数码管驱动
|
||
驱动使用
|
||
引脚连接： 数据线 DI: 时钟线 CLK: 片选线 CS:
|
||
1、调用begin(brightness)初始化，参数brightness为亮度值：0-15
|
||
2、调用displayDigital(int val)可显示一个整数。
|
||
调用displayDigital(float val)可显示浮点数（带小数点）。
|
||
调用displayDigital(long val)可显示长整型数。
|
||
调用displayDigital(int val, int digital)。可显示单个数位
|
||
3、调用clearDisplay()可清除数码管。
