资 源 简 介
本实验完成发光二极管的循环点亮实验，由于输入晶振为20M，分频得到count1信号，故每间隔约1S彩灯循环移位一次。
也可以外接32768hz的晶振经4060分频后的1HZclk输入，自己可以尝试改变实验，加以练习。
现象：可以看到流水灯-In this experiment completed the cycle of light-emitting diode light experiments, as a result of the importation of crystal for the 20M, sub-frequency signal received count1, so each interval of about 1S Lantern a cyclic shift. Can also be the external 32768Hz crystal oscillator frequency by 4060 after 1HZclk input, they can try to change the experiment, to practice. Phenomenon: we can see water lights
