This library turns your Arduino into a seven segment display controller. Use it to easily display numbers on your seven segment display without any additional controllers. Supports: 1 to 8 digit displays common cathode and common anode displays ...
1. sevseg.begin(hardwareConfig, numDigits, digitPins, segmentPins)函数: hardwareConfig:使用的是共阳极数码管还是共阴极数码管。 COMMON_CATHODE:共阴极。 COMMON_ANODE:共阳极。 numDigits:数码管位数,我们这里使用的是一位数码管,故其值设置为1。
单片机的数字I/O端口引脚可直接驱动数码管显示,Arduino的数字I/O引脚只能单个位控制,使驱动数码管显示器显示数字的流程图比较复杂。应用系统提供的“Grove 4-Digit Display Module”模块,使应用系统的硬件电路设计更加简单,通过模块提供的图框绘制流程图更加方便。
