Guzunty Pi gz led driver testing notes

Now I am reading my old blog post on Gzunty LED driver.

I remember that I did not have the LED displaying what is expected.  Last time I only used a 3 digit LED and I got confused of the digital and segment signals.

This time I have ordered a couple of 4 digit LEDs.  I just checked that these LED toys are on their way from ShenZhen to Hong Kong.
