Firmware is found in a wide range of computing devices including personal computers, phones, home appliances, vehicles, computer peripherals and in many of the digital chips inside each of these larger systems. Firmware is stored in non-volatile memory – either read-only memory (ROM) or programmable memory such as EPROM, EEPROM, or flash.
An embedded controller is sometimes known as a "Keyboard Controller BIOS", which comes from the fact that the embedded controller evolved from the keyboard controller and often still is used as a keyboard controller. Even today, an ACPI embedded controller communicates with the CPU by using the same I/O ports that keyboard controllers used in ...
Microcontroller. A microcontroller ( MC, UC, or μC) or microcontroller unit ( MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more CPUs ( processor cores) along with memory and programmable input/output peripherals.
Embedded system. An embedded system is a computer system —a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. [ 1][ 2] It is embedded as part of a complete device often including electrical or electronic hardware and ...
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]
PIC (usually pronounced as /pɪk/) is a family of microcontrollers made by Microchip Technology, derived from the PIC1640 [ 1][ 2] originally developed by General Instrument 's Microelectronics Division. The name PIC initially referred to Peripheral Interface Controller, [ 3] and is currently expanded as Programmable Intelligent Computer. [ 4]
Embedded software is computer software, written to control machines or devices that are not typically thought of as computers, commonly known as embedded systems. It is typically specialized for the particular hardware that it runs on and has time and memory constraints. [ 1] This term is sometimes used interchangeably with firmware.
ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
