Embedded C Programming Compilers For 8051 Microcontroller

  • Posted on October 23, 2017 at 8:52 pm

Todays sophisticated computers are developed as embedded systems so that they can be complimentarily used in mobile devices and electronic appliances. The microcontroller turns out to be the key element in an embedded system. Actually a microcontroller is a microprocessor giving more emphasis on the input & output operations. It controls the operation of electronic devices by giving them access to communication, measurements and switching information. Thus a microcontroller is regarded as a device controller. Intels 8051 microcontroller is among the oldest members of the microcontroller family, yet is very popular among users. Technical analysts attribute its popularity to its amazing architecture. Some of the reputed computer manufacturers like NXP, Silicon Labs & Atmel are still using 8051 microcontroller as the basis of their microcontrollers.

The 8051 microcontroller has a complicated memory structure that requires special software instructions to access it segment wise. Therefore special kind of compliers needs to be designed to make the memory accessible. Since the 8051 microcontroller is widely used in IT industry & many projects as well, companies have created their own 8051 microcontroller compatible compilers. As a result various kinds of embedded C programming compilers for 8051 microcontrollers are available in the market. Most of them are offered as part of a package along with debugger, simulator & integrated development environment (IDE). The Keil IDE/compiler is one such popular variety. Similarly SDCC (Small Device C Compiler) is a free & popular compiler that is found compatible with Zilog Z80, Motorola 68HC08, Maxim 80DS390 & Intel 8051 microcontrollers. The open source software code of SDCC is distributed under the guidelines of GNU General Public License.

Though pascal language is rarely used in embedded C programming, a few special Pascal compliers are available for the 8051 microcontroller. The Turbo51 & KSC Pascal51 are good examples of commercial Pascal compilers. Turbo51 is a free complier based on fast single pass & advanced multi-pass optimizing technology & using syntax of Borland Turbo Pascal 7.

While there are not enough options in basic or Pascal compilers, the C compilers are available in abundance. Users are facing difficulty in finding good quality basic or Pascal compilers for 8051 programming. The chief function of the compilers is the code they produce which should be optimized well to enhance the speed & size. However it is not the programming language in compilers which decide the size of the program codes for achieving specific tasks in 8051 programming. Either Pascal or C can be used to generate an optimized & compact code. It is the programmers preference on which platform he/she will feel comfortable working in.

Hardware Keylogger – Helping You To Monitor PC Users Without Being Detected

  • Posted on October 23, 2017 at 6:07 pm

Sue has been the most commited employee. She is always at her duty post doing what she was being paid to do. With all the zeal and industry being exhibited by Sue and most of her colleagues, the company couldn’t explain why productivity was taking a steady and speedy decline until a consultant detective was hired.

Investigations revealed that Sue spends 70% of her -work’ sessions in dating chat rooms. Other times, she was emailing her pals and reading internet news – oh she loved the -fashion and style’ segments!

Worse case for Steve who was discovered to be trading the company’s sensitive information’s to a rival group.

How were these discoveries made since these people work alone in their closets and never share their computers?

Hardware keyloggers to the rescue!

keylogger are devices that are used to monitor the activities on a computer. It works by tracking the keystrokes, recording conversations, tracking the creation of documents and monitoring emails. This is usually achieved when a hardware circuit is attached somewhere in between the computer keyboard and the computer. They are designed in such a way that they blend with the rest of the computer cabling.

How they work

They basically interrupt the keystrokes signals and stores them away. The storage can range from 2MB, which is enough for one – week use, and up to 2GB of flash memory. Ideally, these memories can only be accessed by the individual that installed the device.

To access these memories the installer presses a combination of keys which switches the device from a keystroke-capturing mode to a usb flashdrive mode. Then you receive a message which tells you that a new usb disc drive has been located, and there you will find the keystroke logs that were collected. You also see a configuration file which you can modify in order to change the secret access key.

Hardware Keylogger are now preferred to software keyloggers. The latter can be easily detected by software scanners, and their operations are limited to a single computer. They are also dedicated to only one type of operating system which could be Windows, Mac OS, Linux, etc unlike the hardware equivalents which are operating system – independent, and whose operations, recording and playback, can be done on two different computers. One other minus for the software type is that it requires full access to the operating system to be installed, when the installer might only want to sneak it up and catch the target users off guard.

So for parents who want to track their child’s PC activities or employers who want to monitor their workers or generally for computer users who want to back up typed texts, monitor remote computers, retrieve unknown passwords without depending on the operating system, hardware keyloggers provide the perfect answer.

What are the business benefits of NFC mobile phone technology

  • Posted on October 23, 2017 at 3:11 am

Near Field Communications, or NFC, is a new technology with unlimited applications.

NFC uses RFID technology built in to the latest generation of mobile phones to scan or swipe small RFID tags, which can be placed just about anywhere. Tags can be programmed to trigger different actions when they are swiped by phones.

Many businesses or organisations have field based operations that need managing in real time. NFC technology gives these businesses leading edge management capability.

NFC can be used in a diverse array of industries with mobile staff, mobile assets, or multiple sites and locations. Because NFC technology uses readily available NFC enabled mobile phones and inexpensive tags, it can be applied anywhere, and by any type of field personnel.

The key benefits of NFC technology for businesses with a field based operation include:

1. NFC is Easy to Use

Using NFC technology is so simple, it’s accessible to just about anyone.

All that’s needed to run NFC operations in the field are RFID tags which can be situated in key locations, and NFC-enabled mobile phones.

For field operations staff, using Over-C NFC technology is simplicity itself. Just tough a tag with a phone, and that’s it. An automated NFC management system then does the rest, recording the time and location of staff, and sending them any special information or data they may need on their NFC enabled mobile phone.

2. NFC Improves Communication

NFC is an extremely effective way of improving two way communications between managers and their staff in the field.

Whenever a field operative touches an NFC tag with their mobile phone the operational management team receive an instant and verifiable confirmation of the location of field staff. Field staff can benefit from automated reporting, which saves time and improves accuracy.

3. NFC Enables Real Time Management

NFC technology lets businesses operate and respond in real time.

When an NFC tag is touched by a mobile phone, notification is in seconds, so operations managers always know exactly where their field personnel are, and what they are doing.

NFC allows businesses to streamline the way people work at, and report from, remote locations. It also allows field based personnel to focus on what they do best, whilst managers benefit from greater visibility in field operations.

4. NFC Improves Customer Service

NFC technology actively helps businesses to deliver enhanced customer service.

Data reporting by field operations staff becomes faster, more efficient and more accurate.

Field operations managers can use this real time data to generate customer reports and measure results faster than ever before – and faster than their competitors.

In fact, using NFC technology in a business can give it a commercial edge to help it gain and retain high value clients.
