Not able count Pulses Generated by PLC

Question

I am using the below code to capture the pulses and count pulses for a specified interval but the output not as what i expected. For every pulse it is giving uncertain value.

The pulse i want to count is from a motor that will generate one pulse per rotation.

I am using Proximity Sensor for counting rotations.

CODE

import time

import pigpio

WIND_GPIO=4

pi = pigpio.pi()

pi.set_mode(WIND_GPIO, pigpio.INPUT)
pi.set_pull_up_down(WIND_GPIO, pigpio.PUD_UP)

wind_cb = pi.callback(WIND_GPIO, pigpio.FALLING_EDGE)

old_count = 0

while True:

   time.sleep(5)

   count = wind_cb.tally()
   print("counted {} pulses".format(count - old_count))
   old_count = count

pigpio.stop()

I found this code on https://www.raspberrypi.org/forums/viewtopic.php?p=507103

I want to count pulses for two conditions:

(i) One for all rotations from the beginning to End of program

(ii) Count Pulse based on other Pin Status Condition for example start counting if PIN A is HIGH.

How to achieve above mentioned condition using PIGPIO module

Answer 1

You are using a long deprecated version of the pigpio Python module. Where did you find it?

I suggest you download the latest version of pigpio from the Raspbian repositories.

Try this code.

!/usr/bin/env python

import time

import pigpio # http://abyz.me.uk/rpi/pigpio/python.html

pi = pigpio.pi()
if not pi.connected:
   exit(0)

cb = pi.callback(4)

while True:
   print(cb.tally())
   cb.reset_tally()
   time.sleep(10)
