    hi all

    i have a homework due to Jan/4/2012 to design a frequency counter as follows:

    1- The design must have a keypad as an input,and a 16x2 LCD as a output.
    2-The input wave could be square,sin wave....
    3- I must use concepts of 8088,8255,8254 in designing the counter
    4-Microcontrollers or ready IC's are not allowed in the design
    5-In the final report i should show the design with comments,flowchart,and the assembly code used to run it.

    I am not too much into microprocessor interface so if anyone can help me it will be great..

    thnx all :)

    8088? Peripheral ICs needed and a 16x2 LCD? :eek:

    Who on earth is setting homework assignments like that? It's not the 1980's anymore!

    (wiki) "The Intel 8088 microprocessor was a variant of the Intel 8086 and was introduced on July 1, 1979."

    Tell your instructor to go and HIS homework before trying to teach people to start their careers learning to use 8088s...

    hehehhe youre right .. but maybe i got that part wrong ... the 8088 and the lcd are okay to be a ready IC ..and i forgot to mention that we should put a bluetooth module of our choice to send the result to any other bluetooth device ..

    I did part of my Microprocessors Lab last semester with an 8085. Time doesn't travel with the same speed everywhere.

    We used a 68hc11. I would have rather used a much newer MCU like an AVR or PIC but we did accomplish some pretty neat things with it throughout the semester.
