Many of the students out there who already know about 8051 controllers will be surprised to see this book ranked as #1 over the top of Mazidi and Ayala I will say this is one of the best books to get started with 8051 micro controller. The author Subrata Ghoshal has done an amazing job with this book that any layman can get a great idea about micro controllers and its working. You only need to have an idea of the basic stuffs...

Microcontrollers: What pins are used to upload a program to a 8051 IC?

By s On 07:52 With 2 comments:

You need total four pins of the 8051 (P89V51RD2). viz RESET, TxD, RxD, GND (of course IC should be properly powered). Connect RxD of serial port of computer to TxD of 8051, TxD of serial port of computer to RxD of 8051, DTR of serial port of computer to RST pin of 8051 (all through RS232 interface only). Ground pins of both should be shorted. (adsbygoogle = window.adsbygoogle || []).push({}); The basic need of P89V51RD2 to be...

Is c knowledge necessary for 8051?

By s On 07:48 With 3 comments:

This the simplest Microcontroller to start learning C programming on Embedded Systems. But you need not be a master in C. If you know few things like Declaration, Assignment, Statements and Decision Making. Start with simple program. But practice every day. Conclusion : Today's Embedded world C is necessary for 8051.

Why don't the transformers work with a dc supply?

By s On 21:38 With 1 comment:

A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it. The strength of the magnetism (which has the rather technical name of magnetic flux density) is directly related to the size of the electric current. So the bigger the current, the stronger the magnetic field. Now there's...

Embedded Computer Systems

By s On 05:52 With 3 comments:

An embedded system is a special-purpose system in which the computer is completely encapsulated by the device it controls. Unlike a general-purpose computer, such as a personal computer, an embedded system performs pre-defined tasks, usually with very specific requirements. Since the system is dedicated to a specific task, design engineers can optimize it, reducing the size and cost of the product. Embedded systems are often mass-produced,...

What is embedded software? is most asked question now days. Most of Electronics engineers don't know What is embedded software? There no perfect answer for What is embedded software? here we had tried to answer What is embedded software?

some salient features of the 8051 microcontroller

By s On 23:40 With 2 comments:

On-chip RAM: Random access memory of 128 byte is used for data storage in 8051. RAM as a non-volatile memory consists of register banks, stacks for temporary data storage and some special function registers. On-chip ROM: 8051 consists of 4KB ROM for program storage. ROM as a volatile memory helps in permanent data storage. Timers and Counters: Timer helps in providing delay between the events. In 8051, there are two timer pins T0, T1. If these pins are used in the counter mode, we can count the external pulses. In T0, it...

Is 8051 worth studying now?

By s On 21:55 With 1 comment:

First one have to spearate peripherals from CPU, you can put simple peripherals around an 8051 and extremely complex ones around a Cortex-M4 and vica versa. Selecting a device with simple peripherals should be part of the criteria when selecting a part to use for an intro training (Save the bluetooth, RF, USB ++ peripherals for the later courses). The 8051 is an old single accumulator CPU and it is outdated in regards to both performance and power consumption. The only adoption we see of it today is people who have...

What are the differences in detail between ATmega 16 and 8051 microcontroller, which of these two is better?

By s On 12:28 With 3 comments:

Both are micro-controllers so fundamentally they both are same. But what makes them differ is how and for what you want to use them.8051, is a very good micro-controller to learn mainstream embedded systems(or at least what they teach in colleges),It is powerful enough to run most of your projects.There are now a days there are advanced variants(S8051XC3 ).But on comparing the original 8051(or even better AT89C51RD2,which is optimized...
