Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : SPI type

Software Support

We provide a library for the LcdMono 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 LcdMono Click driver.

Standard key functions :

• Config Object Initialization function.

void lcdmono_cfg_setup ( lcdmono_cfg_t *cfg );

• Initialization function.

LCDMONO_RETVAL lcdmono_init ( lcdmono_t *ctx, lcdmono_cfg_t *cfg );

Example key functions :

• Draw text on the screen

void lcdmono_draw_text ( lcdmono_t *ctx, char *text_buf, lcdmono_text_settings_t *cfg , uint8_t end_mode);

• Display Power State

void lcdmono_display_power ( lcdmono_t *ctx, uint8_t ctrl );

• Reset procedure

void lcdmono_display_reset ( lcdmono_t *ctx );

Examples Description

This application sets text on lcd displey.

The demo application is composed of two sections :

Application Init

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

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

    /** 
     * 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.

    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;
    tx_set.text_color = LCDMONO_COLOR_BLACK;
    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;
    tx_set.text_color = LCDMONO_COLOR_BLACK;
    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;
    tx_set.text_color = LCDMONO_COLOR_BLACK;
    lcdmono_draw_text( &lcdmono, demo_text_128x128px, &tx_set, LCDMONO_REFRESH_DISPLAY_END );

    Delay_ms( 5000 );
    lcdmono_clear( &lcdmono );
}
  

Application Task

Drawing an image to the display every 3 second.

void application_task ( void )
{
    lcdmono_draw_const_frame( &lcdmono, demo_img_mikroe_light );
    Delay_ms( 3000 );
    lcdmono_draw_const_frame( &lcdmono, demo_img_mikroe );
    Delay_ms( 3000 );
    lcdmono_draw_const_frame( &lcdmono, demo_img_logo_light );
    Delay_ms( 3000 );
    lcdmono_draw_const_frame( &lcdmono, demo_img_logo );
    Delay_ms( 3000 );
}

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 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

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.LcdMono

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.
