Library Description 
The library covers all the necessary functions for UT-S 7SEG R click control.

Key functions 
uts7segr_writeData - Generic write function
uts7segr_writeNumDec - Writes decimal number
uts7segr_writeNumHex - Writes hexadecimal number

Examples Description
The demo application is composed of three sections:

• System Initialization - Initialize GPIO pins and SPI module for communication with UT 7SEG click.
• Application Initialization - Driver Initialization and turning on the lights by setting PWM pin to logical 1.
• Application Task - Contains four sequences:
  • The first sequence shows how to use generic write functions by providing minus and custom. 
  • The second sequence is a demonstration of the counter using the function for decimal numbers.
  • The third sequence is a demonstration of the counter using the function for hexadecimal numbers.
  • The fourth sequence is a demonstration of the counter using a function with dot option.

NOTE: Brightness can be adjusted using the MCUs PWM module. In that case, GPIO setup for PWM pin is not necessary.

void applicationTask()
{
    uts7segr_writeData( _UTS7SEGR_MINUS, 0xFF );
    
    counter = 0;
    while (counter < 3)
    {
        uts7segr_lightCtl( 0 );
        Delay_ms( 200 );
        uts7segr_lightCtl( 1 );
        Delay_ms( 300 );
        counter++;
    }
    
    counter = 0;
    while (counter < 100)
    {
        uts7segr_writeNumDec( counter );
        Delay_ms(100);
        counter++;
    }
    
    counter = 0;
    while (counter < 0xFF)
    {
        uts7segr_writeNumHex( counter );
        Delay_ms(100);
        counter++;
    }
    
    counter = 0;
    while (counter < 100)
    {
        uts7segr_writeNumDot( counter, _UTS7SEGR_DOT_L );
        Delay_ms(100);
        counter++;
    }
}

Additional notes and information
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.
