DC Motor 18 Click is a compact add-on board that contains a brushed DC motor driver. This board features the TB9051FTG, an automotive PWM-type single-channel H-Bridge DC brushed motor driver from Toshiba Semiconductor.
We provide a library for the DCMotor18 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.
This library contains API for DCMotor18 Click driver.
dcmotor18_cfg_setup
Config Object Initialization function.
void dcmotor18_cfg_setup ( dcmotor18_cfg_t *cfg );
dcmotor18_init
Initialization function.
err_t dcmotor18_init ( dcmotor18_t *ctx, dcmotor18_cfg_t *cfg );
dcmotor18_default_cfg
Click Default Configuration function.
err_t dcmotor18_default_cfg ( dcmotor18_t *ctx );
dcmotor18_set_speed_percentage
Set speed output percentage.
err_t dcmotor18_set_speed_percentage ( dcmotor18_t *ctx, float speed_percentage );
dcmotor18_set_enable
Set enable pin state.
void dcmotor18_set_enable ( dcmotor18_t *ctx, uint8_t state );
dcmotor18_read_an_pin_current
Read AN pin current.
err_t dcmotor18_read_an_pin_current ( dcmotor18_t *ctx, float *data_out );
This example application showcases ability of Click board to control DC motors using PWM modulation in both directions and different speeds.
The demo application is composed of two sections :
Initialization of MCU communication modules (PWM, ADC, UART) and additioal gpio for control of the device. Then sets default configuration that enables device to control the DC motor.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
dcmotor18_cfg_t dcmotor18_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
dcmotor18_cfg_setup( &dcmotor18_cfg );
DCMOTOR18_MAP_MIKROBUS( dcmotor18_cfg, MIKROBUS_1 );
err_t init_flag = dcmotor18_init( &dcmotor18, &dcmotor18_cfg );
if ( PWM_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
dcmotor18_default_cfg ( &dcmotor18 );
log_info( &logger, " Application Task " );
Delay_ms ( 500 );
}
Drives motor in one direction from 0 to 100% of the speed using PWM, and then returns it back to 0. Then changes the rotation direction and repeats the process of increasing and decreasing acceleration.
void application_task ( void )
{
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float speed = duty_cnt / 10.0;
static uint8_t direction = 1;
dcmotor18_set_direction( &dcmotor18, direction );
dcmotor18_set_speed_percentage ( &dcmotor18, speed );
if ( dcmotor18.direction )
{
log_printf( &logger, "<<< " );
}
else
{
log_printf( &logger, ">>> " );
}
log_printf( &logger, "Speed: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
if ( 10 == duty_cnt )
{
duty_inc = -1;
}
else if ( 0 == duty_cnt )
{
duty_inc = 1;
direction = !direction;
}
duty_cnt += duty_inc;
Delay_ms ( 1000 );
}

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.
