Hello,
I noticed that PWM, P8_13, on the BBBW is having issues with the
Adafruit_BBIO framework. I have this software I found within a book I
purchased, "Getting Started with BeagleBone" (Richardson 2014). Anyway, The
software works without me using PWM but I would like to use PWM to make a
LED go bright to dim just by using the web page format found via Flask (a
Python Module). The error I incurred while running this software was this
and only this: *RuntimeError: Problem with a sysfs file.*
So, here is the software:
* from flask import Flask, render_template*
* app = Flask(__name__)*
* import Adafruit_BBIO.GPIO as GPIO*
* import Adafruit_BBIO.PWM as PWM*
* PWM.start("P8_13", 0.0)*
* @app.route("/")*
* def hello():*
* if GPIO.input(P8_11):*
* doorStatus = "open"*
* else:*
* doorStatus = "closed"*
* templateData = {*
* 'doorStatus': doorStatus,*
* }*
* return render_template('main-door.html', **templateData)*
* @app.route('/ledLevel/<level>')*
* def pin_state(level):*
* PWM.set_duty_cycle("P8_13", float(level))*
* return "LED level set to " + "."*
* if __name__ == "__main__":*
* app.run(host='192.168.7.2', port=5000, debug=True)*
So, please give advice or if you are using Adafruit_BBIO, please allow me
some "behind-the-scenes" look at the software to change to get things
"cracking."
Seth
P.S. I am sure there is a cure. Direct me to the software and I can start
on it. I found a link to the sourceforge items and software. Is this where
I should begin?
