Digital tube experiments This study is through the 74 hc595 are needed for digital tube display control chip. Before starting the experiment needs to connect J4, J10 jumper and JP3 jump quad. Is there a public IO mouth with DS1302 and 74 hc595 are needed, so to operation of 74 hc595 are needed to close the DS1302 chip first. The focus of this experiment: 1, learn to series with 74 hc595 are needed and cascade and chip applications 2, understand the principle of digital tube dynamic scanning drive The application of 3, _nop_ () function
