How to start the OneGPIO server python code?

[doutv]

Thanks for your help! I've figured out the problem and run it on my Nano successfully.
Below are the problems I came across and their solutions. Maybe it can help others.

can't find s3a command in cmd

I use python -m pip install xxx --user to install python package, but maybe it will cause some problems.
https://stackoverflow.com/questions/58386953/pip3-typeerror-module-object-is-not-callable-after-update
So I use pip install s3-extend under administrator mode and it works for me.
I think it's because --user will install the python package in a different folder like C:\Users\XXX\AppData\Roaming\Python\Python37\Scripts
Without --user and run in administrator mode:
C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64

subprocess.py error

modify subprocess.py

_init__:
shell=False to shell=True

I don't know the reason.

my environment

Windows10

Again, Thanks for your devotion! I will help you complete this good project.

The Uno is the only officially supported board, but I am willing to look at your issue. Please follow these troubleshooting instructions and let me know if there are any exceptions reported on any window and what you see on the ardgw window.

Also, did you load FirmataExpress on the Nano?

I have load FirmataExpress on Nano.
Actually, I don't know how to start s3-extend on my computer. I download your code and run s3a.py. Is it the correct way to start python server?

Following your tutorial, I open cmd on Win10 , enter the command s3a and it says that it isn't a program or command. Should I add s3-extend file to my system path?

Step 3: Start the OneGPIO server code by opening a terminal window for each microcontroller you wish to use and then enter the command for the specific micro-controller:

s3a - for the Arduino
s3c - for the Adafruit Circuit Playground Express
s3e - for the ESP-8266
s3p - for the Picoboard
s3r - for the Raspberry Pi

Thanks for your help, your project is great when I'm looking for a scratch+arduino platform.

You should not need to change your system path. To make sure that Python was installed on the path,
open a command window and type:

python

If you see a banner that shows python 3 is running you can close Python and should be able to do the following:

1. In a command window type:

pip install s3-extend

This will install s3-extend and all of the packages it uses. It will also install s3a as an executable. So to start the extension for Arduino, in a command window enter:

s3a

Please let me know if you are still having an issue, and if not, please close this issue.
