Tick Tock Shield Assistance Please

[Jacket_Chen]

hey,you can have a test:

#include “Wire.h”
#include <TimerOne.h>
#include <EEPROM.h>
#include “TM1636.h”
#include “TickShield.h”
/Declare a TickShield Class object/
TickShield tickshield;

void setup()
{
tickshield.init();
}
void loop()
{
tm16363.display(0x00,0x00); //A1
//tm16363.display(0x01,0x00); //A2
//tm16363.display(0x02,0x00); //A3
//tm16363.display(0x03,0x00); //A4
}

You can test A1 port first,and then modify you program

//tm16363.display(0x00,0x00); //A1
tm16363.display(0x01,0x00); //A2
//tm16363.display(0x02,0x00); //A3
//tm16363.display(0x03,0x00); //A4

After all ports you have been tested,whether your result is the same to me?

The voltage which port you are testing is about 1.37v-1.5v,and the others are about 1.7-1.8v.So you can see the voltage which the port you are using is different from others clearly.

If you have time to do this test,please show us your result.Thanks.
