testAll.py &SmartPlantPi.py dont work IOError

Let's look at what version of the Raspbian operating system you are running:

do this from a company line window and post the results.

cat /etc/os-release

I'm just wondering if that is the problem.

I wonder if it is Stretch. I have a stretch system here in the office and will check it later today.

BP

All connected. The i2cdetect -y 1 gives the correct values.

sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

and when I run sudo python testAll.py I got

pi@raspberrypi:~/SDL_Pi_SmartPlantPi $ sudo python testAll.py

and when I run sudo python SmartPlantPi.py

Raspberry Pi 3 the os release is:

pi@raspberrypi:~ $ cat /etc/os-release

the SDL_Pi_SmartPlantPi version is March 20, 2018: Release Version 021

I'm a python newbie of sorts. I'm encountering a lot of syntax errors in the code from print functions not having () and numerous indentation and tab disparities. I've looked at githubs raw files and see the same errors. Help! Thanks.

hello,
i get the same exact error as scottaandy.

the i2cdetect -y 1 command gives the expected results:

0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- --
40: 40 -- -- -- -- -- -- -- 48 -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: 60 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

but when i type sudo python testAll.py i get the error:

Traceback (most recent call last):
File "testAll.py", line 94, in <module>
rotary = SDL_Pi_RotaryButton.SDL_Pi_RotaryButton()

My python version:

Type "help", "copyright", "credits" or "license" for more information.

and i have the raspberry pi 3 B

i have no knowledge of Python and i would like to demonstrate smartplantPi to my nephews asap. Please help.

are we the customers ourselves doing the python debugging now? i thought the code was supposed to work straight out-of-the-box, at least that's the impression i got from the amazon product description.

Val,

"are we the customers ourselves doing the python debugging now? i thought the code was supposed to work straight out-of-the-box, at least that's the impression i got from the amazon product description."

When you are dealing with a complex ecosystem like the Raspberry Pi (Stretch, Jessie, etc) with multiple types of hardware (PI3 B, Pi3B+, the Zero, ZeroW and others....), changes in the OS or hardware breaks the software.

SmartPlantPi works perfectly on our test systems, but there are dozens of things people can do to their system to break applications (like not install I2C for example).    When they updated to the Stretch OS, it broke the software and we had to update.   

It's a moving target.  



What we have found is that with some tech support, we generally can help people figure out what is going on.    We are going to look at this latest:
GPIO.add_event_detect(SDL_Pi_RotaryButton_Enc_A,GPIO.RISING,callback=self.Enc_EventHandler)
RuntimeError: Failed to add edge detection

during the next week.   It looks like something is not installed (like the GPIO library) in the customers OS.   

As soon as we can duplicate a problem, it's generally easy to fix.  We haven't duplicated this, which makes us think it is a library.

BP

any update on the moving target?
