Click library

  • Author : Nenad Filipovic
  • Date : Dec 2021.
  • Type : PWM type

Software Support

We provide a library for the LED Driver 13 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 13 Click driver.

Example Description

This library contains API for LED Driver 13 Click driver.

The demo application is composed of two sections :

Application Init

Initializes the driver and executes the click default configuration which starts the PWM module and sets the LEDs current to minimum.

void application_init ( void )
{
log_cfg_t log_cfg;
leddriver13_cfg_t leddriver13_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
leddriver13_cfg_setup( &leddriver13_cfg );
LEDDRIVER13_MAP_MIKROBUS( leddriver13_cfg, MIKROBUS_1 );
if ( PWM_ERROR == leddriver13_init( &leddriver13, &leddriver13_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( LEDDRIVER13_ERROR == leddriver13_default_cfg ( &leddriver13 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
leddriver13_set_duty_cycle ( &leddriver13, 0.01 );
Delay_ms( 100 );
}

Application Task

This is an example that demonstrates the use of the LED Driver 13 Click boardâ„¢. The app controls the LEDs brightness by changing the PWM duty cycle. The PWM duty cycle percentage will be logged on the USB UART.

void application_task ( void )
{
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 1000.0;
leddriver13_set_duty_cycle ( &leddriver13, duty );
log_printf( &logger, "> Duty: %.1f%%\r\n", duty * 100 );
Delay_ms( 100 );
if ( 30 == 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.LEDDriver13

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.
