1. Introduction The 8051 based single board development system (DB – 51) support 8051 family

microcontroller. The software supplied with this kit is having Assembler and In System

Programmer (ISP). Due to this software assembling and programming Flash program

memory becomes very easy. The user for developing real time projects can use this

mini board as a development platform. User can design, build and test any 8051 based

application / project with the help of this development board quickly.

This system is useful for students, teachers, professionals and hobbyist. Student

can apply his theoretical knowledge to develop some project and test it with the help of

this system. Teacher can set new experiments for students based on 8051

microcontroller interfacing with Keypad (3X4), seven-segment display, LED, Switches,

relay, LCD, RTC, E2PROM, I2C bus and RS232 bus. Teacher can also set experiments

based on timer application (as timer / event counter) and serial communication (data

transfer from kit to PC and PC to kit). The professional can develop, test and debug his

project. Also hobbyist can use this board to design and develop their own applications.

This board (DB-51) is provided with PHILIPS P89v51RD2 microcontroller.

called RIDE.

Using this unique Integrated Development Environment (IDE) you can:

• Create and edit your programs, written in either assembly or C language.

• Run the compilers, linkers and debugger tools.

• Maintaining a dual project “80C51 – XA”, switching at any time from a 51-

derivative to an XA-derivative, with just one click!

3.1.2. RKit51+XA Installations and Invocation

The « RKit51+XA-Installation » program (INSTALL.EXE) installs all the necessary files

and correctly configures the environment for running the interface and the development

tools. Please close all other active application programs prior to installation.

To run the installation program :

3.2. Installing Flash Magic – In-System Programmer (FREE software available on website of Embedded Systems Academy )


3.2.1. About Flash Magic: NXP Semiconductors produce a range of Microcontrollers that feature both on-chip

Flash memory and the ability to be reprogrammed using In-System Programming

technology.

Flash Magic is Windows software from the Embedded Systems Academy that allows

easy access to all the ISP features provided by the devices. These features include:

• Erasing the Flash memory (individual blocks or the whole device)

• Programming the Flash memory

• Modifying the Boot Vector and Status Byte

• Reading Flash memory

• Performing a blank check on a section of Flash memory

• Reading the signature bytes

• Reading and writing the security bits

• Direct load of a new baud rate (high speed communications)

• Sending commands to place device in Boot loader mode

3.2.2. Installation of Flash Magic: To run the installation program:

1. Select SW_8051 --- Flash Magic Setup ----double click

2. Follow the instructions in the installation window.

3. After restarting the computer select Start | Programs | Flash Magic | Flash Magic

3.2.3. Support For support you can visit web sites

7. Serial data transfer via RS 232 port 7.1. Using HyperTerminal: You can run serial data transfer program on DB-51, you can get display on

computer monitor using hyper terminal program. To use hyper terminal program of your

PC steps are as follows:

Click on start >> programs >> accessories >> communications >> hyper

terminal >> new connection >> name XYZ_1 >> connect using COM1

Properties (configure) as follows:

Bits per second = 9600

Data bits = 8

Parity bit = none

Stop bit = 1

Flow control = none

Properties (settings) as follows:

• Window keys

• Ctrl+H

• Simulation VT100

Save the settings

Now you can use hyper terminal program (XYZ_1) to see key no of pressed key on PC

terminal
