pwm输出，能够实现随意改变占空比的pwm输出(PWM output, can achieve arbitrary change of duty cycle PWM output)

说明：  实现倒立摆,2013年电赛题目，代码简单耐看(Implementing inverted pendulum)

cj60lib示例代码，包含例子的工程，虽然简单却实用。(example of cj60lib)

字模软件取模代码之后，8*8点阵按照代码显示出相对应的字符与简单汉。(After modulus matrix software code, 8* 8 dot matrix display in accordance with a code corresponding to the character and simple Chinese.)
