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] Both the firmware and prototyping board designs are open source. [8] The firmware uses the Lua scripting language. The firmware is based on the eLua ...
This allows Lua to be used for packet filtering and creating device drivers. [20] [21] [22] nmap network security scanner uses Lua as the basis for its scripting language, called nse. [23] NodeMCU uses Lua in hardware. NodeMCU is an open source hardware platform, which can run Lua directly on the ESP8266 Wi-Fi SoC. [24] NUT allows Applications ...
SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
This help-page, Help:Lua debugging, explains issues of writing Lua script and debugging the source code, to remove errors or improve performance. Because Lua is a "semi-compiled" interpreted language, it does not prescreen for all common syntax errors, nor detect misspelled variables, which are only found at runtime when seeing the " Script ...
Lua (/ ˈ l uː ə / LOO-ə; from Portuguese: lua meaning moon) is a lightweight, high-level, multi-paradigm programming language designed mainly for embedded use in applications. [3] 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 ...
The Lua language has allowed misspelled, or uninitialized, variables to be used in a script which can eventually cause "script error" while giving no other indication of the misspelled name or invalid data.
This page explains different methods for creating, controlling and preventing line breaks and word wraps in Wikipedia articles and pages.. When a paragraph or line of text is too long to fit on one line, web browsers, like many other programs, automatically wrap the text to the next line.
A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
