Light Temp Click is a dual-channel LED driver, designed to be used in tunable Smart Connected Lighting (SCL) applications.
We provide a library for the LightTemp 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for LightTemp Click driver.
Config Object Initialization function.
void lighttemp_cfg_setup ( lighttemp_cfg_t *cfg );
Initialization function.
LIGHTTEMP_RETVAL lighttemp_init ( lighttemp_t ctx, lighttemp_cfg_t cfg );
Get INT pin state
uint8_t lighttemp_get_interrupt_state ( lighttemp_t *ctx );
Get voltage
uint16_t lighttemp_get_pg_voltage ( lighttemp_t *ctx );
Start PW2 module.
void lighttemp_cs_set_state( lighttemp_t *ctx, uint8_t state );
This application controls light intensity of LEDs.
The demo application is composed of two sections :
Initialization driver init and pwm init for all LED's
void application_init ( void )
{
log_cfg_t log_cfg;
lighttemp_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
Delay_ms ( 100 );
// Click initialization.
lighttemp_cfg_setup( &cfg );
LIGHTTEMP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
lighttemp_init( &lighttemp, &cfg );
lighttemp_led1_set_duty_cycle ( &lighttemp, 0.0 );
lighttemp_led2_set_duty_cycle ( &lighttemp, 0.0 );
log_info( &logger, "---- Application Task ----" );
Delay_ms ( 500 );
}
This is an example that demonstrates the use of the Light Temp Click board. This example shows the automatic control of the LED light intensity, the first intensity of light is rising and then the intensity of light is falling. Results are being sent to the Usart Terminal where you can track their changes.
void application_task ( void )
{
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 10.0;
lighttemp_led1_set_duty_cycle ( &lighttemp, duty );
lighttemp_led2_set_duty_cycle ( &lighttemp, duty );
lighttemp_led1_pwm_start( &lighttemp );
lighttemp_led2_pwm_start( &lighttemp );
log_printf( &logger, "Duty: %d%%\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 form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
