I’ve been assign to make a project of two 2×2 matrix operation circuit i.e addition,subtraction,multiplication,inverse,determinant & adjoint using 8051 microcontroller,but I am aunable to find its circuit.Can anyone plz help me out.Waiting for reply

[dagakshay]

what will you use to send the i/p and display the o/p in your circuit… its a very uniqe type of project.. nice one…

I can use keypad for input as in casio calculator for matrix mode that shows its output on LCD.Now anyone can help me in its circuit coz I dont know what to attach exclusive of 8051,keypad & lcd

hi ..I think your system needs only keypad and lcd.

you can use 4×4 matrix keypad. and i think 16×2 LCD is enough for mentioned operations.

 

You can get ckt for interfacing of 89c51  with lcd and keypad here itself in EG in LABS  tab.

Coding of interfacing is also available here itself. Follow the link below

Your main aim should be your logic for your application and that will be very interesting.

But its a circuit of electronic code lock

arithmatic operations will be purly algorithum part… first i think you should start interfacing LCD and keypad as you don’t know that part…

here i am sending you the LCD and keypad interfaicng tutorial links….

 

LCD

Keypad

as soon you cover these let know your algo we try to create a good algo first then we will go for the code…

 

and Kaubstubh has post that link since it is a combination of LCD and keypad interfaicng with 8051…..

hi all.

 

i am also interested in this project.

whaty i am trying is i save two variable and multi ply them, save the value in third variable.

but the problem is controller multiply them in Binary and thats y i am getting wrong values.

 

before sending the result to LCD , i must convet it to ASCII.

bt i dnt have any idea abt that.

 

can anyone help me in this.
