NodeMCU is an open source firmware for which open source prototyping board designs are available. The name "NodeMCU" combines "node" and "MCU" (micro-controller unit). [8] Strictly speaking, the term "NodeMCU" refers to the firmware rather than the associated development kits. [citation needed]
This allows Lua to be used for packet filtering and creating device drivers. [19] [20] [21] nmap network security scanner uses Lua as the basis for its scripting language, called nse. [22] NodeMCU uses Lua in hardware. NodeMCU is an open source hardware platform, which can run Lua directly on the ESP8266 Wi-Fi SoC. [23] NUT allows Applications ...
Lua is cross-platform software, since the interpreter of compiled bytecode is written in ANSI C, [4] and Lua has a relatively simple C application programming interface to embed it into applications. [5] Lua originated in 1993 as a language for extending software applications to meet the
[3] [4] At a low level, the ESP Easy firmware works the same as the NodeMCU firmware and also provides a very simple operating system on the ESP8266. The main difference between ESP Easy firmware and NodeMCU firmware is that the former is designed as a high-level toolbox that just works out-of-the-box for a pre-defined set of sensors and actuators.
Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...
Almost any problem which occurs when running a Lua module will be reported as "Script error" during program execution, such as invalid data or a misspelled variable name in the Lua source code.
The U.S. Securities and Exchange Commission has given Elon Musk until Monday to respond to an offer to resolve a probe into the billionaire's $44-billion takeover of Twitter in 2022, a source ...
