Now we will see how to convert Hexadecimal number to its ASCII equivalent using 8051. This program can convert 0-9 and A-F to its ASCII value. We know that the ASCII of number 00H is 30H (48D), and ASCII of 09H is39H (57D). So all other numbers are in the range ... Read More

This is one of the methods of representing signed integers in the computer. In this method, the most significant digit (MSD) takes on extra meaning.If the MSD is a 0, we can evaluate the number just as we would interpret any normal unsigned integer.If the MSD is a 1, this ... Read More

Here we will see how to subtract two 8-bit numbers using this microcontroller. The register A(Accumulator) is used as one operand in the operations. There are seven registers R0 – R7 in different register banks. We can use any of them as the second operand.We are taking two number73H and ... Read More

As we have seen there are five different interrupts in 8051. These interrupts are INT0, INT1, TO, T1, TI/RI.There are six states in each machine cycle. These states are S1 to S6. All of the interrupts are sampled at the end of state S5 of each machine cycle. When the ... Read More

The 8251 chip is Universal Synchronous Asynchronous Receiver Transmitter (USART). It acts as a mediator between the microprocessor and peripheral devices. It converts serial data to parallel form and vice versa.

In 8085 Instruction set, SIM (Set Interrupt Mask) and RIM (Read Interrupt Mask) instructions can perform mask and unmask RST7.5, RST6.5, and RST5.5 interrupt pins and can also read their status. In 8085 Instruction set, SIM stands for “Set Interrupt Mask”. It is 1-Byte instruction and it is a multi-purpose instruction. ... Read More

In the 4-bit microprocessor or computer architecture will have a data path width or a highest operand width of 4 bits or a nibble. And also these architectures or microprocessors typically will have a matching register file with registers width of 4 bits and 4-8-bit wide addresses.Most of the first ... Read More

In 8085 Instruction set, In the year 2001, Intel introduced the Itanium processor is the first in a family of 64-bit products. It is capable to meet up most demanding enterprise and high-performance computing applications like e-Commerce security transactions, mechanical computer-aided engineering, large databases and sophisticated scientific and engineering computing.Intel ...
