Ben Boardwalk Project finished phase1

THis started to fail when new if--elif options added. REcast as simpler version. Don't use this version. Use next one called minresponse3.py. See above...

 Ben Boardwalk Project more or less finished phase1. This is temperature and logging data is captured by PC HTML client form from Pi PicoW web server that's doing the logging and the sensing. Early days but structures seem fine and micropython code is relatively organised.

Here is pic of a client session. Just asked for logging data which goes into file dialog query.

The main file is the micropython file bensense12.py. It establishes the AP network, called NAME and awaits query from chrome html form called bensensor5.html. Mostly buttons that cause a cascade of if,elif statements to sort through all the options and return with information that gets printed on the form, like temperature or, new work for me, gets the browser to save a log file, not print it, to via a normal Windows dialog. 

Here's the main program written in micropython using Thonny:

#Worked ok Tue Aug  6 11:04:01 NZST 2024. Can't get other mode to work  Will play with this one.
#Sun Sep  1 11:46:42 NZST 2024. Going to write route finder for all the paths from HTML form
#Mon Sep  2 12:20:06 NZST 2024. Tidied up all loose comments. Now ready for sensors.
#trying tidyup Tue Sep 10 11:06:12 NZST 2024
#Wed Sep 11 11:30:24 NZST 2024. INternal temp seems to be working with html form. ext temp stub done.

------here, below is typical sensor subroutine-----------do_inttemp.py

#do_inttemp

import machine

adcpin = 4

sensor = machine.ADC(adcpin)

def do_inttemp():

    adc_value = sensor.read_u16()

    volt = (3.3/65535) * adc_value

    temperature = 27 - (volt - 0.706)/0.001721

    file = open("bensensor5.html")

    html = file.read()

    file.close()

    html3 = html.replace('**TEMP**',str(round(temperature,1)))

    return html3

  

=============below is function that gets csv file for saving-------

#do_text.py

def do_csv():

    # Attempt to read the my-log.txt file

    try:

        with open('log.csv', 'r') as file:  #('simpleled2.html', 'r')

            log_data = file.read()

    return html3

  

================

To do: Save all the relevat files in pastebin. Done

Next check that the iPhone can run all this in a little chrome browser.

Tidy up code and all the do_xx routines. Some left=over comments etc

Work out why led changes don't work on iPhone but rest pretty good.

Phase 2 would include some of this:

detach picoW and run off batteries at short distance.

Take this into ben enviornemnt and test with iPhone.

Add in breadboard version with oled and DSxx 1-wire temperature sensor.

Create scematic voa EasyEDA then make board for full version.
