Beginner Recommended Method*
Step-1: Go to this site https://nodemcu-build.com/
Step-2: Two times enter your e-mail address (You will get a status about building the firmware)
Step 3: Select branch to build from (Recommended choose master always)
Step-4: Select modules to include( More than 40+ NodeMCU Lua Modules are available, Select depends upon your application development)
Step-5: Miscellaneous options (Recommended for beginner : Don’t select any option )
Step-6: Click the Start Your Build button
Step-7: Open your email ID (What you gave before)
Step 8: you will get an email about firmware building started and finished notification. In the finished Notification mail, you can download float and integer type NodeMCU .bin firmware file.
If you have many custom NodeMCU firmware, but the firmware name does not contain the details of info about what the NodeMCU module libraries are present. This article explains ESP8266 NodeMCU – How to know firmware information?, if ESPlorer works fine means ESP8266 returns the firmware details, some times ESPlorer IDE does not auto-detect the firmware details. so you should note that your custom NodeMCU firmware details yourself. This post will help to firmware details list easily by using small code.
The NodeMCU firmware is designed to work with the Lua scripting language. Lua is a lightweight and powerful scripting language that is well-suited for embedded systems.
The firmware is often used in conjunction with the NodeMCU development kit, which includes the ESP8266 WiFi module and a USB-to-Serial converter. The kit simplifies the development process and makes it easy to upload Lua scripts to the ESP8266
Lua RTOS is an open-source real-time operating system (RTOS) designed to run Lua applications on microcontrollers and other embedded systems. It aims to provide a lightweight and efficient platform for developing embedded applications with Lua scripting capabilities.Here will discuss ESP32 Lua RTOS Flash Firmware tutorial.
Overall, Lua RTOS is a versatile and lightweight operating system that empowers developers to build embedded applications with Lua scripting capabilities. Its integration with popular microcontroller platforms and active community support make it a compelling choice for IoT and embedded systems development. We tested with EPSressif ESP-Wroom-32 Dev Board and ESP32 Core firmware with the ESPressif Flash tool.
