Driver 2 click

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.

Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : PWM type

Software Support

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.

Library Description

This library contains API for Driver2 Click driver.

Standard key functions :

Example key functions :

Example Description

This is an example that demonstrates the use of the Driver 2 Click board.

The demo application is composed of two sections :

Application Init

Initializes driver module and sets PWM.

void application_init ( void ) {
log_cfg_t log_cfg;
driver2_cfg_t driver2_cfg;
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 " );
}

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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Driver2

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.
