DC Motor 29 click

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.

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.

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;
dcmotor29_cfg_t dcmotor29_cfg;
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 )
{
log_printf( &logger, " Driving motor Clockwise \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " Brake is on \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " Driving motor counter-clockwise \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
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.
