Library Description

The library initializes and defines the SPI bus driver and drivers that offer a choice for writing data. The library includes function for displays image or frame, draw text on the screen and function for settings font.

Key functions:

• void lcdmono_draw_const_frame ( const uint8_t *frame_data ) - Displays draw const frame
• void lcdmono_draw_text ( char *text_buf, lcdmono_text_settings_t *cfg , uint8_t end_mode) - Draw text on the screen
• void lcdmono_set_font ( const uint8_t *font ) - Set font
• void lcdmono_display_reset ( void ) - Reset procedure

Examples description

The application is composed of three sections :

• System Initialization - Initialization SPI modules and all necessary GPIO pins
• Application Initialization - Driver initialization - Starting LCD Mono display. Print text to the display by changing font size
• Application Task - Drawing an image to the display every 3 second.

void applicationTask (  )
{
    lcdmono_draw_const_frame( &demo_img_mikroe_light[ 0 ] );
    Delay_ms( 3000 );
    lcdmono_draw_const_frame( &demo_img_mikroe[ 0 ] );
    Delay_ms( 3000 );
    lcdmono_draw_const_frame( &demo_img_logo_light[ 0 ] );
    Delay_ms( 3000 );
    lcdmono_draw_const_frame( &demo_img_logo[ 0 ] );
    Delay_ms( 3000 );
}

Create Image: Save the image in resolution of 128x128 px with the extension (monochrome bmp) ... Upload the image to Image2Lcd program Set parameters to:

• Output file type : C array
• Scan Mode : Horisontal scan
• Bits Pixel : monochrome
• Max width and height : 128x128
• Check only MSB first
• Check Reverse color and adjust Normal type

The image to be generated should contain about 2048 bytes ... Insert the image into the file Click_LCD_Mono_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 Click_LCD_Mono_font.h

Other mikroE Libraries used in the example:

• SPI
• UART

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.
