DC Motor 26 click

‍DC Motor 26 Click is a compact add-on board with a brushed DC motor driver. This board features the TB9053FTG, a PWM-type, dual-channel, H-bridge, brushed DC motor driver from Toshiba Semiconductor. The TB9053FTG is rated for an operating voltage range from 4.5V to 28V, with the motor controlled directly through a PWM signal or SPI serial interface. In addition, this driver allows a dual configuration with two motors with 5A current ratings per channel or one 10A channel drive in a Parallel mode of operation. It also has complete diagnostic and protection capabilities supporting robust and reliable operation.

• Author : Stefan Filipovic
• Date : Mar 2023.
• Type : SPI type

Software Support

We provide a library for the DC Motor 26 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 26 Click driver.

Standard key functions :

• dcmotor26_cfg_setup Config Object Initialization function.

  void dcmotor26_cfg_setup ( dcmotor26_cfg_t *cfg );

• dcmotor26_init Initialization function.

  err_t dcmotor26_init ( dcmotor26_t *ctx, dcmotor26_cfg_t *cfg );

• dcmotor26_default_cfg Click Default Configuration function.

  err_t dcmotor26_default_cfg ( dcmotor26_t *ctx );

Example key functions :

• dcmotor26_get_motor_current DC Motor 26 get motor current function.

  err_t dcmotor26_get_motor_current ( dcmotor26_t *ctx, float *current );

• dcmotor26_set_ch1_operation_mode DC Motor 26 set ch1 operation mode function.

  err_t dcmotor26_set_ch1_operation_mode ( dcmotor26_t *ctx, uint8_t mode );

• dcmotor26_set_cm_sel_pin DC Motor 26 set cm sel pin function.

  err_t dcmotor26_set_cm_sel_pin ( dcmotor26_t *ctx, uint8_t state );

Example Description

‍This example demonstrates the use of DC Motor 26 click board by controlling the speed

of DC motor over PWM duty cycle as well as displaying the motor current consumption.

The demo application is composed of two sections :

Application Init

‍Initializes the driver and performs the click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    dcmotor26_cfg_t dcmotor26_cfg;  
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    dcmotor26_cfg_setup( &dcmotor26_cfg );
    DCMOTOR26_MAP_MIKROBUS( dcmotor26_cfg, MIKROBUS_1 );
    if ( DCMOTOR26_OK != dcmotor26_init( &dcmotor26, &dcmotor26_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( DCMOTOR26_OK != dcmotor26_default_cfg ( &dcmotor26 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

‍Changes the operation mode and motor speed by setting the PWM duty cycle and then calculates

the motor current consumption for that speed. All data is being logged on the USB UART where you can track changes.

void application_task ( void )
{
    if ( DCMOTOR26_OK == dcmotor26_set_ch1_operation_mode ( &dcmotor26, DCMOTOR26_MODE_OUTPUT_OFF ) )
    {
        log_printf ( &logger, " MODE: OFF\r\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
    if ( DCMOTOR26_OK == dcmotor26_set_ch1_operation_mode ( &dcmotor26, DCMOTOR26_MODE_FORWARD ) )
    {
        dcmotor26_set_cm_sel_pin ( &dcmotor26, DCMOTOR26_PIN_LOW_LEVEL );
        for ( uint16_t duty = 0; duty <= DCMOTOR26_CONFIG56_DUTY_PERIOD_MAX; duty += 100 )
        {
            float current;
            log_printf ( &logger, " MODE: FORWARD\r\n" );
            if ( DCMOTOR26_OK == dcmotor26_set_ch1_duty_period ( &dcmotor26, duty ) )
            {
                log_printf ( &logger, " Duty: %u\r\n", duty );
            }
            if ( DCMOTOR26_OK == dcmotor26_get_motor_current ( &dcmotor26, &current ) )
            {
                log_printf ( &logger, " Current: %.3f A\r\n\n", current );
            }
            Delay_ms ( 500 );
        }
    }
    if ( DCMOTOR26_OK == dcmotor26_set_ch1_operation_mode ( &dcmotor26, DCMOTOR26_MODE_BRAKE ) )
    {
        log_printf ( &logger, " MODE: BRAKE\r\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }
    if ( DCMOTOR26_OK == dcmotor26_set_ch1_operation_mode ( &dcmotor26, DCMOTOR26_MODE_REVERSE ) )
    {
        dcmotor26_set_cm_sel_pin ( &dcmotor26, DCMOTOR26_PIN_HIGH_LEVEL );
        for ( uint16_t duty = 0; duty <= DCMOTOR26_CONFIG56_DUTY_PERIOD_MAX; duty += 100 )
        {
            float current;
            log_printf ( &logger, " MODE: REVERSE\r\n" );
            if ( DCMOTOR26_OK == dcmotor26_set_ch1_duty_period ( &dcmotor26, duty ) )
            {
                log_printf ( &logger, " Duty: %u\r\n", duty );
            }
            if ( DCMOTOR26_OK == dcmotor26_get_motor_current ( &dcmotor26, &current ) )
            {
                log_printf ( &logger, " Current: %.3f A\r\n\n", current );
            }
            Delay_ms ( 500 );
        }
    }
}

Note

‍The click board swiches should be set as follows: SW 1-2-3-4 : H-H-L-L

This sets the click board as a SPI controlled single-channel device so the motor should be connected to OUT1/2 and OUT3/4.

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.DCMotor26

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.
