We provide a library for the Brushless7 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

Library provides functions for controlling brushless motor. It has functions for communicating with device with I2C module, and controlling pins. There are function for controlling device over couple of modes.

Key functions :

• void brushless7_generic_write ( uint8_t reg_adr, uint8_t tx_data ) - Function for writing one byte of data to device
• uint8_t brushless7_generic_read ( uint8_t reg_adr ) - Function for reading one byte of data from device
• void brushless7_default_config ( void ) - Function for setting default configuration of device

Examples Description

The application is composed of three sections :

• System Initialization - Initialization of communication module
• Application Initialization - Setts default configuration and sets parameters for selected mode
• Application Task - Setts 3 different speed of motor in span of 20 seconds

void application_task ( )
{
    if ( BRUSHLESS7_CTRL_TYPE_DUTY == demo_type_data )
    {
        mikrobus_logWrite( " ----- 20 ----- ", _LOG_LINE );
        stop_start();
        brushless7_change_duty( 20 );
        Delay_ms( 20000 );
        mikrobus_logWrite( " ----- 40 ----- ", _LOG_LINE );
        stop_start();
        brushless7_change_duty( 40 );
        Delay_ms( 20000 );
        mikrobus_logWrite( " ----- 8 ----- ", _LOG_LINE );
        stop_start();
        brushless7_change_duty( 8 );
        Delay_ms( 20000 );
    }
    else if ( BRUSHLESS7_CTRL_TYPE_RPM == demo_type_data )
    {
        mikrobus_logWrite( " ----- 400 ----- ", _LOG_LINE );
        stop_start();
        brushless7_start_rpm( 400 );
        Delay_ms( 20000 );
        mikrobus_logWrite( " ----- 1000 ----- ", _LOG_LINE );
        stop_start();
        brushless7_start_rpm( 1000 );
        Delay_ms( 20000 );
        mikrobus_logWrite( " ----- 100 ----- ", _LOG_LINE );
        stop_start();
        brushless7_start_rpm( 100 );
        Delay_ms( 20000 );
    }
}

Additional Functions :

• void stop_start ( ) - Funcnction stops motor and then restores previous mode of working

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• I2C
• UART

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.
