Ahhah, not the best representation, but we tried to do our best 🙂

Second, we want to add additional information to our output, like the number of outputs / digits in our payload, it’s duration as well as the whole payload duration.

Also, the crucial one, we have to calculate the last digit correctly. In our previous code the last digit will be always 0 because we are comparing 1000 “zeros” with some “1s”. In the updated code we will get the average number of elements in items and decrease the number of “1s” to get the number of “0s”. And only after that compare them and get the correct last digit in the payload.  

The final code is the next:

#Add number of outputs, duration of each element, payload duration and correct last digit

 

import RPi.GPIO as GPIO

import time

 

# Set up GPIO using BCM numbering

GPIO.setmode(GPIO.BCM)

 

# Define the pin numbers

input_pin = 26

 

# Set up the pin as input

GPIO.setup(input_pin, GPIO.IN)

 

data = “”  # Variable to store the collected data

start_collecting = False  # Flag to indicate when to start collecting data

zero_count = 0  # Counter for consecutive zeros

output_count = 0  # Counter for number of outputs

duration = 0 # Define the duration time

average10 = 0 # Counter of average digits

sum10 = 0 # Counter of each number of digits

 

while True:

    # Read the value of the input pin

    pin_value = GPIO.input(input_pin)

 

    # Check if the pin value is 1 and start collecting data

    if pin_value == 1 and not start_collecting:

        start_collecting = True

       

        # Record the start time of data collection

        start_time = time.time()

 

    # If we’re collecting data, append the pin value to the data string

    if start_collecting:

        data += str(pin_value)

 

        # Increment zero_count if pin value is 0

        if pin_value == 0:

            zero_count += 1

        else:

            zero_count = 0  # Reset zero_count if pin value is 1

 

    # Check if we’ve started collecting data and encountered a ‘1’ after ‘0’s

    if start_collecting and pin_value == 1 and ‘0’ in data:

        # Calculate the number of ‘1’s and ‘0’s

        ones = data.count(‘1’)

        zeros = data.count(‘0’)

        sum10 += ones + zeros

 

        # Determine the output based on the count of ‘1’s and ‘0’s

        if ones > zeros:

            print(‘1’, end=”)

            output_count += 1

            average10 = sum10 / output_count

        elif zeros > ones:

            if zeros > 1000:

                output_count += 1

                average10 = sum10 / output_count

                # Calculating last element

                last_zeros = average10 – ones

                if last_zeros > ones:

                    print(‘0’, end=”)

                else:

                    print(‘1’, end=”)

                print(” pause || # of outputs:”, output_count, “|| Duration of each element:”, round(duration, 5), “sec || Payload duration:”, round(output_count * round(duration, 5),4), “sec || Average digits:”, round(average10,1))

                output_count = 0

                average10 = 0

                sum10 = 0

            else:

                print(‘0’, end=”)

                output_count += 1

                average10 = sum10 / output_count

 

        # Reset data and start_collecting for the next sequence

        data = “”

        start_collecting = False

        # Record the end time of data collection

        end_time = time.time()

        # Calculate the duration of data collection

        duration = end_time – start_time

        zero_count = 0
