    Re: Can anyone advise using 89c2051 to build a count-up coun

    hi landrover,
    you could use one 8 bit port of the 2051 to connect to the pins of the seven segment display. Use three pins of the other port to select the 3 displays. Now your program should do this:
    enable display 1. Send corr. digit to port one(connected to 7 seg).
    enable display 2. Send corr. digit to port one(connected to 7 seg).
    enable display 3. Send corr. digit to port one(connected to 7 seg).
    do this quickly. prabably at 1-10khz so that the flickering would not actually be noticeable.
    best of luck,
    bye
