Library Description

The library covers all the necessary functions to control 7-SEG RGB click board.

Key functions:

  • void c7segrgb_gpioDriverInit(T_PS2_P gpioObj) - Function initializes GPIO driver for the desired MIKROBUS1.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes GPIO, LOG structures.
  • Application Initialization -  Initialization driver enables - GPIO.
  • Application Task - (code snippet) This is an example which demonstrates the use of 7-SEG RGB Click board. This simple example shows all ten numbers in different colors on 7-SEG RGB click.
void applicationTask() 
{
    uint8_t cnt_i;
    uint8_t cnt_j;
    
    for ( cnt_i = 0; cnt_i < 10; cnt_i++ )
    {
        for ( cnt_j = 10; cnt_j > 0; cnt_j-- )
        {
            c7segrgb_setSevenSegment( _CHARACTER_TABLE[ cnt_i ], 4 * cnt_i, 4 * cnt_j, cnt_i * cnt_j );
            Delay_100ms();
        }
    }

    c7segrgb_setSevenSegment( _C7SEGRGB_POINT, 10, 10, 10 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_ZERO, 40, 40, 40 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_ONE, 40, 0, 0 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_TWO, 0, 40, 0 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_THREE, 0, 0, 40 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_FOUR, 40, 0, 40 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_FIVE, 0, 40, 40 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_SIX, 40, 40, 0 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_SEVEN, 20, 30, 40 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_EIGHT, 40, 15, 31 );
    Delay_1sec();

    c7segrgb_setSevenSegment( _C7SEGRGB_NINE, 20, 10, 30 );
    Delay_1sec();

    RGB_CONTROL_BIT = 0;
}        

Additional Functions :

  • void c7segrgb_logicOne() - Generic logic one function.
  • void c7segrgb_logicZero() - Generic logic zero function.
  • void c7segrgb_setColor( uint8_t _green, uint8_t _red, uint8_t _blue ) - Set the color of the  LSB segment of the display function.
  • void c7segrgb_setSevenSegment( uint8_t  _character, uint8_t _greenBrightness, uint8_t _redBrightness, uint8_t _blueBrightness ) - Set whole character and color function.

Other mikroE Libraries used in the example:

  • One_Wire
  • UART​
  • Conversion

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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
