DC Motor 15 click

DC Motor 15 Click is a compact add-on board that contains a motor driver with current sense and regulation. This board features the DRV8874, an integrated motor driver with N-channel H-bridge, charge pump, current sensing, and adjustment from Texas Instruments.

Software Support

We provide a library for the DCMotor15 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 DCMotor15 Click driver.

Example Description

This example demonstrates the use of DC Motor 15 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and makes an initial log.

void application_init ( void )
{
log_cfg_t log_cfg;
dcmotor15_cfg_t dcmotor15_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
Delay_ms( 100 );
log_info( &logger, " Application Init " );
// Click initialization.
dcmotor15_cfg_setup( &dcmotor15_cfg );
DCMOTOR15_MAP_MIKROBUS( dcmotor15_cfg, MIKROBUS_1 );
if ( ADC_ERROR == dcmotor15_init( &dcmotor15, &dcmotor15_cfg ) )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
dcmotor15_default_cfg ( &dcmotor15 );
log_info( &logger, " Application Task " );
}

Application Task

Drives the motor in the forward direction for 5 seconds, then pulls brake for 2 seconds, and after that drives it in the reverse direction for 5 seconds, and finally, disconnects the motor for 2 seconds. It will also calculates and displays the motor current consumption. Each step will be logged on the USB UART where you can track the program flow.

void application_task ( void )
{
log_printf( &logger, " The motor turns forward! \r\n" );
dcmotor15_forward( &dcmotor15 );
display_current ( &dcmotor15, RUN_PERIOD );
log_printf( &logger, " Pull brake! \r\n" );
dcmotor15_brake( &dcmotor15 );
display_current ( &dcmotor15, IDLE_PERIOD );
log_printf( &logger, " The motor turns in reverse! \r\n" );
dcmotor15_reverse( &dcmotor15 );
display_current ( &dcmotor15, RUN_PERIOD );
log_printf( &logger, " The motor is disconnected (High-Z)! \r\n" );
dcmotor15_stop( &dcmotor15 );
display_current ( &dcmotor15, IDLE_PERIOD );
}

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.DCMotor15

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.
