no image available Using Easy-Downloader with Unsorted HEX Files

Some compiler generates an unsorted HEX file, i.e. the hex code of the main( ) function put before startup and some interrupt code. The current EZ3 makes the number of byte to be sent to the programmer board less than the actual byte. Kurnia Wijaya, my friend lives in Jakarta Indonesia sent me the Window version hex file sorter. I have tested with code produce by some compiler, it`s work very nice...

no image available @Line Following Auto Robot

This Project Line Following Autonomous Robot is based on 8 bit Microcontroller AT89C2051. This Robot follows the black line which is drawn over the white surface or it follows the white line which is drawn over the black surface. The infrared sensors are used to sense the line. When the infrared signal falls on the white surface, it gets reflected and if it falls on the black surface, it is not reflected this principle is used to scan the Lines for the Robot...

no image available @8051SBC V1.0

I decided to rename C52EVB to be 8051SBC. Since the cpu can be any 8051 compatible chips with 40-pin DIP package. The old day chips, say 8031, 8751, 8032 or the new chips, 89C51, 89C52, 89C51RD2 can be used without any problem. Some may think that your old chips were useless, now you can use it for many projects. The monitor program of new 8051SBC was placed at external 32kB EPROM. With this space, you can customize your own monitor code or even add the application program.....

no image available Connecting MiniLOGGER with Easy-Server V0.9

The Easy-Server V0.9 run on Windows 95,98,NT provides a simple means to connect the MiniLOGGER from anywhere using Telnet terminal. As shown above we may extend the serial cord with 20mA current loop or 75176 driver for RS485 standard. However, with a 9600 baud, the length would be suitable for connecting the MiniLOGGER to the nearest PC having IP address. Now with the Easy-Server that run on Windows 95, 98, NT, we then can extend the length of serial transmission very.....

no image available @A serial to parallel converter using the AT89C2051

The example program included with the PG2051 evaluation kit is a basic serial to parallel converter written in 8051 assembler. This is probably a good example of the uses to which an AT89C2051 can be put - it would be hard to get a serial to parallel converter much simpler than the single 20 pin IC in this circuit. The program is meant to serve as a useful example of 8051 serial routines and other programming, whether or not you actually need a serial to parallel converter...
