Library Usage

#include "SMA420564.h"

SMA420564 Display;

void setup(void) 
{
    /* ... code ... */
}

void loop(void)
{
    Display.write(1234);
    
    // Decimal values:
    //      Display.write(  9999, DEC);
    
    // Binary:
    //      Display.write(0b1010, BIN);
    
    // Hexadecimal values:
    //      Display.write(0xBEEF, HEX);
    //      Display.write(0xCAFE, HEX);

    // Enable display point, index ranges from 0 to 3
    //      Display.point(2);

    // Set display points in parrallel
    //      Display.set_points(0b0101);


    // Write raw data to ports:
    // you can refer to the static array `digits` which holds the raw bytes for the 16 symbols
    //      Display.write(0xFFFFFFFF, DEC, RAW);
