Click library

Software Support

We provide a library for the Color7 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 Color7 Click driver.

Standard key functions :

Example key functions :

Examples Description

Demo application reads and detects colors - detected color logs on USBUART.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Settings the click in the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
COLOR7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
color7_init( &color7, &cfg );
color7_default_cfg( &color7 );
log_info( &logger, "---- Start measurement ----" );
}

Application Task

Reads light color and checks which color of light is detected by the sensor If the light color is detected, the detected color message is logged on the USBUART.

void application_task ( void )
{
uint8_t color;
// Task implementation.
color = color7_get_color( &color7 );
switch( color )
{
case 1:
{
log_printf( &logger, "--- Color: ORANGE \r\n" );
break;
}
case 2:
{
log_printf( &logger, "--- Color: RED \r\n" );
break;
}
case 3:
{
log_printf( &logger, "--- Color: PINK \r\n" );
break;
}
case 4:
{
log_printf( &logger, "--- Color: PURPLE \r\n" );
break;
}
case 5:
{
log_printf( &logger, "--- Color: BLUE \r\n" );
break;
}
case 6:
{
log_printf( &logger, "--- Color: CYAN \r\n" );
break;
}
case 7:
{
log_printf( &logger, "--- Color: GREEN \r\n" );
break;
}
case 8:
{
log_printf( &logger, "--- Color: YELLOW \r\n" );
break;
}
}
Delay_100ms();
}

Note

Light source must be pointed towards sensor in order for sensor to detect light source color correctly. We used the HSL color palette on the monitor as an example.

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.
