Driver 2 Click is a compact add-on board that contains a gate driver with a level-shift technology with an additional Shutdown function. This board features the IR2104S, a high voltage, high-speed power MOSFET and IGBT driver with typical 0.21 A source and 0.36 A sink currents and independent high and low side referenced output channels from Infineon Technologies.

Driver 2 Click is a compact add-on board that contains a gate driver with a level-shift technology with an additional Shutdown function. This board features the IR2104S, a high voltage, high-speed power MOSFET and IGBT driver with typical 0.21 A source and 0.36 A sink currents and independent high and low side referenced output channels from Infineon Technologies.
We provide a library for the Driver2 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 Driver2 Click driver.
driver2_cfg_setup
Config Object Initialization function.
void driver2_cfg_setup ( driver2_cfg_t *cfg );
driver2_init
Initialization function.
err_t driver2_init ( driver2_t *ctx, driver2_cfg_t *cfg );
driver2_default_cfg
Click Default Configuration function.
err_t driver2_default_cfg ( driver2_t *ctx );
driver2_set_sd_pin
Set SD pin.
void driver2_set_sd_pin ( driver2_t *ctx, uint8_t state );
driver2_set_pwm_pin
Set PWM pin.
void driver2_set_pwm_pin ( driver2_t *ctx, uint8_t state );
driver2_get_fb_pin
Get FB pin
uint8_t driver2_get_fb_pin ( driver2_t *ctx );
This is an example that demonstrates the use of the Driver 2 Click board.
The demo application is composed of two sections :
Initializes driver module and sets PWM.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
driver2_cfg_t driver2_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.
driver2_cfg_setup( &driver2_cfg );
DRIVER2_MAP_MIKROBUS( driver2_cfg, MIKROBUS_1 );
err_t init_flag = driver2_init( &driver2, &driver2_cfg );
if ( PWM_ERROR == init_flag ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
driver2_default_cfg ( &driver2 );
driver2_set_duty_cycle ( &driver2, 0.0 );
driver2_pwm_start( &driver2 );
log_info( &logger, " Application Task " );
}
Start motor example with change in motor speed using changes in PWM duty cycle.
void application_task ( void ) {
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 10.0;
driver2_set_duty_cycle ( &driver2, duty );
log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
Delay_ms ( 500 );
if ( 10 == duty_cnt ) {
duty_inc = -1;
} else if ( 0 == duty_cnt ) {
duty_inc = 1;
}
duty_cnt += duty_inc;
}
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.

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.
CapSense click add-on board features a capacitive sensing module CY8C201A0 which takes human body capacitance as an input and directly provides the real time sensor information via I2C output.
[Learn More]Opto Encoder 2 click is a linear incremental optical sensor/encoder click which can be used for the movement or rotation encoding. Encoders of this type are widely used for many applications, which involve precise detection of the position, speed, or rotational angle of an object.
[Learn More]Hall Current 18 Click is a compact add-on board that contains a precise solution for AC/DC current sensing. This board features the MCS1806, an isolated Hall-effect current sensor from MPS. The sensor is immune to external magnetic fields via differential sensing and has no magnetic hysteresis. The MCS1806 features galvanic isolation between the pins of the primary conductive path and the sensor leads, allowing it to replace optoisolators and other isolation devices.
