    Hello everyone,
    I'm doing a school project on "Temperature Controller using 8085".

    The project requires the Microprocessor to compare the temperature input( given by lm35 interfaced with 0809 and 8255) with a set temperature.

    I am facing difficulties in interfacing 0809 with 8085 using 8255PPI..
    Can anyone please help me with the circuit diagram ( pin connections)..!!

    any help is greatly appreciated..!!

    Google "0809 with 8085 using 8255PPI". There is a document called "Micro 1".
    Figure 3 on page 20 (2-7), is that what you need?

    Hello,

    The link you gave is to a not allowed site over here.
    You can upload the image using the paperclip icon above the edit window.
    The schematics can be attached as .png
