Free Development Toolchain for 8051
SDCC, Eclipse for 8051 microcontroller
Last Edited: Sep-2008
This is Free Development toolchain based on SDCC compiler and Eclipse IDE. SDCC is Small Device C Compiler , which support 8051 microcontroller. This is opensource and free to download. On the other hand eclipse is open source IDE, This IDE is now a days used by many vendors and users. We have plugin for SDCC for eclipse.
So by using these two we can preare a development toolchain for 8051. To know more read complete article here. [ ... ]
Interrupt Programming for 8051
Learn to use external interrupt practically
Last Edited: Sep-2008
Interrupt is one of the most inportant part of Embedded System programming. It is quite tactic and easy to program once learned. Here we will tell you how to use external interrupt with a practical example. In the example we have inerfaced stepper motor with 8051microcontroller and a switch is used to connect with interrupt line.

Complete working program is also given. [ ... ]
8051 Programming: Interfacing LCD in 4 bit mode
Lcd in 4 bit mode
Last Edited: Jul-2008
Interfacing of LCD require 8 data lines (D7 to D0) and 3 control lines (RS,RW,EN). For that we microcontrollerís 11 lines are engaged. In case of using 8051 microcontroller we most of the times we can not effort this in commercial applications. because we require more I/O lines.

So, it is possible to interface LCD by only 4 data lines. In that case we require only 7 lines of microcontroller to interface with LCD Display. Read this article to know how to do that. [ ... ]
8051 Programming: Interfacing via Serial Port
Debugging technique for 8051
Last Edited: Jul-2008
Embedded System development is not an easy task. Major problem is that we do need to see value of variable of our program and information about flow of our program. For this requirement people use In Circuit Emulator ( Click Here ) which is costly tool. And without knowing actually what happening inside microcontroller, it is very difficult to do debugging.  [ ... ]
Interfacing 16x1 LCD with 8051
Learn how to interface and program 16x1 LCD display with 8051 and
Interface LCD with microcontroller, code for lcd, 16x1 LCD Displayr - Keywords
Now a Days, LCD or Liquid Crystal Display are very common for Displaying Alphanumeric characters.The Working of 16 x 1 LCD is Little Bit Different then of LCD 16 x 2. In Most of Cases 16 x 1  LCD is available without Auxiliary Controller. Means as you see only HD44780 Controller at Back Side. In this section we discuss LCD 16 x 1 with no Auxiliary Controller.

This article will guide you how to write code for 16x1 LCD display. In same way any microcontroller can be interfaced with 16x1 LCD display. [ ... ]

Interfacing with 8051 microcontroller
Last Edited: June-2008
The Stepper Motor is easily interfaced with 8051 and ULN 2803.Darlinton pair with high current rating. User can make Driver Circuit with help of Transistor. But ICís ULN 2803 is best method for ease of design. User can use Pull up and Pull down for enhancing or decaying the value of current. [ ... ]
Real Time Operating System (RTOS), are used in Embedded System. Now days there are so many vendors in the market which provide RTOS. Some of them are well established also. We try to compile a list of RTOS which are available in market as per our knowledge. This list of RTOS is divided into two categories, Free or Open Source RTOS and Proprietary or Closed Source RTOS. Below is the complete list of RTOS  [ Ö ]
