A "core" is the collection of software components required by the Board Manager and the Arduino IDE to compile an Arduino C/C++ source file for the target MCU's machine language. They did this with the introduction of the Board Manager and the SAM Core. Related projects ESP8266 Arduino Core Īs began developing new MCU boards based on non- AVR processors like the ARM/SAM MCU used in the Arduino Due, they needed to modify the Arduino IDE so it would be relatively easy to change the IDE to support alternate toolchains to allow Arduino C/C++ to be compiled for these new processors. By the summer of 2016 the NodeMCU included more than 40 different modules.

In the summer of 2015 the original creators abandoned the firmware project and a group of independent contributors took over.
#Random arduino update
Another important update was made on, when Devsaurus ported the u8glib to the NodeMCU project, enabling NodeMCU to easily drive LCD, Screen, OLED, even VGA displays. Later that month, Tuan PM ported MQTT client library from Contiki to the ESP8266 SoC platform, and committed to NodeMCU project, then NodeMCU was able to support the MQTT IoT protocol, using Lua to access the MQTT broker. Two months later, the project expanded to include an open-hardware platform when developer Huang R committed the gerber file of an ESP8266 board, named devkit v0.9. NodeMCU started on, when Hong committed the first file of nodemcu-firmware to GitHub. On December 30, 2013, Espressif Systems began production of the ESP8266. NodeMCU was created shortly after the ESP8266 came out. There are two available versions of NodeMCU as version 0.9 & 1.0 where the version 0.9 contains ESP-12 and version 1.0 contains ESP-12E where E stands for "Enhanced". The design was initially based on the ESP-12 module of the ESP8266, which is a Wi-Fi SoC integrated with a Tensilica Xtensa LX106 core, widely used in IoT applications (see related projects). The choice of the DIP format allows for easy prototyping on breadboards. The prototyping hardware typically used is a circuit board functioning as a dual in-line package (DIP) which integrates a USB controller with a smaller surface-mounted board containing the MCU and antenna. Support for the 32-bit ESP32 has also been implemented. Due to resource constraints, users need to select the modules relevant for their project and build a firmware tailored to their needs. It uses many open source projects, such as lua-cjson and SPIFFS. The firmware is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. The firmware uses the Lua scripting language. īoth the firmware and prototyping board designs are open source. Strictly speaking, the term "NodeMCU" refers to the firmware rather than the associated development kits. The name "NodeMCU" combines " node" and "MCU" ( micro-controller unit). In most cases, a random seed is preferred, which can be obtained by reading an unconnected analog pin.NodeMCU is an open source firmware for which open source prototyping board designs are available. randomSeed(5)), the sequence of random numbers generated by the sketch will repeat each time it is run. If randomSeed() is called with a fixed value (eg.
