        At present, there are many dedicated dynamic display interface chips available on the market. However, these chips are generally expensive and not suitable for use in cheap systems. Some dedicated chips (such as MC14489) use hardware decoding, and the amount of information displayed is limited, which is difficult to meet various requirements and affects its application. Here we introduce a low-cost and effective LED dynamic display circuit, which uses software decoding and serial display mode to save a lot of I/O lines. It can not only display numbers, but also most English letters.
