Impulszähler

[Guest ben_bienne]

Hallo,

 

Ich habe ein Master Brick 2.0 und ein IO4 Bricklet. Damit möchte ich Impuls zählen. Ich habe angefangen ein script in Python zu schreiben. Bis jetzt kann ich damit nicht viel machen. Mein Proble ist folgendes

Wie kann ich mit einer loop solche Impuls zählen. Ich schaffe das nichts.

 

Hat jemanden so was schon probiert.

Moin.

 

Meinst du sowas in die Richtung?

 

#!/usr/bin/python3
# -*- coding: utf-8 -*-  

HOST = "127.0.0.1" # Change to your IP
PORT = 4223
UID = "uiD" # Change to your UID

import time

from tinkerforge.ip_connection import IPConnection
from tinkerforge.bricklet_industrial_digital_in_4 import IndustrialDigitalIn4

if __name__ == "__main__":
    ipcon = IPConnection() # Create IP connection
    idi4 = IndustrialDigitalIn4(UID, ipcon) # Create device object

    ipcon.connect(HOST, PORT) # Connect to brickd
    # Don't use device before ipcon is connected
    
    try:
        idi4.set_edge_count_config(1, IndustrialDigitalIn4.EDGE_TYPE_RISING, 1)
        ii = True
        while True:
            print('Edge count: {0}'.format(idi4.get_edge_count(0, ii)))
            time.sleep(0.5)
            ii = False
            
    finally:
        ipcon.disconnect()

Besten Dank für die Hilfe und Entschuldingung für die spätere Antwort.

 

Ich habe mein Zähler mit eine IO4 und 7 segment display gemacht.

 

 

#!/usr/bin/env python
# -*- coding: utf-8 -*-  

HOST = "localhost"
PORT = 4223
UID = "he6" # Change to your UID
dis = "kTk" # Change to your UID

DIGITS = [0x3f,0x06,0x5b,0x4f,
  0x66,0x6d,0x7d,0x07,
  0x7f,0x6f,0x77,0x7c,
  0x39,0x5e,0x79,0x71] # // 0~9,A,b,C,d,E,F

from tinkerforge.ip_connection import IPConnection
from tinkerforge.bricklet_io4 import IO4
from tinkerforge.bricklet_segment_display_4x7 import SegmentDisplay4x7

import time

if __name__ == "__main__":
    ipcon = IPConnection() # Create IP connection
    io = IO4(UID, ipcon) # Create device object
    sd4x7 = SegmentDisplay4x7(dis, ipcon) # Create device object

    ipcon.connect(HOST, PORT) # Connect to brickd
    # Don't use device before ipcon is connected

    # Set pin 1 to output low
    io.set_configuration(1 << 1, 'o', False)

    # Set pin 2 and 3 to output high
    io.set_configuration((1 << 2) | (1 << 3), 'o', True)

    try:
        io.set_edge_count_config(1, io.EDGE_TYPE_RISING, 1)
        ii = True
        while True:
            print('Edge count: {0}'.format(io.get_edge_count(0, ii)))
            compteur = format(io.get_edge_count(0, ii))
            compteur_string = "0" +"0" +compteur
            string = str(compteur_string)
            sub1 = int(string[0])
            sub2 = int(string[1])
            sub3 = int(string[2])

    if int(compteur) < 10 :
                segments = (DIGITS[0], DIGITS[sub1], DIGITS[sub2], DIGITS[sub3])
            sd4x7.set_segments(segments, 0, False)				
            elif int(compteur) >= 10:
	        sub4 = int(string[3])
			segments = (DIGITS[sub1], DIGITS[sub2], DIGITS[sub3], DIGITS[sub4])
                sd4x7.set_segments(segments, 0, False)
            elif int(compteur) >= 100:
                sub5 = int(string[4])
                segments = (DIGITS[sub2], DIGITS[sub3], DIGITS[sub4], DIGITS[sub5])
                sd4x7.set_segments(segments, 0, False)                    
            time.sleep(0.5)
            ii = False
    finally:
        ipcon.disconnect()
