Applications of Frequency Counter The frequency counter finds application in various instruments, that are dependant on the frequency. The frequency, 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 circ...
but it appears to be that when the specified edge occurs at the input pin, exactly one pulse from the 125 MHz system clock is fed through to the counter. Thus, this configuration is effectively a pulse counter, with the limitation that input edges are "synchronous" at 125 MHz (meaning in...
[FrankBuss] has approached withan Arduino-based counterthat offloads the timing question to a host PC, and thus claims atomic accuracy due to its clock being tied to a master source via NTP. The Rust code PC-side provides continuous readings whose accuracy increases the longer it is left ...
The working of the frequency counter can be explained from the above circuit diagram. The pulse generated from the square wave generator (Arduino UNO) is given to the pin 3.5 (port 3) of 8051 microcontrollers. Pin 3.5 of 8051 acts as timer 1 and configured as a counter. TCON TR1 bit ca...
High Resolution Frequency Counter: This instructable shows a reciprocal frequency counter capable of measuring frequencies fast and with reasonable precision. It is made with standard components and can be made in a weekend (it took me a bit longer :-) )
The most important part for the accuracy of the frequency counter is the time base setting circuit – crystal resonator X1 and capacitors C4 and C5. C4 and C5 values can be between 33pF and 62pF and the crystal frequency can be fine tuned with them. ...

On the Arduino UNO and YourDuino RoboRED etc., pins 3,5,6, 9, 10, 11 can be configured for PWM output. The 8-bit PWM value that you set when you call the analogWrite function: analogWrite(myPWMpin, 128); Outputs a square wave is compared against the value in an 8-bit counter....
I have a frequency counter that's very accurate. Let me check with that. Of course, I don't know how accurate the Arduino clock is to start with ;-( Sorry, something went wrong. khoih-prog added a commit that referenced this issue Oct 12, 2022 v1.2.0 to fix accuracy bug … ...
This project is nice and small frequency counter that reads frequency from 1 Hz to 50 MHz that I have modified from original designed by Weeder Technologies . I have designed new PCB to fit with 16X1 LCD and change source code for compatible with new sma
