The tiny7 does also work with the Arduino IDE and the ESP8266. And five digits do work well. And a supply voltage of only 3.3V is also working.

The library for writing chars is still very experimental - as you can see by the code used:

#include <tiny7.h>
#define S_SDO 12
#define S_CLK 14
#define S_LTH 16
tiny7 myTiny7;

void setup() 
{
  myTiny7.begin(0, S_SDO, S_CLK, S_LTH);	
  myTiny7.show(7,0);    // ptint 7
  myTiny7.show(20,0);   // print Y
  myTiny7.show(16,0);   // print n
  myTiny7.show(19,0);   // print i
  myTiny7.show(18,0);   // peint t
  delay(1000);
}

I will try to add a better way to show strings or larger numbers soon. I am thinking of something like: myTiny7.print("string").
