Library Description

The library covers all the necessary functions to control Brushless 3 Click board. 
Library performs the communication with the device via I2C driver by writing to registers and by reading from registers. The library has generic read and writes function, the function for the sets default configuration, for set/get speed, for selection mode, for sets the direction of rotation, etc.

Key functions:

• void brushless3_forwardDirection() - Set forward direction of rotation function.
• float brushless3_getSpeed()- Get speed function.
• void brushless3_setDefaultParam() -Set default parameter function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO, I2C, and LOG structures set INT pins as input and RST and PWM pins as output and start to write log.
• Application Initialization - Initializes driver enable's - I2C, set default parameter value.
• Application Task - (code snippet) This is an example which demonstrates the use of Brushless 3 Click board. Read and display float motor frequency value from the DRV10983 sensorless BLDC motor driver on Brushless 3 click board. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for every 3 sec.

void applicationTask() 
{
    velocity = brushless3_getSpeed();
    FloatToStr( velocity, logText );
    ltrim( logText );
    
    mikrobus_logWrite( " Motor freq.: ", _LOG_TEXT );  
    mikrobus_logWrite( logText, _LOG_TEXT );
    mikrobus_logWrite( " Hz", _LOG_LINE );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
    Delay_1sec();

}

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversion

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
