Software Support

We provide a library for the 7seg Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library covers all the necessary functions for 7SEG click control.

Key functions :

• void c7seg_writeData( uint8_t writeLeft, uint8_t writeRight ) - Generic write data function
• void c7seg_writeDataNumber( uint8_t leftNumber, uint8_t rightNumber ) - Function write left and right number on 7seg display
• void c7seg_writeDataCharacter( char leftChar, char rightChar ) - Function write left and right character on 7seg display

Examples Description

The application is composed of three sections :

• System Initialization - Following pins: CS, RST and PWM are set as output and SPI module is initialized for communcation with 7seg click.
• Application Initialization - Driver initializaion and turning on the display by setting PWM pin to logic 1 and prepare to communcation via SPI.
• Application Task - (code snippet) This example shows functionality of the 7seg click, shows number or character on left and right display.

void applicationTask()
{
    uint8_t counter;

    c7seg__displayOn();
    Delay_1sec();

    c7seg_writeDataCharacter( 'A', 'B' );
    Delay_1sec();

    c7seg_writeData( 0x10, 0x01 );
    Delay_1sec();

    c7seg_writeDataCharacter( '.', '-' );
    Delay_1sec();

    for ( counter = 0; counter < 9; counter ++ )
    {
        c7seg_writeDataNumber( counter, counter+1 );
        Delay_1sec();
    }
    Delay_1sec();

    for ( counter = 65; counter < 90; counter ++ )
    {
        c7seg_writeDataCharacter( counter, counter+1 );
        Delay_1sec();
    }
    Delay_1sec();

    c7seg__displayOff();
    Delay_1sec();
}

The full application code, and ready to use projects can be found on our LibStock page.

• SPI

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.
