Socket programming with TCP using Micropython in ESP8266

Keywords: Socket, Socket programming, TCP/UDP Continuation to🤔socket programming. There are two widely used Socket types, stream sockets, and datagram sockets. Stream sockets treat communications as a continuous stream of characters, while datagram sockets have to read entire messages at once. Each uses its own communications protocol. Stream sockets use TCP (Transmission Control Protocol), which is a reliable, stream oriented protocol, and datagram sockets use UDP (Unix Datagram Protocol), which is unreliable and message oriented. TCP socket runs on top of IP (Internet Protocol). TCP is a connection-oriented communication protocol. What is…

Socket Programming in ESP8266 using MicroPython

Keywords: Socket, Socket programming, TCP/UDP   Dictionary meaning of a Socket – an electrical device receiving a plug or light bulb to make a connection. In computer terminology, when a computer program needs to connect to Internet, it uses a software component called a socket. The socket opens the network connection for the program, allowing data to be read and written over the network. Please note that these sockets are software networking sockets, unlike hardware sockets these sockets will not give any shock ☠ 😄. When two computers or processes…

Interrupts in ESP8266 using MicroPython

Keywords: Interrupts, GPIO, ESP8266, MicroPython, uPyCraft Prerequisites Complete set up of uPyCraftIDE Hardware – ESP8266 Dictionary meaning of Interrupt is to break some continuity. If we relate this to micro controller terminology this means when an interrupt happens, the processor stops the execution of the main program to execute a task or process or thread, and then gets back to the main program. Hardware interrupt A hardware interrupt is an electronic alerting signal sent to the micro controller from an external device, like a button or an external peripheral. For…

Servo Motor control using MicroPython

Keywords: DC Motor control, ESP8266, MicroPython, uPyCraft, GPIO control, PWM control using micro python, ESP32, Servo Motor, DC motor basics, Applications of DC motors I am with Electrical background and have my love towards Motors. I wondered many times how to choose a low power DC motor in any Embedded Application. Here is my version of DC motors with Micro-controllers concept and how to control a ‘Servo motor’ using ESP8266 using MicroPython. Before that I want to explain basics like actuator, motor, BLDC, PMDC etc. ACTUATOR: Actuator is a device…

Getting started with Micropython for Microcontrollers

Keywords: ESP8266, MicroPython, COM port for ESP8266 not detected, uPyCraft, GPIO control, IDE for micro python, ESP32  Have you ever wondered why do we need Python for micro controllers ??? Yes you got it right it is widely used language for Machine learning and Artificial Intelligence. With increasing market in Data Science, Machine Learning and Big Data, I being an Embedded Engineer gave a thought and made some use cases which requires a combination of hardware and software mainly python. The simplicity of the Python programming language makes MicroPython an…
