Click library

Software Support

We provide a library for the MatrixRGB 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 MatrixRGB Click driver.

Standard key functions :

Example key functions :

Examples Description

This application is used for powering 16x32 RGB LED matrices.

The demo application is composed of two sections :

Application Init

Initializes driver, reset device and initializes firmware depend on pattern used alongside with fonts

void application_init ( void )
{
log_cfg_t log_cfg;
matrixrgb_font_t font_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.
MATRIXRGB_MAP_MIKROBUS( cfg, MIKROBUS_1 );
matrixrgb_init( &matrixrgb, &cfg );
matrixrgb_device_reset( &matrixrgb );
matrixrgb_set_power( &matrixrgb, 1 );
Delay_ms( 1000 );
font_cfg.p_font = Arial9x9;
font_cfg.color = 0xFFFF;
matrixrgb_set_font ( &matrixrgb, &font_cfg );
matrixrgb_fill_screen( &matrixrgb, 0xFFFF );
Delay_ms( 1000 );
}

Application Task

Test of panel brightnes, draws red cross on the panel using pixel write function, writes text on panel using write text function and finaly displays image on the panel.

{
uint16_t test;
// Brightness Test
for ( test = 5; test < 50; test++ )
{
matrixrgb_set_brightness( &matrixrgb, test );
Delay_ms( 50 );
}
for ( test = 50; test > 5; test-- )
{
matrixrgb_set_brightness( &matrixrgb, test );
Delay_ms( 50 );
}
// Pixel Write Test
matrixrgb_fill_screen( &matrixrgb, 0x0000 );
for ( test = 0; test < 32; test++ )
{
matrixrgb_write_pixel( &matrixrgb, test, test, 0xF100 );
Delay_ms( 100 );
}
for ( test = 32; test > 0; test-- )
{
matrixrgb_write_pixel( &matrixrgb, 32 - test, test, 0xF100 );
Delay_ms( 100 );
}
//Text Write Test
matrixrgb_fill_screen( &matrixrgb, 0x0000 );
matrixrgb_write_text( &matrixrgb, "RGB", 6, 5 );
matrixrgb_write_text( &matrixrgb, "Demo", 4, 20 );
Delay_ms( 2000 );
// Image Test
matrixrgb_draw_image( &matrixrgb, &mikroe_logo_32x32_bmp[ 0 ] );
Delay_ms( 1000 );
}

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.
