ESP32+PS2 wireless controller adapter board+microPython
When I bought it, I came with a connector. The wire inside this connector is thick, and ordinary DuPont wire cannot be used. Be sure not to connect the positive and negative poles incorrectly. You can also input 3.3v voltage: from machine import Pin import time di = Pin(26,Pin.IN,Pin.PULL_UP) # dat/di Connect ESP32 to pin […]
“MicroPython implements I2S support on microcontrollers: Detailed guide with complete Python example code
Part 1: Introduction to MicroPython and Microcontrollers 1. Introduction to MicroPython MicroPython is a streamlined, efficient, and fast implementation of Python 3, designed for microcontrollers and restricted environments. Compared to traditional Python, MicroPython is optimized to run on resource-constrained devices, meaning it can run on devices with only a few tens of KB of RAM […]

20-MicroPython+ESP32 implements MQTT communication
(1) Experiment purpose This experiment aims to use the MicroPython programming language to control the ESP32 module to implement MQTT communication. MicroPython provides support for the MQTT (Message Queuing Telemetry Transport) protocol, making it easy to implement message passing and communication between devices in embedded systems and IoT applications. MQTT is a lightweight publish/subscribe messaging […]
ESP32-S3 builds micropython development environment, firmware compilation and burning
Brief description I got my hands on an ESP32-S3-DevKitC-1 development board officially launched by Espressif Systems, and found that the overall performance of ESP32-S3 has been significantly improved compared to the previous two generations, including wifi and Bluetooth functions, and more sufficient peripheral expansion capabilities. It can be seen that it will occupy a greater […]
