DC Motor 29 Click is a compact add-on board that contains a high-performance DC motor driver. This board features the DRV8245P, an automotive H-Bridge driver with integrated current sense and diagnostic from Texas Instruments. It can be configured as a single full-bridge driver or independent half-bridge driver. The driver offers excellent power handling and thermal capability due to a BiCMOS high power process technology mode, in which it is designed.

  • Author : Stefan Ilic
  • Date : Sep 2023.
  • Type : SPI type

Software Support

We provide a library for the DC Motor 29 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 29 Click driver.

Standard key functions :

  • dcmotor29_cfg_setup Config Object Initialization function.

    void dcmotor29_cfg_setup ( dcmotor29_cfg_t *cfg );
  • dcmotor29_init Initialization function.

    err_t dcmotor29_init ( dcmotor29_t *ctx, dcmotor29_cfg_t *cfg );
  • dcmotor29_default_cfg Click Default Configuration function.

    err_t dcmotor29_default_cfg ( dcmotor29_t *ctx );

Example key functions :

  • dcmotor29_register_write DC Motor 29 data register writing function.

    err_t dcmotor29_register_write ( dcmotor29_t *ctx, uint8_t reg, uint8_t data_in );
  • dcmotor29_port_expander_read DC Motor 29 port ecpander read register function.

    err_t dcmotor29_port_expander_read ( dcmotor29_t *ctx, uint8_t reg, uint8_t *data_out );
  • dcmotor29_drive_motor DC Motor 29 drive motor function.

    err_t dcmotor29_drive_motor ( dcmotor29_t *ctx, uint8_t state );

Example Description

This example demonstrates the use of the DC Motor 29 Click board by driving the motor in both directions with braking and coasting in between.

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;  /**< Logger config object. */
    dcmotor29_cfg_t dcmotor29_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.
    dcmotor29_cfg_setup( &dcmotor29_cfg );
    DCMOTOR29_MAP_MIKROBUS( dcmotor29_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == dcmotor29_init( &dcmotor29, &dcmotor29_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( DCMOTOR29_ERROR == dcmotor29_default_cfg ( &dcmotor29 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

Drives the motor in both directions with coasting and braking in between, every sate is lasting 5 seconds.

void application_task ( void )
{
    dcmotor29_drive_motor( &dcmotor29, DCMOTOR29_DRIVE_MOTOR_CW );
    log_printf( &logger, " Driving motor Clockwise \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    dcmotor29_drive_motor( &dcmotor29, DCMOTOR29_DRIVE_MOTOR_BRAKE );
    log_printf( &logger, " Brake is on \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    dcmotor29_drive_motor( &dcmotor29, DCMOTOR29_DRIVE_MOTOR_CCW );
    log_printf( &logger, " Driving motor counter-clockwise \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    dcmotor29_drive_motor( &dcmotor29, DCMOTOR29_DRIVE_MOTOR_COASTING );
    log_printf( &logger, " Driving motor Coasting \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.DCMotor29

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.

RS232 to I2C Click

0

RS232 to I2C Click is a compact add-on board representing a universal usable RS232 to I2C converter. This board features the ZDU0110RFX, a bridge between a UART port and an I2C bus from Zilog, which at the same time represents the connection between the MCU and the RS232 line driver and receiver, the MAX3232. The ZDU0110RFX provides full-duplex asynchronous communications with a 128 byte FIFO buffer, of which 64 bytes each are allocated to receive and transmit operations. It also contains a 4kbit EEPROM and GPIO with programmable interrupt capability; programmable interrupts and interrupt lines for UART and GPIO notifications.
