如上题，用8脚的STC8G1K08A输出占空比可调的方波。一个10K电位器接在芯片的第1脚作电压取样，调节电位器，在第7脚输出占空比可变的方波信号，频率大约1KHz。1脚电压越高，7脚输出的占空比越大。

//STC8G1K08A （1.9-5.5V阔电压范围芯片） SOP8 封装的8脚芯片 0.75元一个单节18650锂电供电,
//4V时空白的芯片电流为1.7mA,烧录程序后为2.5mA（烧录时选12MHz频率）
//Y0=P3^2; //PWM输出端1%--100%占空比,K=(dat*256+dat1)/500;// 4v Vcc端串联2K到10K电位器上端子，
//下端子接地，中点接P5.4口取样，调节电位器，P3.2脚出1%--100%占空比脉冲

你发个用电位器取样来调节占空比输出方波的程序上来哈，越简单越好。

如果要把电压转换成占空比，NE555比较难实现的。

换个思路，改变电阻就是改变电容的充放电时间

印象中改变5脚电位，也能改变输出占空比，性能肯定不如单片机的。

别人教我的转分享给你吧，发帖时上侧工具条里有一个<>标签，按它就可以出现一个下拉框，将你的程序贴上在发表就是那样了，但值得提醒的是我操作时还是经常乌龙，有时代码贴好后还想输入文字时一回车就都乱了，不知道是我电脑的问题还是网站的问题。

你认为除以10就得当吗？我实际试过除以10不好用，结果试到除以500才能基本对应电位器的调节位置输出相应的占空比。不信你亲自实验一下哈。

用了左对齐的10位转换结果，所以同一般右对齐不同的。
