MCS-51 has 111 orders with 49 pieces of single-byte command type, 45 pieces of two-byte type commands, and 17 pieces of three-byte command type. This command can be grouped into four groups based on their function. MCS-51 has instructions with considerable amounts. Instructions can be incorporated into several groups. A list of the group can be seen in the table ...

Microcontroller can be likened to a computer that is in a special chip or a computer with a single chip. The word ‘micro’ claim that a piece of equipment that is small and the word ‘Controller (controller)’ states that this tool is used to control one or more functions of an object, event or process. This is also called an ...

Programming using assembly language (low level languages) requires an understanding of the register, including the name of each register of the controller chip used and the structure of the register itself. Physically, the work of a microcontroller can be described as a cycle of reading instructions stored in memory. Microcontroller specify the address of the program memory to be read, ...

Microprocessors can not stand alone components to process the data, perform calculations, requires other components, so-called system microprocessor or microcomputer. The microcomputer architecture can be seen in the image below: Figure 2 Architecture microcomputers Microprocessor / CPU Microprocessor or CPU is the “brain” which is the main control of all operations in the computer system. Microprocessor taking the binary instructions ...

The transducer / potentiometric sensor is an electromechanical device containing a resistance element connected by a movable slide contact. The sliding contact movement produces a linear, logarithmic, exponential change of resistance, and so on, depending on the way in which the resistance wire is rolled. Potentiometers available on the market consist of several types, namely carbon potentiometers, wire wound potentiometers ...
