Click library

  • Author : MikroE Team
  • Date : Jul 2020.
  • Type : SPI type

Software Support

We provide a library for the DotMatrixR 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 DotMatrixR Click driver.

Standard key functions :

  • Config Object Initialization function.

    void dotmatrixr_cfg_setup ( dotmatrixr_cfg_t *cfg );

  • Initialization function.

    DOTMATRIXR_RETVAL dotmatrixr_init ( dotmatrixr_t ctx, dotmatrixr_cfg_t cfg );

Example key functions :

  • Sets BL pin to high or low state

    void dotmatrixr_set_bl_pin_state ( dotmatrixr_t *ctx, uint8_t state );

  • Restart device

    void dotmatrixr_restart ( dotmatrixr_t *ctx );

  • Sets display to written value

    void dotmatrixr_write_ascii ( dotmatrixr_t ctx, char ascii_data );

Examples Description

This demo application show data on display.

The demo application is composed of two sections :

Application Init

Configuration device


void application_init ( void )
{
    log_cfg_t log_cfg;
    dotmatrixr_cfg_t 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.

    dotmatrixr_cfg_setup( &cfg );
    DOTMATRIXR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    dotmatrixr_init( &dotmatrixr, &cfg );

    Delay_ms ( 100 );
    dotmatrixr_restart( &dotmatrixr );
    Delay_ms ( 500 );

    dotmatrixr_set_bl_pin_state( &dotmatrixr, 0 );
    dotmatrixr_set_rs_pin_state( &dotmatrixr, 0 );

    dotmatrixr_ctrl_1( &dotmatrixr, DOTMATRIXR_CTRL_BYTE_1_OSC_PRESCALER_1 |
                       DOTMATRIXR_CTRL_BYTE_1_DOUT_DIN );
    dotmatrixr_ctrl_0( &dotmatrixr, DOTMATRIXR_CTRL_BYTE_0_BRIGHTNESS_30 |
                       DOTMATRIXR_CTRL_BYTE_0_PIXEL_PEAK_CURRENT_9p3mA |
                       DOTMATRIXR_CTRL_BYTE_0_MODE_NORMAL );
}

Application Task

Display shows 3 different data in span of 1 second


void application_task ( void )
{
    dotmatrixr_write_ascii( &dotmatrixr, &demo_t1[ 0 ] );
    Delay_ms ( 1000 );
    dotmatrixr_write_ascii( &dotmatrixr, &demo_t2[ 0 ] );
    Delay_ms ( 1000 );
    dotmatrixr_write_ascii( &dotmatrixr, &demo_t3[ 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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.DotMatrixR

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.
