DC Motor 23 Click

DC Motor 23 Click is a compact add-on board with a brushed DC motor driver. This board features the TB67H480FNG, a dual-channel, H-bridge, brushed DC motor driver from Toshiba Semiconductor. Fabricated with the BiCD process (DMOSFET is used for output power transistor), it covers a wide operating voltage range of 8.2V to 44V with a maximum output current capacity of 2A. It also offers many helpful features that support a robust and reliable operation, like the decay modes selection function, several protection features, and one anomaly detection indicator.

Click library

• Author : Nenad Filipovic
• Date : Jan 2023.
• Type : I2C type

Software Support

We provide a library for the DC Motor 23 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 DC Motor 23 Click driver.

Standard key functions :

• dcmotor23_cfg_setup Config Object Initialization function.

void dcmotor23_cfg_setup ( dcmotor23_cfg_t *cfg );

• dcmotor23_init Initialization function.

err_t dcmotor23_init ( dcmotor23_t *ctx, dcmotor23_cfg_t *cfg );

• dcmotor23_default_cfg Click Default Configuration function.

err_t dcmotor23_default_cfg ( dcmotor23_t *ctx );

Example key functions :

• dcmotor23_set_clockwise DC Motor 23 set clockwise function.

err_t dcmotor23_set_clockwise ( dcmotor23_t *ctx, uint8_t sel_motor );

• dcmotor23_set_counter_clockwise DC Motor 23 set counter clockwise function.

err_t dcmotor23_set_counter_clockwise ( dcmotor23_t *ctx, uint8_t sel_motor );

• dcmotor23_set_decay DC Motor 23 set decay function.

err_t dcmotor23_set_decay ( dcmotor23_t *ctx, uint8_t sel_motor );

Example Description

This example demonstrates the use of DC Motor 23 Click board™. by driving the motors in both direction every 3 seconds.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration which sets the output torque to 100%.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    dcmotor23_cfg_t dcmotor23_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.
    dcmotor23_cfg_setup( &dcmotor23_cfg );
    DCMOTOR23_MAP_MIKROBUS( dcmotor23_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == dcmotor23_init( &dcmotor23, &dcmotor23_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( DCMOTOR23_ERROR == dcmotor23_default_cfg ( &dcmotor23 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf ( &logger, "--------------------------\r\n" );
}

Application Task

This example demonstrates the use of the DC Motor 23 Click board™. Drives the motors in the clockwise direction, after that decay the motors with a 3 seconds delay then switches to the counter-clockwise direction, and decay the motors with a 3 seconds delay. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{    
    if ( DCMOTOR23_OK == dcmotor23_set_clockwise( &dcmotor23, DCMOTOR23_SEL_OUT_A ) )
    {
        log_printf ( &logger, " OUTA: Clockwise\r\n" );
    }
    if ( DCMOTOR23_OK == dcmotor23_set_clockwise( &dcmotor23, DCMOTOR23_SEL_OUT_B ) )
    {
        log_printf ( &logger, " OUTB: Clockwise\r\n\n" );
    }
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    if ( DCMOTOR23_OK == dcmotor23_set_decay( &dcmotor23, DCMOTOR23_SEL_OUT_A ) )
    {
        log_printf ( &logger, " OUTA: Decay\r\n" );
    }
    if ( DCMOTOR23_OK == dcmotor23_set_decay( &dcmotor23, DCMOTOR23_SEL_OUT_B ) )
    {
        log_printf ( &logger, " OUTB: Decay\r\n\n" );
    }
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    if ( DCMOTOR23_OK == dcmotor23_set_counter_clockwise( &dcmotor23, DCMOTOR23_SEL_OUT_A ) )
    {
        log_printf ( &logger, " OUTA: Counter-Clockwise\r\n" );
    }
    if ( DCMOTOR23_OK == dcmotor23_set_counter_clockwise( &dcmotor23, DCMOTOR23_SEL_OUT_B ) )
    {
        log_printf ( &logger, " OUTB: Counter-Clockwise\r\n\n" );
    }
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    if ( DCMOTOR23_OK == dcmotor23_set_decay( &dcmotor23, DCMOTOR23_SEL_OUT_A ) )
    {
        log_printf ( &logger, " OUTA: Decay\r\n" );
    }
    if ( DCMOTOR23_OK == dcmotor23_set_decay( &dcmotor23, DCMOTOR23_SEL_OUT_B ) )
    {
        log_printf ( &logger, " OUTB: Decay\r\n\n" );
    }
    log_printf ( &logger, "--------------------------\r\n" );
    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.DCMotor23

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.
