I'll respond in English, but don't worry, I won't get on your nerves, Grandma!

You're looking for a PDF about Python and ESP8266? Well, you've come to the right place! Here's some essential information that will help you get started:

What is ESP8266?

ESP8266 is a low-cost Wi-Fi module designed by Espressif Systems. It's widely used in IoT projects due to its low power consumption and affordability. The ESP8266 chip includes a built-in Wi-Fi transceiver, which makes it an excellent choice for wireless communication.

What is Python?

Python is a high-level programming language known for its simplicity, readability, and ease of use. It's widely used in various applications such as web development, data analysis, artificial intelligence, and IoT projects.

Using Python with ESP8266: A Beginner's Guide

Install the necessary libraries: You'll need to install the micropython library for ESP8266, which provides a Python interpreter that runs on the ESP chip. Follow these steps: Install the micropython library using pip (Python package manager): pip install micropython Clone the ESP8266 firmware repository: git clone https://github.com/espressif/esp-idf.git Copy the micropython folder from the cloned repository to your project directory Write Python code: Now that you have the necessary libraries, it's time to write some Python code! Create a new file (e.g., main.py) and start coding: 
import esp
Initialize the ESP8266 module

esp.init()

Set the Wi-Fi credentials

wifi_ssid = "your_wifi_ssid"


wifi_password = "your_wifi_password"

Connect to the WiFi network

esp.connect(wifi_ssid, wifi_password)

Send a GET request to a server (e.g., httpbin.org)

import requests


response = requests.get("http://httpbin.org/get")


print(response.text)

Disconnect from the WiFi network

esp.disconnect()
Flash the firmware: Once you've written your Python code, it's time to flash it onto the ESP8266 chip using a USB-to-TTL programmer (e.g., FTDI Friend) and a serial console tool like esptool.

Conclusion

Using Python with ESP8266 is an exciting way to bring your IoT projects to life. With this guide, you should have a solid foundation for building wireless applications that integrate the power of Python and ESP8266.

Now, go forth and code some magic!

Can NodeMCU run in Python?

NodeMCU is a microcontroller-based board that is widely used for IoT projects. By default, NodeMCU boards come with the Lua scripting language pre-installed. However, it's possible to run NodeMCU using other programming languages, including Python.

One way to run Python on NodeMCU is by using a firmware called "Espressif's Python Interpreter" which allows you to run Python scripts directly on the NodeMCU board. This firmware is specifically designed for ESP32 and ESP8266 microcontrollers, which are the same ones used in NodeMCU boards.

To use this interpreter, you'll need to:

Install the latest version of the Espressif's Python Interpreter using the Arduino IDE. Create a new Python script (.py file) using any text editor or IDE that supports Python programming. Upload the Python script to your NodeMCU board using the Arduino IDE.

Once uploaded, you can run your Python script directly on the NodeMCU board. The interpreter supports most Python 3.x features, including modules, classes, and exceptions. However, please note that some modules or libraries might not work as expected due to hardware limitations or compatibility issues.

Another option is to use a library called "MicroPython" which is a lean and efficient implementation of the Python 3 programming language for microcontrollers. MicroPython can be flashed onto your NodeMCU board, allowing you to run Python scripts directly on the device.

To use MicroPython with NodeMCU, you'll need:

Flash the MicroPython firmware onto your NodeMCU board using a tool like esptool or pyserial. Create a new Python script (.py file) using any text editor or IDE that supports Python programming. Upload the Python script to your NodeMCU board using a serial communication tool like PuTTY or CoolTerm.

Both methods allow you to run Python scripts on your NodeMCU board, but they have some limitations and differences in terms of functionality and compatibility. For example, Espressif's Python Interpreter is more geared towards running Python scripts directly on the NodeMCU board, while MicroPython offers a more lightweight and efficient implementation of Python.

In summary, NodeMCU can indeed run using Python, either by using Espressif's Python Interpreter or MicroPython. Both options offer a way to program your NodeMCU board using Python, but they have their own strengths and limitations.
