- 本例展示了如何利用外设TIM2来产生四路频率不同的信号。 TIM2时钟设置为36MHz,预分频设置为2,使用输出比较-翻转模式(Output Compare Toggle Mode)。 TIM2计数器时钟可表达为:TIM2 counter clock = TIMxCLK / (Prescaler +1) = 12 MHz 设置TIM2_CCR1寄存器值为32768,则CC1更新频率为TIM2计数器时钟频率除以CCR1寄存器值,为366.2 Hz。因此,TIM2通道1

- 偶数倍分频:偶数倍分频应该是大家都比较熟悉的分频,通过计数器计数是完全可以实现的。如进行N倍偶数分频,那么可以通过由待分频的时钟触发计数器计数,当计数器从0计数到N/2-1时,输出时钟进行翻转,并给计数器一个复位信号,使得下一个时钟从零开始计数。以此循 环下去。这种方法可以实现任意的偶数分频。-Dual frequency many times: even several times frequency should be more familiar with all the sub-fre

- 对于实现占空比为50 的N倍奇数分频,首先进行上升沿触发进行模N计数,计数到某一个值n时输出时钟进行翻转,然后再计数(N-1)/2次,再次进行翻转得到一个占空比非50 奇数n分频时钟。同理,同时进行下降沿触发的模N计数,等计数到n时,输出时钟进行翻转,同样再计数(N-1)/2次,输出时钟再次翻转生成占空比非50 的奇数n分频时钟。两个占空比非50 的n分频时钟进行相或运算,即得到占空比为50 的奇数N分频时钟。verilog HDL实现-For achieving a 50 duty cyc
