Brushless 27 click

Brushless 27 Click is a compact add-on board that controls DC brushless motors with any MCU. This board features the TMC6300, a power driver for BLDC/PMSM motors from TRINAMIC. It is a highly efficient low voltage, zero standby driver for 3-phase BLDC/PMSM motors with up to 2A peak current.

Software Support

We provide a library for the Brushless 27 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 Brushless 27 Click driver.

Example Description

This example demonstrates the use of the Brushless 27 click board by driving the

motor in both directions at different speeds.

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;
brushless27_cfg_t brushless27_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
brushless27_cfg_setup( &brushless27_cfg );
BRUSHLESS27_MAP_MIKROBUS( brushless27_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == brushless27_init( &brushless27, &brushless27_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( BRUSHLESS27_ERROR == brushless27_default_cfg ( &brushless27 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Drives the motor in both directions and changes the motor speed approximately every 2 seconds.

The driving direction and speed will be displayed on the USB UART.

void application_task ( void )
{
log_printf ( &logger, "\r\n Driving motor clockwise \r\n" );
for ( uint8_t speed = BRUSHLESS27_SPEED_MIN; speed <= BRUSHLESS27_SPEED_MAX; speed += 20 )
{
log_printf ( &logger, " Speed gain: %u\r\n", ( uint16_t ) speed );
if ( BRUSHLESS27_OK != brushless27_drive_motor ( &brushless27, BRUSHLESS27_DIR_CW, speed, 2000 ) )
{
log_error ( &logger, " Drive motor " );
}
}
Delay_ms ( 1000 );
log_printf ( &logger, "\r\n Driving motor counter-clockwise \r\n" );
for ( uint8_t speed = BRUSHLESS27_SPEED_MIN; speed <= BRUSHLESS27_SPEED_MAX; speed += 20 )
{
log_printf ( &logger, " Speed gain: %u\r\n", ( uint16_t ) speed );
if ( BRUSHLESS27_OK != brushless27_drive_motor ( &brushless27, BRUSHLESS27_DIR_CCW, speed, 2000 ) )
{
log_error ( &logger, " Drive motor " );
}
}
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.Brushless27

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.
