Now you can burn microcontrollers in your home with less cost of making AT89S51 series microcontroller burning IC kit. AT89Sxx series IC’s have inbuilt ISP (In System Programming) module so we can burning microcontroller easily. Here is the simple board circuit for making of AT89Sxx series kit for burning hex file into on-chip. Continue Reading…

It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips.

But times have changed. Digikey lists over 16000 different line items under a ‘microcontroller’ search. Which one should a hobbyist with no particular prior experience choose? Continue Reading…

Tools you need for writing 8051 micro controller:

Here are the some of tools used for 8051 microcontroller programming and simulation

  • A51-Assembler
  • Code editor -Syntax highlighting Notepad.
  • Simulator-windows based Smart n Small Simulator.
  • Baud -Timer value calculators for various baud rates.
  • C compiler for 8051.
  • RIDE software – simulation Click here
  • Keil uVision – 8051/ARM simulation Click here (most preferred)
  • Proteus – Fully embedded simulation software  Click here

Most projects you create with the 8051 microcontroller require some form of  display.  The most common way to accomplish this is with the LCD  (Liquid Crystal Display).  LCDs have become a cheap and easy way to get text display for an embedded system Common displays are set up as 16 to 20 characters by 1 to 4 lines.

For the seven segment display you can use the LT-541 or LSD5061-11 chip. Each of the segments of the display is connected to a pin on the 8051 (the schematic shows how to do this). In order to light up a segment on the the pin must be set to 0V. To turn a segment off the corresponding pin must be set to 5V. This is simply done by setting the pins on the 8051 to ‘1’ or ‘0’.
