10x10 RGB 2 Click

10x10 RGB 2 Click is a compact add-on board designed for creating vibrant LED displays and lighting solutions. This board features the IN-PC20TBT5R5G5B, an RGB LED with an advanced IC for seamless operation from Inolux. The board features a 10x10 matrix of "smart" RGB LEDs capable of dual-wire transmission and a sophisticated control circuit for dynamic color rendering. It incorporates CMOS technology for low power consumption and supports 256 grayscale levels for precise PWM dimming, along with 32 levels of brightness control.

Click library

• Author : Stefan Filipovic
• Date : Nov 2023.
• Type : SPI type

Software Support

We provide a library for the 10x10 RGB 2 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 10x10 RGB 2 Click driver.

Standard key functions :

• c10x10rgb2_cfg_setup Config Object Initialization function.

  void c10x10rgb2_cfg_setup ( c10x10rgb2_cfg_t *cfg );

• c10x10rgb2_init Initialization function.

  err_t c10x10rgb2_init ( c10x10rgb2_t *ctx, c10x10rgb2_cfg_t *cfg );

• c10x10rgb2_default_cfg Click Default Configuration function.

  err_t c10x10rgb2_default_cfg ( c10x10rgb2_t *ctx );

Example key functions :

• c10x10rgb2_write_char This function writes a single ASCII character in a 8x8 font size.

  err_t c10x10rgb2_write_char ( c10x10rgb2_t *ctx, uint8_t data_in );

• c10x10rgb2_write_string This function writes a text string in a 8x8 font size by scrolling characters to the left side.

  err_t c10x10rgb2_write_string ( c10x10rgb2_t *ctx, uint8_t *data_in, uint16_t speed_ms );

• c10x10rgb2_draw_picture This function draws a 10x10px picture on the screen.

  err_t c10x10rgb2_draw_picture ( c10x10rgb2_t *ctx, const uint32_t *image );

Example Description

This example demonstrates the use of the 10x10 RGB 2 Click board by showing a practical example of using the implemented functions.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    c10x10rgb2_cfg_t c10x10rgb2_cfg;  /**< Click config object. */

    /** 
     * 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 " );

    // Click initialization.
    c10x10rgb2_cfg_setup( &c10x10rgb2_cfg );
    C10X10RGB2_MAP_MIKROBUS( c10x10rgb2_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == c10x10rgb2_init( &c10x10rgb2, &c10x10rgb2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( C10X10RGB2_ERROR == c10x10rgb2_default_cfg ( &c10x10rgb2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Displays digits 0-9 first, then writes RGB chars and demonstrates the rotation of characters. After that, scrolls the text, displays the MIKROE logo image, and showcases a rainbow demo. All data is logged on the USB UART where you can track the program flow.

void application_task ( void )

    for ( uint8_t digit = '0'; digit <= '9'; digit++ )
    {
        c10x10rgb2_write_char ( &c10x10rgb2, digit );

    c10x10rgb2_write_string ( &c10x10rgb2, "MIKROE 10x10 RGB 2", 50 );
    Delay_ms ( 1000 );

    log_printf( &logger, " Drawing MIKROE logo\r\n\n" );

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:

• Click.10x10RGB2

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. UART terminal is available in all MikroElektronika compilers.
