DC Motor 20 Click

DC Motor 20 Click is a compact add-on board that contains a brushed DC motor driver. This board features the TC78H651AFNG, a dual H-bridge driver for one or two DC brushed motors, which incorporates DMOS with low ON resistance in output transistors from Toshiba Semiconductor.

Click library

  • Author : Stefan Filipovic
  • Date : Oct 2021.
  • Type : GPIO type

Software Support

We provide a library for the DCMotor20 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 DCMotor20 Click driver.

Standard key functions :

  • dcmotor20_cfg_setup Config Object Initialization function.

    void dcmotor20_cfg_setup ( dcmotor20_cfg_t *cfg );
  • dcmotor20_init Initialization function.

    err_t dcmotor20_init ( dcmotor20_t *ctx, dcmotor20_cfg_t *cfg );

Example key functions :

  • dcmotor20_drive_motor This function drives the motor for a certian time specified by time_ms at the desired speed.

    err_t dcmotor20_drive_motor ( dcmotor20_t *ctx, uint8_t speed, uint32_t time_ms );
  • dcmotor20_set_channel_mode This function sets the active channel and mode which will be used by the dcmotor20_drive_motor function.

    err_t dcmotor20_set_channel_mode ( dcmotor20_t *ctx, uint8_t channel, uint8_t mode );
  • dcmotor20_set_standby_mode This function sets the chip to the standby mode which affects both channels.

    void dcmotor20_set_standby_mode ( dcmotor20_t *ctx );

Example Description

This example demonstrates the use of DC Motor 20 Click board by driving the motors in both direction in the span of 14 seconds.

The demo application is composed of two sections :

Application Init

Initializes the driver and sets the Click board to standby mode.


void application_init ( void )
{
    log_cfg_t log_cfg;              /**< Logger config object. */
    dcmotor20_cfg_t dcmotor20_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.
    dcmotor20_cfg_setup( &dcmotor20_cfg );
    DCMOTOR20_MAP_MIKROBUS( dcmotor20_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == dcmotor20_init( &dcmotor20, &dcmotor20_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    dcmotor20_set_standby_mode ( &dcmotor20 );
    log_info( &logger, " Application Task " );
}

Application Task

Drives the motors in the forward direction for 5 seconds, and then switches the direction, with a brake time of 2 seconds between switching the direction. Each step will be logged on the USB UART where you can track the program flow.


void application_task ( void )
{
    log_printf ( &logger, " Driving motors forward...\r\n" );
    dcmotor20_set_channel_mode ( &dcmotor20, DCMOTOR20_CHANNEL_1 | DCMOTOR20_CHANNEL_2, DCMOTOR20_MODE_FORWARD );
    dcmotor20_drive_motor ( &dcmotor20, DCMOTOR20_SPEED_DEFAULT, 5000 );
    log_printf ( &logger, " Pull brake!\r\n" );
    dcmotor20_set_standby_mode ( &dcmotor20 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf ( &logger, " Driving motors in reverse...\r\n" );
    dcmotor20_set_channel_mode ( &dcmotor20, DCMOTOR20_CHANNEL_1 | DCMOTOR20_CHANNEL_2, DCMOTOR20_MODE_REVERSE );
    dcmotor20_drive_motor ( &dcmotor20, DCMOTOR20_SPEED_DEFAULT, 5000 );
    log_printf ( &logger, " Pull brake!\r\n\n" );
    dcmotor20_set_standby_mode ( &dcmotor20 );
    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.DCMotor20

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.

There are many kinds of touch sensors on the market, but every one of them has some unique features that make it stand out from the crowd. TouchKey 3 Click is equipped with seven advanced capacitive sensors, based on the proprietary QTouch® technology. Besides quite a large number of QTouch® capacitive sensor channels, TouchKey 3 Click also offers some additional features, such as the Adjacent Key Suppression (AKS®), a technology that ensures correct button press, even when the touch sensing pads are placed close to each other.
