How to make calculator using 8051 microcontroller?

Design a Simple Calculator with 8051 Microcontroller

1. When you press the (+) button then it will add the two digits.
2. When you press (-) button it will subtract the two digits like 3 – 2 = and it will give you the result.
3. When you press (x) button it will multiply the two digits.

Which microcontroller is used in calculator?

8051 microcontroller
Calculator with 8051 microcontroller circuit diagram Port-1 is used as in input port. 16×2 lcd is interfaced with 8051 micrococntroller in 8-bit mode. 16×2 lcd is connected to port-2 of 89c51 microcontroller. 20Mhz oscillator is used to supply clock source to 89c52 microcontroller.

What is the bit size of the 8051 microcontroller?

8-bit
8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers.

What is the use of 8051 microcontroller?

The 8051 Microcontroller is one of the basic type of microcontroller, designed by Intel in 1980’s. This microcontroller was based on Harvard Architecture and developed primarily for use in embedded systems technology.

When we add two numbers the destination address must always be?

1. When we add two numbers the destination address must always be. Explanation: DAA command adds 6 to the nibble if any of the nibbles becomes greater than 9.

Why is it called 8051 microcontroller?

In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip.

Why microcontroller is used?

Microcontrollers are used in applications requiring repetitive operations such as running the traffic light at an intersection. In this application, the microcontroller’s sole function is to turn lights on and off at predetermined times. Another example is a microwave oven.

How 8051 is programmed?

The 8051 assembly language programming is based on the memory registers. If we want to manipulate data to a processor or controller by performing subtraction, addition, etc., we cannot do that directly in the memory, but it needs registers to process and to store the data.

What is ANL in 8051?

The ANL instruction performs a bitwise logical AND operation between the specified byte or bit operands and stores the result in the destination operand. Note. When this instruction is used to modify an output port, the value used as the port data will be read from the output data latch, not the input pins of the port.

What is Jump Range 8051?

The relative address ranges from 00H to FFH which is divided into forward and backward jumps; that is, within –128 to +127 bytes of memory relative to the address of the current PC (program counter).

Is there a calculator for the 8051 micro controller?

The post provides a simple calculator project code using assembly for 8051 micro-controller. This is a simple one decimal digit calculator which implements only 4 functions: addition (+), subtraction (-), multiplication (x) and division (/). Code, flowchart and Proteus simulation is given in the ‘Downloads’ section at the bottom of this page.

Can a Proteus calculator be used with an 8051 microcontroller?

The Proteus Simulation of this Calculator with 8051 Microcontroller is same as we used for Interfacing of Keypad with 8051 Microcontroller and is shown in below figure: So, you can see we have used the same LCD which is 20×4 and have used the same keypad as did in previous tutorial.

Which is microcontroller is used in speed calculator?

Speed calculation circuit pic18f4680 used optionally pic18f4585 microcontroller used in the pic input signal FPS, MPH as the calculate and 4 × 16 LCD screen displays the software pibasic pro… Read more alculator with Pic 16f877 microcontroller is a comprehensive project.

How do you get 81 on a calculator?

To achieve this result, first press ‘9’ from the keypad. Then press ‘x’ and then press ‘9’ again. After that, on pressing ‘=’ from the keypad the result ’81’ is automatically displayed on the screen. Then after seconds the screen cleared automatically for next try.
