    ways.

+   Additionally tested on ATtiny84 using 8MHz internal clock. To
+   enable this functionality, you must alter the USI_TWI_Master.h
+   file in the TinyWireM library to run at 8MHz. Search for the 
+   line near the top that reads:
+   #define SYS_CLK   1000.0  // [kHz]	Default for ATtiny2313
+   and change the 1000 to 8000. 
+   
+   Also tested with 10k ohm pull-up resistors on SDA and SCL lines.

   This demo also uses a regular LED attached to 
   ATtiny84 physical pin 2 (Arduino pin 10) to show 
   that the sketch is running. 

    for (int i = 0; i < 5; i++) {
     if (i == 2) i++;  // This is needed to skip over position 2
     sevenseg.writeDigitRaw(i,128); // light the decimal at position i
     sevenseg.writeDisplay();
     delay(100);
     sevenseg.writeDigitRaw(i,0); // clear the decimal at position i
     sevenseg.writeDisplay();
    }
  }
  

//  sevenseg.writeDigitRaw(0,128); // 128 = "." decimal
//  sevenseg.writeDigitRaw(0,0); // blank
//  sevenseg.writeDigitRaw(2,255); // 255 = ":"  colon, always position 2
//  ****Always follow a writeDigitRaw command with the
//  writeDisplay(); command to push the data to the
//  display.*****
//  sevenseg.writeDisplay(); // push data to display

  // Example using writeDigitRaw to write numbers or characters
  // to specific digits on the display. This spells 'run'.
  sevenseg.writeDigitRaw(0,80); // specify position and code, 80 = 'r'
  sevenseg.writeDigitRaw(1,28); // specify position and code, 28 = 'u'
  sevenseg.writeDigitRaw(3,84); // specify position and code, 84 = 'n'
  sevenseg.writeDisplay(); // push data to display
  delay(1000);
