digitLedDisplay.printDigit(1234, 4);

Quickstart

#include <DigitLedDisplay.h>

// initialize with pin numbers for data, cs, and clock
DigitLedDisplay ld = DigitLedDisplay(7, 6, 5);

void setup() {
  ld.setBright(15); // range is 0-15
  ld.setDigitLimit(8);
}

long i = 12345678;

void loop() {
  ld.printDigit(i++);
  delay(10);
}
