Library Description

The library contains a basic functions for using LED Driver 8 click.

Key functions:

• void leddriver8_set_mode_register( uint8_t mode_1, uint8_t mode_2 ) - Function for set mode registers
• void leddriver8_set_output_gain ( uint8_t num_led, uint8_t value ) - Functions for set output gain
• void leddriver8_set_brightness ( uint8_t num_led, uint8_t value ) - Functions for set Brightness

Examples description

The application is composed of three sections :

• System Initialization - Initialization SPI module and all necessary GPIO pins
• Application Initialization - Initialization driver init and sets module for working
• Application Task - Changes brightness on all LEDs. Controls are blinking on one LED.

void application_task ( )
{
    uint8_t cnt;
    for( cnt = 0; cnt < 0xFF; cnt++ )
    {
        leddriver8_set_brightness( LEDDRIVER8_BRIGHTNESS_ALL_LED, cnt );
        Delay_ms( 15 );
    }
    
    for( cnt = 0; cnt < 5; cnt++ )
    {
       leddriver8_set_brightness( LEDDRIVER8_LED_0, 200 );
       Delay_ms( 1000 );
       leddriver8_set_brightness( LEDDRIVER8_LED_0, 0 );
       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. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
