PSOC 5lp BPM中断问题

嘿，伙计们，
我正在一个项目中，PSoC 5LP将在一些音乐中产生精确的中断。我挣扎着产生一个一致的中断不会随着时间流逝…中断处理程序内部将有一些代码来控制一些电机。
到目前为止，我使用一个连接到12MHz锁相环时钟的计时器来产生溢出的中断。定时器被设置为连续的UDB实现（固定没有足够大的分辨率来处理较慢的BPMS）。
我也在努力改变计时器的动态周期…我已经尝试过：
周期＝（60×CcLogiBPMY-FRIQ）/BPM//CCHOLYB-BPMY-FRQ是定时器时钟（12000000）和BPM周期性的频率。
timeRyBPMa写作周期（周期）；
TimeR.BPMI Wrand CeCuter（0）；
任何关于如何解决这些问题的想法，将不胜感激！！
节日快乐

  Hey guys,
I am working on a project where the PSOC 5LP will generate an accurate interrupt in beat with some music. I am struggling with generating a consistent interrupt that will not stray with time... Inside the interrupt handler will be some code to control some motors

So far I am using a timer connected to a 12MHz PLL clock to generate the interrupt on overflow. The timer is set on continuous with a UDB implementation (fixed does not have resolution big enough to handle slower BPMs)

I am also struggling with altering the period of the timer dynamically... I have tried this:

period = (60*CLOCK_BPM_FREQ)/BPM //  CLOCK_BPM_FREQ is the frequency of the timers clock (12000000) and BPM periodically.

timer_BPM_WritePeriod(period);
timer_BPM_WriteCounter(0);


Any ideas on how to solve these problems would be much appreciated!!

Happy Holidays
