How to Setup and Program NodeMCU ESP8266-Complete Guide

2 роки тому

Let’s learn how to setup and program NodeMCU ESP8266 using Arduino IDE. We’ll connect NodeMCU ESP8266 with laptop using MicroUSB cable. And then install ESP8266 specific software packages using board manager in arduino software. This will let us select NodeMCU1.0 ESP-12E module while programming NodeMCU in tools section. And finally, we’ll write arduino program to blink on board led on NodeMCU ESP8266 which is D4 Pin.

I have never had success with the ESP and Arduino IDE in 5 years. Concentrating mostly on RaspberryPi Pico, Waveshare RP2040-One,Zero,Plus w/ LCD, Microchip PICs, Nucleo-STM32 boards with Armmite, a tube of NXP LPC800 an 8 pin DIP Arm Cortex-M0+, STM8 chips running 8 bit eForth. Your instructions made it so easy for such a normally frustrating installation. Now lets see if the Arduino GIGA R1 arriving tomorrow is this simple.

Since NodeMCU is a microcontroller based device you can only run one program at a a time. You can use RTOS real time OS so that you can use multiple task. I hope this may help you. Best wishes!
