Library Description

The library contains a basic functions for using Driver 2 click.

Key functions:

• void driver2_set_sd_pin ( uint8_t state ) - Set SD pin
• void driver2_set_pwm_pin ( uint8_t state ) - Set PWM pin
• uint8_t driver2_get_fb_pin ( void ) - Get FB pin

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO pins.
• Application Initialization - Initializes driver module and sets pwm.
• Application Task - Change the PWM duty cycle every 100ms

void application_task ( )
{
    for ( duty_cycle = 0; duty_cycle < pwm_period; duty_cycle += 25 )
    {
        driver2_pwm_set_duty( duty_cycle );
        Delay_ms( 100 );
    }
    for ( duty_cycle = pwm_period; duty_cycle <= 0; duty_cycle -= 25 )
    {
        driver2_pwm_set_duty( duty_cycle );
        Delay_ms( 100 );
    }
}

Other mikroE Libraries used in the example:

• PWM library
• UART Library

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.
