Microcontroller Pulse Duration Measurement

Introduction to pulse In

The pulse In function is a powerful tool for measuring the duration of a pulse (high or low) from one of the pins on a microcontroller. This function is particularly useful in applications such as distance measurement using ultrasonic sensors, where the duration of the pulse can be translated into distance.

Key Features:

• Pin Selection: You can specify which pin to use (e.g., P0, P1, P2, etc.).
• Pulse Value: The function allows you to measure either a high or low pulse.
• Maximum Duration: You can set a maximum duration to wait for the pulse, ensuring that your program can handle cases where no pulse is received.

Use Cases:

• Distance Measurement: Use with ultrasonic sensors to measure distances by sending and receiving pulses.
• Signal Processing: Capture and analyze pulse signals for various applications in electronics and robotics.
