Python Web Server on MiniZed

A new reference design was recently posted for the MiniZed. Take a look!

Python Web Server on MiniZed

A guide to using a simple Python script to control a basic web server that allows a user to modify GPIO in the MiniZed PS and PL from a browser interface over Wi-Fi.

    This sounds like a worthy execise.  I have not done it, so my input here may simply state what you already know.

    The web server demo you ran only uses the web server to post data to a MiniZed device to change the LEDs.  You want to pass information up from MiniZed, so that is not covered and you may have to find examples of how to upload data from the Python script.

    Also, the LEDs that are controller by this Python script use either the /sys/class/gpio or the /dev/mem interface for GPIO devices (it shows how to do both).  The accelerometer is an I2C device.  And one can use i2c-dev to interface to it using C code using the sample code at this link. https://avnet.egnyte.com/fl/S6F74pOLUr

    I am not sure how this would be done under Python, but you may need to use i2c-tools.  There may be some examples online for doing this, maybe for RPi.  The relevant accelerometer register use is clear in the C example code though.  Someone else may have more pointed advice.  It will be good to know what solutions you discover.
