Simple ESP32 Hardware Timer Interrupt with tests using frequency counter and oscilloscope - Egoruch/ESP32-TIM-INT-ARDUINO ...

The frequency counter code is basically driven by the 1PPS interrupt. When a 1PPS interrupt occurs, the interrupt service routine responds by locking in the 32-bit counter, clearing the counter, and ...

Features Interrupt-based Counting: The counter employs interrupts to detect and count digital events, ensuring precise and timely counting without blocking the Arduino's main loop. High Accuracy: By ...

Arduino Frequency Counter Code Explanation: Code for this frequency measurement using arduino is quite simple and easily understandable. Here we are explaining the pulseIn function which is mainly ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum fr… ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

French developer is looking for support amongst the Arduino community for his crowd-funding project – an Arduino compatible high precision frequency counter. Thierry Guennou, writes: “The concept of ...
