- Type : I2C type
Software Support
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.
Library Description
This library contains API for LightTemp Click driver.
Standard key functions :
- 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 );
Example key functions :
- 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 );
Examples Description
This application controls light intensity of LEDs.
The demo application is composed of two sections :
Application Init
Initialization driver init and pwm init for all LED's
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
Delay_ms( 100 );
Delay_ms( 100 );
}

Application Task
Increases/decreases light intensity.

{
Delay_ms( 500 );
}
Delay_ms( 1000 );
log_printf( &logger, ">>> Decreasing LEDs light intensity \r\n" );
for ( duty_cycle = 0.5; duty_cycle > 0; duty_cycle -= 0.1 )
{
Delay_ms( 500 );
}
Delay_ms( 1000 );
}
void lighttemp_led1_pwm_stop(lighttemp_t *ctx)

Start PWM module for LED1.
void lighttemp_led2_pwm_stop(lighttemp_t *ctx)
Stop PWM module for LED2.
void lighttemp_led2_pwm_start(lighttemp_t *ctx)
Start PWM module for LED2.
void lighttemp_led1_set_duty_cycle(lighttemp_t *ctx, float duty_cycle)
Generic sets PWM duty cycle for LED1.

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.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.LightTemp
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.
