Application Init

Driver initialization - Starting LCD Mono display. Print text to the display by changing font size ...

void application_init ( void )
{
    lcdmono_cfg_t cfg;
    lcdmono_text_settings_t tx_set;
    lcdmono_font_t font_cfg;

    //  Click initialization.
    lcdmono_cfg_setup( &cfg );
    LCDMONO_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    lcdmono_init( &lcdmono, &cfg );

    lcdmono_display_reset( &lcdmono );
    lcdmono_clear( &lcdmono );

    // Background color for all text
    tx_set.bg_color = LCDMONO_COLOR_WHITE;
    // Display text
    font_cfg.this_font = lcdmono_font_tahoma_16;
    lcdmono_set_font( &lcdmono, &font_cfg );

    tx_set.len = 3;
    tx_set.start_cord_x = 25;
    tx_set.start_cord_y = 15;
    lcdmono_draw_text( &lcdmono, demo_text_lcd, &tx_set, LCDMONO_REFRESH_TEXT_BUFFER | 
                                                         LCDMONO_CHECK_NEW_TEXT );

    font_cfg.this_font = lcdmono_font_tahoma_8;
    lcdmono_set_font( &lcdmono, &font_cfg );

    tx_set.len = 4;
    tx_set.start_cord_x = 60;
    tx_set.start_cord_y = 50;
    lcdmono_draw_text( &lcdmono, demo_text_mono, &tx_set, LCDMONO_CHECK_NEW_TEXT );

    tx_set.len = 9;
    tx_set.start_cord_x = 10;
    tx_set.start_cord_y = 80;
    lcdmono_draw_text( &lcdmono, demo_text_128x128px, &tx_set, LCDMONO_REFRESH_DISPLAY_END );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    lcdmono_clear( &lcdmono );
}

Application Task

Drawing an image to the display every 3 second.

void application_task ( void )
{
    lcdmono_draw_frame( &lcdmono, demo_img_mikroe_light );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    lcdmono_draw_frame( &lcdmono, demo_img_mikroe );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    lcdmono_draw_frame( &lcdmono, demo_img_logo_light );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    lcdmono_draw_frame( &lcdmono, demo_img_logo );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

• Create Image: Save the image in resolution of 128x128 px with the extension (monochrome bmp) ... Upload the image to Image2Lcd program Set parameters to: 1. Output file type : C array 2. Scan Mode : Horisontal scan 3. Bits Pixel : monochrome 4. Max width and height : 128x128 5. Check only MSB first 6. Check Reverse color and adjust Normal type The image to be generated should contain about 2048 bytes ... Insert the image into the file lcdmono_image.h

• Create Font: Close existing project, open a new VTFT project Add label and adjust text font Generate source code Copy the font from resource.c file to this project in file lcdmono_font.h

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
