LED Flash 3 Click

LED Flash 3 Click is a compact add-on board representing a powerful flash/torch solution. This board features the KTD2691, an inductor-less, single-flash LED driver from Kinetic Technologies. It includes one current source that can drive up to 1.5A of LED flash current or up to 376mA of torch current.

Software Support

We provide a library for the LED Flash 3 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 Flash 3 Click driver.

Example Description

This app demonstrate flash mode on LED Flash 3 Click.

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;
ledflash3_cfg_t ledflash3_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ledflash3_cfg_setup( &ledflash3_cfg );
LEDFLASH3_MAP_MIKROBUS( ledflash3_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == ledflash3_init( &ledflash3, &ledflash3_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( LEDFLASH3_ERROR == ledflash3_default_cfg ( &ledflash3 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task ");
}

Application Task

Turning the LED on for a second and off for another second.

void application_task ( void )
{
ledflash3_strobe_pin( &ledflash3 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}

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.LEDFlash3

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.
