LED Driver 10 Click

LED Driver 10 Click is a compact add-on board that simplifies the control of multiple LEDs. This board features the TLC59283, a 16-channel, constant-current sink light-emitting diode (LED) driver with pre-charge FET from Texas Instruments.

Software Support

We provide a library for the LEDDriver10 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 LEDDriver10 Click driver.

Example Description

This example demonstrates the use of LED Driver 10 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver, starts the PWM module and enables all channels.

void application_init ( void )
{
log_cfg_t log_cfg;
leddriver10_cfg_t leddriver10_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
Delay_ms ( 100 );
log_info( &logger, " Application Init " );
// Click initialization.
leddriver10_cfg_setup( &leddriver10_cfg );
LEDDRIVER10_MAP_MIKROBUS( leddriver10_cfg, MIKROBUS_1 );
err_t init_flag = leddriver10_init( &leddriver10, &leddriver10_cfg );
if ( SPI_MASTER_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
leddriver10_pwm_start( &leddriver10 );
log_printf( &logger, " All channels enabled!\r\n" );
log_printf( &logger, " Dimming the LEDs light...\r\n" );
}

Application Task

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 int16_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 10.0;
leddriver10_set_duty_cycle ( &leddriver10, duty );
log_printf( &logger, "> Duty: %u%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
Delay_ms ( 500 );
if ( 10 == 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.LEDDriver10

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.
