An embedded system is a combination of computer hardware and software designed to do specific functions within larger equipment. The heavy equipment used in industries, automobiles, medical procedures, household appliances, and mobile devices use embedded systems. Most embedded systems use a RISC family microcontroller, such as PIC 16F84, Atmel 8051, or Motorola 68HC11. Several input and output devices can be connected to the embedded system's microcontrollers, such as an LCD display, keypad, printer, and sensor. These devices can control several other devices such as fans, motors, bulbs, washing machines, ovens, AC controllers, cars, printers, and so much more.
To program a microcontroller to do a specific task, the microcontroller is interfaced with a PC by connecting it to a slot. An assembly program, or Embedded C, can be used to write and burn the program onto the microcontroller. The programs can be stored in the microcontroller's EPROM (short for Erasable Programmable Read-Only Memory). It's an internal, read-only memory that can be programmed and erased when exposed to an ultraviolet light source. We will be developing applications for embedded systems using Embedded C with software such as Keil.
