信号发生器的频率测量,主要是运用单片机的外部中断计数器对方波信号的进行脉冲计数实现。
内部定时器T0设定外部计数器的计数时间t,在t时间到达是从外部计数器读出计数的脉冲个数n,
从可以根据t和n计算出信号的频率。
-Frequency measurement signal generator, mainly using MCU external interrupt counter counts each pulse wave signal is achieved.
Internal timer T0 is set outside the counter time t, at time t arrive is read out from the external counter counts the number of pulses n,
T, and n can be calculated from the frequency of the signal.
