8*8RGB dot matrix

Overview

This project is an 8*8RGB dot matrix screen, controlled by four 74HC595 and ULN2803. The working voltage is 3.3v or 5v optional. The power supply method can be DC line power supply or the power interface of the cascade interface. There is The silk screen information of the interface can be controlled with only a few IO ports. It has a cascade interface and the printed boards will not be wasted. It is a show-off and a confession artifact. I wrote a few test programs using 32 (I just learned it, so I can’t write it well. Strange)

About GPRS module
I use Zhou Ligong's ZWG-13A module, and the instruction set is AT. I can dial in Windows. But in Linux, there is no response when debugging through minicom, and wvdialconf can't detect the baud rate.
