Micropython requests via Thonny

 Pi Pico sets up local AP network and sends some led buttons yo browser request on 192.168.4.1

Then clicking the buttons causes Pico to receive extra information of URL like /ledon and /ledoff so that the pico can interrogate this response code and change leds or do anything else. Would really like this to initiate an sending of a data-logging file in text that sends lots of sensor data back to browser to be handled by other software like Excel.

Now comes the HTML used above....


<!DOCTYPE html>

<html>

<head>

    <title>Raspberry Pi Pico Simple LED</title>

</head>

<body>

<p>Click the buttons to control the LED</p>

<input type="button" onclick="document.location='/ledon'" value="TURN LED ONnnnn"/>

<p></p>

<input type="button" onclick="document.location='/ledoff'" value="TURN LED OFF"/>

<p></p>

<p>The LED is **ledState**</p>

</body>

</html>

----------------------------Now comes the responses that the pic got from PC browser, Chrome. Buttons were pressed.

Reading LittleFS file into buffer for sending

 Reading LittleFS file into buffer for sending to another ESP32 via ESP Now. Created dummy file 1321 bytes long with "sensor" information in the form like this:     uint8_t sensorData1[] = "[ 00 12:05:12:06:01 22 33 44 \n"; Red stuff above is timestamp to later get in real time from DS3231.  Blue stuff is dummy sensor information, two ascii chars representing 00 to 99. Black stuff is just formatting chars and spaces. The following program reads in about 43 lines of sensor information as above and puts it into LittleFS file called sensorReadings.txt. This file then gets cut up into 200 byte chunks (via sendBuf[200] ) and gets sent to dummy sender file called sendNowBuf(). No actual sending takes place, so next sub-project is to send the 200 byte chunks one by one via ESPNow to second ESP32. //41 From Arduino Examples/mnt/c/Users/Dell/Documents/Arduino/Working202411/LITTLEFS_test2/LITTLEFS_test2.ino #include <Arduino.h> #include "FS.h" #include <Li...
