    We have no idea of the display you are using. Could it be as simple as adding a LED minus sign?

    You might also be interested in the fact that the DC1820 is no longer available. If this project has some future application in mind, finding a substitute for the DC1820 would be a good idea.

    Have you tried the PIC16f84?
