Brushless click

<Brushless click carries Toshiba's TB6575FNG IC for driving 3-phase full-wave Brushless DC motors — which are ideal for powering flying drones. The click is able to safely drive external motors with up to 32V/2A. The board features three pairs of onboard screw terminals. VBAT is for connecting an external 7-32V DC power supply.>

Click library

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

Software Support

We provide a library for the Brushless 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 Brushless Click driver.

Standard key functions :

  • Config Object Initialization function.

    ‍void brushless_cfg_setup ( brushless_cfg_t *cfg );

    - Initialization function.

    ‍BRUSHLESS_RETVAL brushless_init ( brushless_t *ctx, brushless_cfg_t *cfg );

  • Click Default Configuration function.

    ‍void brushless_default_cfg ( brushless_t *ctx );

Example key functions :

  • This function sets the spin direction of the motor to clockwise.

    ‍void brushless_spin_clockwise ( brushless_t *ctx );

    - This function sets the spin direction of the motor to counter clockwise.

    ‍void brushless_spin_counter_clockwise ( brushless_t *ctx );

  • This function reads the digital input of the INT pin.

    ‍uint8_t brushless_read_rotation_speed_sensor_output ( brushless_t *ctx );

    Examples Description

‍This example showcases how to initialize and use the Brushless click. The click has a bru- shless motor driver which controls the work of the motor through the BLDC terminal. In order for this example to work a motor and a power supply are needed.

The demo application is composed of two sections :

Application Init

‍This function initializes and configures the logger and click modules.

{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
Delay_100ms( );
// Click initialization.
BRUSHLESS_MAP_MIKROBUS( cfg, MIKROBUS_1 );
Delay_100ms( );
brushless_init( &brushless, &cfg );
brushless_pwm_start( &brushless );
Delay_1sec( );
}
#define BRUSHLESS_MAP_MIKROBUS(cfg, mikrobus)
Definition: brushless.h:53
void brushless_pwm_start(brushless_t *ctx)
Start PWM module.
BRUSHLESS_RETVAL brushless_init(brushless_t *ctx, brushless_cfg_t *cfg)
Initialization function.
void brushless_cfg_setup(brushless_cfg_t *cfg)
Config Object Initialization function.
void application_init()
Definition: main.c:84
Click configuration structure definition.
Definition: brushless.h:117

Application Task

‍This function drives the motor in both directions increasing and decreasing the speed of the motor.

{
clockwise( );
counter_clockwise( );
}
void application_task()
Definition: main.c:113

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.Brushless

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.
