however, has to be a steady one, to get accurate results. These are used to measure frequency in the transmitter carrier, the oscillator in the circuit, analog, and digital signals, etc. In short, you can use the frequency counter whenever there is a requirement ...
ArduinoPWM频率设置 Then I chagne the PWM frequency by the following code.// *** var = 0x07; //variable with value binary 00000111 TCCR2B &= ~var; //clear TCCR2B bits 0, 1, and 2 var = 1; //variable with value binary 00000001 TCCR2B |= var; //set TCCR2B to binary ...

Arduino程序的总体结构Arduino程序基本结构由setup和loop两个函数组成:Arduino控制器通电或复位后,即会开始执行setup函数中的程序,该部分 只会执行一次。通常我们会在setup函数中完成Arduino的初始化设置

The input signal is 1013 to 1014 Hz measured on the PIC frequency counter. It drifted up a little as the source is not high stability. The most consistent results are for the assembler version (pulsein) with interrupts off. When interrupts are on pulseIn results vary a lot. Interestingly, ...
