I have an isp due in 2 days and I have to make 2 seven segment displays. I have to enter a temperature in fahrenheit and it has to be converted into celcius. I have to program number -20 to 20 in celcius for them to be displayed on the 7 segment display
What is the problem you are having?

After thoroughly looking into making a seven segment display I still have no idea what to do. I started to try somthing out and it is not working. It sais unable to find I/O device. I need to know what this means and what I have to include to make it work

Do you have a parallel port on your machine? I don't know if you need drivers for a parallel port, but if so, are they installed?
