DC Motor 11 click

DC Motor 11 Click is a brushed DC motor driver with the current limiting and current sensing. It is based on the DRV8830, an integrated H-Bridge driver IC, optimized for motor driving applications.

Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : I2C type

Software Support

We provide a library for the DcMotor11 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for DcMotor11 Click driver.

Standard key functions :

Example key functions :

  • Motor Control

    void dcmotor11_control ( dcmotor11_t *ctx, uint8_t dir, uint8_t speed );

  • Get Fault

    uint8_t dcmotor11_get_fault ( dcmotor11_t *ctx );

  • Interrupt state on the INT pin

    uint8_t dcmotor11_get_interrupt_state ( dcmotor11_t *ctx );

Examples Description

This application is motor driver with the current limiting and current sensing.

The demo application is composed of two sections :

Application Init

Initialization driver init and sets first motor settings.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
DCMOTOR11_MAP_MIKROBUS( cfg, MIKROBUS_1 );
dcmotor11_init( &dcmotor11, &cfg );
dcmotor11_get_fault( &dcmotor11 );
/* Start settings */
}

Application Task

Waits for valid user input and executes functions based on set of valid commands.

void application_task ( void )
{
/* Speed increase */
{
log_printf( &logger, "---- MAX SPEED ---- \r\n" );
}
else
{
log_printf( &logger, "---- Speed increase ---- \r\n" );
log_printf( &logger, " MOTOR SPEED: %d \r\n", motor_speed );
}
Delay_ms( 2000 );
/* Speed decrease */
{
log_printf( &logger, "---- MIN SPEED ---- \r\n" );
}
else
{
log_printf( &logger, "---- Speed decrease ---- \r\n");
log_printf( &logger, " MOTOR SPEED: %d \r\n", motor_speed );
}
Delay_ms( 2000 );
/* Stop / Start */
if( f_motor_state == 1 )
{
log_printf( &logger,"---- Stop Motor!!! ---- \r\n" );
dcmotor11_stop( &dcmotor11 );
}
else
{
log_printf( &logger,"---- Start Motor ---- \r\n" );
}
Delay_ms ( 2000 );
/* Direction - Forward / Backword */
if ( motor_dir == 2 )
{
log_printf( &logger,"---- Direction - [FORWARD] ---- \r\n" );
motor_dir = 1;
}
else
{
log_printf( &logger,"---- Direction - [BACKWARD] ---- \r\n" );
motor_dir = 2;
}
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.DcMotor11

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
