Web1. Principle. I have always thought that truly understanding one thing and knowing one thing are two realms. If you want to reach the top of the world, you must understand the truth and that is necessary. Webvoid ConfigPWM(unsigned int fr, unsigned char dc) { unsigned int high, low; unsigned long tmp; tmp = (11059200/12) / fr; //计算一个周期所需的计数值 high = (tmp*dc) / 100; //计算高电平所需的计数值 low = tmp - high; //计算低电平所需的计数值
Web加入说我们要定时2ms,也就是0.002秒,设需要计时x个机器周期,那么 x * (12/11059200) = 0.002,那么x = 0.002 *(11059200 / 12),而这个x就是我们程序中的tmp了,这个tmp是我们需要计时的个数,那我们的初值怎么计算呢?很简单,只要用 65536-tmp 就好了呀,来看一下代码: Webunsigned long tmp; //临时变量 tmp = 11059200 / 12; //定时器计数频率 tmp = (tmp * ms) / 1000; //计算所需的计数值 tmp = 65536 - tmp; //计算定时器重载值 tmp = tmp + 33; //补偿中断响应延时造成的误差 T0RH = ( unsigned char ) (tmp>> 8 ); //定时器重载值拆分为高低字节 T0RL = ( unsigned char )tmp; TMOD &= 0xF0; //清零 T0 的控制位 TMOD = 0x01; //配置 T0 …
