Apr 11, 2014 · Doing so will allow your Raspberry Pi to interact in the real world, making it possible to build a robot, turn on a fan on a hot day or even drop a treat for your cat or dog while your away. I haven't checked the L239D's datasheet but aside from pin differences (on the motor driver side) I think the code should work the same. In our case, we are dealing with an incremental encoder. I have a DC motor that is running, and I want to get the value of my encoder after lets say 3 seconds, but I am not being able to get the values, I get continues values until I stop with crtl+c. is_pressed: eventq. Works only on interrupts because all RPi pins allow that. GPIO as GPIO import threading from time import sleep # GPIO Ports Enc_A = 4 # Encoder input A: input GPIO 4 Enc_B = 14 # Encoder input B: input GPIO 14 Rotary_counter = 0 # Start counting from 0 Current_A = 1 # Assume that rotary switch is not Current_B = 1 # moving while we init software LockRotary = threading.
