10x10 RGB Click

10x10 RGB Click is a matrix of 100 intelligent RGB elements, forming a 10x10 display screen. These LED elements feature internal logic, which allows them to communicate directly with the MCU.

Software Support

We provide a library for the 10x10RGB 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 10x10RGB Click driver.

Standard key functions :

• c10x10rgb_cfg_setup Config Object Initialization function.

  void c10x10rgb_cfg_setup ( c10x10rgb_cfg_t *cfg ); 

• c10x10rgb_init Initialization function.

  C10X10RGB_RETVAL c10x10rgb_init ( c10x10rgb_t *ctx, c10x10rgb_cfg_t *cfg );

• c10x10rgb_default_cfg Click Default Configuration function.

  void c10x10rgb_default_cfg ( c10x10rgb_t *ctx );

Example key functions :

• c10x10rgb_display_image This function displays an image from the specified demo_image address.

  void c10x10rgb_display_image ( c10x10rgb_t *ctx, const uint32_t *demo_image );

• c10x10rgb_display_byte This function displays the specified byte.

  void c10x10rgb_display_byte ( c10x10rgb_t *ctx, c10x10rgb_byte_t *data_obj );

• c10x10rgb_display_string This function displays the specified string.

  void c10x10rgb_display_string ( c10x10rgb_t *ctx, c10x10rgb_byte_t *data_obj, uint8_t len, uint16_t speed_ms );

Examples Description

This example showcases how to initialize, configure and use the 10x10 RGB Click module. The click has a 10 by 10 RGB LED matrix which can be programmed to show different colors or even images. LED elements that form the matrix communicate by a single line with the host MCU.

The demo application is composed of two sections :

Application Init

This function initializes and configures the Click board.

void application_init ( void )
{
    c10x10rgb_cfg_t cfg;

    //  Click initialization.
    c10x10rgb_cfg_setup( &cfg, &logic_zero, &logic_one );
    C10X10RGB_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c10x10rgb_init( &c10x10rgb, &cfg );

    c10x10rgb_fill_screen( &c10x10rgb, C10X10RGB_COLOR_OFF );
    Delay_ms ( 1000 );
}

Application Task

This function first displays 3 chars { R, G, B }, the string "MIKROE", the company logo and a rainbow in the end.

void application_task ( void )
{
    c10x10rgb_display_byte ( &c10x10rgb, &rgb_data_byte[ 0 ] );
    Delay_ms ( 1000 );
    c10x10rgb_display_byte ( &c10x10rgb, &rgb_data_byte[ 1 ] );
    Delay_ms ( 1000 );
    c10x10rgb_display_byte ( &c10x10rgb, &rgb_data_byte[ 2 ] );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    c10x10rgb_display_string( &c10x10rgb, &scroll_data_obj, scroll_data_len, scroll_speed_ms );
    Delay_ms ( 1000 );
    c10x10rgb_display_image( &c10x10rgb, &MIKROE_IMAGE[ 0 ] );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    c10x10rgb_demo_rainbow( &c10x10rgb, rainbow_brightness, rainbow_speed_ms );
    Delay_ms ( 1000 );
} 

Note

Make sure the logic delays are defined for your system in the c10x10rgb_delays.h file.

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.10x10RGB

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.
