Software Support

We provide a library for the LED Driver 14 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 LED Driver 14 Click driver.

Example Description

This example demonstrates the use of LED Driver 14 click board by controlling the brightness of LEDs by changing the PWM Duty Cycle.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
leddriver14_cfg_t leddriver14_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
leddriver14_cfg_setup( &leddriver14_cfg );
LEDDRIVER14_MAP_MIKROBUS( leddriver14_cfg, MIKROBUS_1 );
err_t init_flag = leddriver14_init( &leddriver14, &leddriver14_cfg );
if ( ( I2C_MASTER_ERROR == init_flag ) || ( PWM_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( LEDDRIVER14_ERROR == leddriver14_default_cfg ( &leddriver14 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Adjusts the LEDs' brightness by changing the PWM duty cycle every 500ms. A duty cycle value is being displayed on the USB UART.

void application_task ( void )
{
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 10.0;
leddriver14_set_duty_cycle ( &leddriver14, duty );
log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
if ( 10 == duty_cnt )
{
duty_inc = -1;
}
else if ( 0 == duty_cnt )
{
duty_inc = 1;
}
duty_cnt += duty_inc;
if ( !leddriver14_get_int_pin ( &leddriver14 ) )
{
log_info ( &logger, " Abnormality such as LED Open or the OUTx pin short circuit occured " );
}
Delay_ms( 500 );
}

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.LEDDriver14

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.
