After studying the ESP8266WiFi to control the microcontroller connected to a wireless network in an STA and SoftAP form, then learned how to use the WiFiClient to use the esp8266 as a client node. This time, it’s about WiFiServer to make esp8266 act as a service node or Server. The example in this article is to create an internal network system by using 3 esp8266 to act as SoftAP, Server and Client as shown in Figure 1.
After mentioning the ESP8266WiFi class in the previous article. This time, let’s learn how to use the WiFiClient class to write programs on the client side that link to a service or server.
This article is to learn how to use the Pin class which is a subclass in the machine class of Micropython for use with ESP8266 or ESP32 microcontrollers.
This article is a tutorial on how to use esp and esp32 classes, which are dedicated classes for esp8266 and esp32 microcontrollers to access specific features and the internal abilities of the two chips.
This article describes how Adafruit’s DHT Sensor library is compatible with all Arduino-compatible architectures, making it easier to deploy DHT sensors for humidity and temperature readings across multiple platforms. This article has tested with ESP32, ESP8266, Arduino UNO and stm32f103c and found that it can be used without modifying the code in the working part or having to modify the source code to make it compatible with the platform.
This article describes programming to use the DS1302 (Figure 1), another RTC (Real-Time Clock) IC (previously written to PCF8583 in Python and Arduino C++). And it is a module that is popular for beginners because it is a module in the learning kit of Arduino, IoT, 37-Sensors or 45 Sensors, etc.
From a Python article on how to use pcf8583 as an RTC (Real-time clock) board, we have rewritten the code for Arduino’s C++ programming with esp8266, esp32 and stm32.
This article describes the interrupt and intercept principle with MicroPython, experimented with ESP8266 and ESP32 as a guide to programming an external event response without waiting for the work in progress completed first.
This article describes the MicroPython GY-271 digital compass sensor for use with the ESP8266 or ESP32 (we have experimented with STM32F411CEU6 with Raspberry Pi 3B+ and 4B and found that it can be used as well) to set the operation and read the X,Y and Z axis values from the sensor, then calculate it as the degree of north.
This article is about connecting the ESP8266 to an OLED, which is a two-color graphic LED, where 0 represents blank and 1 represents color dot. It is connected to the microcontroller via the I2C bus. How to use it and its functions are discussed as a guide and reference material for further implementation.
