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.
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.
This library contains API for DCMotor15 Click driver.
dcmotor15_cfg_setup
Config Object Initialization function.
void dcmotor15_cfg_setup ( dcmotor15_cfg_t *cfg );
dcmotor15_init
Initialization function.
DCMOTOR15_RETVAL dcmotor15_init ( dcmotor15_t *ctx, dcmotor15_cfg_t *cfg );
dcmotor15_default_cfg
Click Default Configuration function.
void dcmotor15_default_cfg ( dcmotor15_t *ctx );
dcmotor15_forward
This function drives the motor forward.
void dcmotor15_forward ( dcmotor15_t *ctx );
dcmotor15_reverse
This function drives the motor in reverse.
void dcmotor15_reverse ( dcmotor15_t *ctx );
dcmotor15_get_current
This function reads the motor current consumption by performing analog to digital read of IPR pin.
float dcmotor15_get_current ( dcmotor15_t *ctx, uint16_t num_of_conv );
This example demonstrates the use of DC Motor 15 Click board.
The demo application is composed of two sections :
Initializes the driver and makes an initial log.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
dcmotor15_cfg_t dcmotor15_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 );
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 " );
}
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 );
}

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.
