Microprocessor – controlled temperature system is used to Read the temperature in a room Display the temperature at LCD/LED panel Turn-on a fan if the temperature is above the limit. Turn-on a heater if the temperature is...
Memory Interfacing While executing a program, the microprocessor needs to access memory frequently to read instruction code and data stored in memory; the interfacing circuit enables that access. Memory has some signal...
Data manipulation instructions enable the PLCs to take on additional characteristics that are beyond the conventional relay equivalent instruction. It allows the movement, manipulation or storage of data in either single or...
INTRODUCTION TO DESIGN USING COMPENSATORS – Linear System Design The control systems are designed to perform specific tasks in linear system design. The requirements of a control system are usually specified as performance...
Interfacing Microcontroller 8225 The INTEL 8255 is a general purpose programmable peripheral interface. It is used to perform a variety of input/output functions in a microcomputer system. It is a 40 pin DIP IC. It requires +5V...
Bit addresses for I/O – Microcontroller 8051 Microcontroller 8051 contains four I/O ports. They are Port 0, Port 1, Port 2 and Port 3. All ports are 8 bit ports. So totally it contains 32 I/O pins that connects the 8051 to...
Assembler and Addressing Mode 8051 Assembly language is the human language most closely tied to machine language. addressing mode 8051 It is usually written in instruction mnemonics. Once the program has been written in mnemonis...
COMPONENTS OF AUTOMATIC CONTROL SYSTEM The basic components of an automatic control system are error detector, Amplifier and Controller, Actuator (power actuator), plant and sensor or Feedback system. The block diagram of an...
Introduction to Instruction Set Architecture of 8051 Generally microprocessor alone is not a self-sufficient system. Instruction Set Architecture of 8051 It requires other components like memory and input/output devices to form a...
