err_t init_flag  = driver2_init( &driver2, &driver2_cfg );
    if ( PWM_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    driver2_default_cfg ( &driver2 );

    driver2_set_duty_cycle ( &driver2, 0.0 );
    driver2_pwm_start( &driver2 );

    log_info( &logger, " Application Task " );
}

Application Task

Start motor example with change in motor speed using changes in PWM duty cycle.

void application_task ( void ) {
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;
    
    driver2_set_duty_cycle ( &driver2, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
    
    Delay_ms ( 500 );
    
    if ( 10 == duty_cnt ) {
        duty_inc = -1;
    } else if ( 0 == duty_cnt ) {
        duty_inc = 1;
    }
    duty_cnt += duty_inc;
}

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.Driver2

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. UART terminal is available in all MikroElektronika compilers.
