Guangzhou Tower

Overview

Adding a totem pole increases the driving current.
Adding Bluetooth allows for programmable remote control.
A 16×16 LED matrix, each LED can be controlled individually and
can display letters and numbers. More gorgeous ways to play are waiting to be unlocked.
The problem I encountered is that the main control chip has 44 pins, and only 40 pins are defined in the header file. There are still four unavailable pins.
The video shooting effect is not very good. In addition, I am a bad welder, which makes the Canton Tower look 100 million points ugly.
