摘要
利用Luminary Micro Stellaris系列LM3S301微控制器的同步串行接口(SSI)技术,LED数码管显示器段选码与位选码全部由74HC595串行输入移位寄存器控制,设计了一种只需3根信号线的多位数码管显示驱动电路,并给出了部分程序源代码。
Using the technology of SSI （synchronous serial interface）of the microcontroller LM3S301, which is a member of luminary micro stellaris family,light-emitting-diode digital display＇s segmentselected-code and channel-selected-code are all controlled by serial-in shift registers-74HC595.A type of circuit driving multi-channel digital display is designed that need only three signal wires, and some of the source code are given in this article.
