利用PID增量式算法调节PWM信号的输出波形，使其更加稳定(Using PID incremental algorithm to adjust the output of the PWM signal waveform, make it more stable)

判断K线走势的顶底用MCAD RSI背离效果最佳，而大部分人无法准备把我顶顶背离的用法，这个指标直接标记处背离位置。效果很好。很值钱的指标。(The top and bottom to judge the trend of the K line MCAD RSI departure from the effect, and most people can not prepare my the Dingding departure from the use of this indicator directly mark departure from the position. Good results. Very valuable indicators.)
