FatFs is a lightweight software library for microcontrollers and embedded systems that implements FAT/exFAT file system support. [1] Written on pure ANSI C, FatFs is platform-independent and easy to port on many hardware platforms such as 8051, PIC, AVR, ARM, Z80.
A limit switch with a roller-lever operator; this is installed on a gate on a canal lock, and indicates the position of a gate to a control system A limit switch mounted on a moving part of a bridge In electrical engineering , a limit switch is a switch operated by the motion of a machine part or the presence of an object.
AVRDUDE (AVR Downloader/UploaDEr) runs on Linux, FreeBSD, Windows, and Mac OS X, and supports a variety of in-system programming hardware, including Atmel AVRISP mkII, Atmel JTAG ICE, older Atmel serial-port based programmers, and various third-party and "do-it-yourself" programmers.

There is usually limited support for arrays and loops, often resulting in duplication of code to express cases that in other languages would call for use of indexed variables. As microprocessors have become more powerful, notations such as sequential function charts and function block diagrams can replace ladder logic for some limited applications.
A phase-locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies keeping the input and output frequencies the same, thus a phase-locked loop can also track an input frequency.
ChibiOS/RT is designed for embedded applications on microcontrollers of 8-, 16-, and 32-bits.Size and execution efficiency are the main project goals. [3] As reference, the kernel size can range from a minimum of 1.2 KiB up to a maximum of 5.5 KiB with all the subsystems activated on a STM32 Cortex-M3 processor.
Fritzing's schematic view. The software was created with inspiration from the Processing programming language and the Arduino microcontroller [6] and allows a designer, artist, researcher, or hobbyist to document their Arduino-based prototype and create a PCB layout for manufacturing.
