    Just a couple of quick observations of your circuit -
    Your multiplexing of the keypad won't work - there is no way to detect 1, 5 & 9 buttons. With care you can share the keypad verticals or horizontals with the LCDs data lines.

    The LCD module uses D4-D7 in 4 bit mode and D0-D3 should all be grounded.

    The RTD connection doesn't look right either - hard to tell without device specifics, but whole way it is connected to the op-amp, and the way the + & - inputs of the op-amp go to the MSP430 don't look right for a device that is normally resistive.

    energia is very useful for developing code that works well.     but, we still don't know what that project should accomplish.

    I'd be more worried about the fact that you're on a University course that obviously involves microcontrollers and you say you aren't good at programming microcontrollers.
     
    Everyone on here is very helpful and if you're stuck on something specific then it's a great place to get some advice. However, getting other people to do your work isn't really fair. I'd suggest you start with your textbooks. If your project principal isn't very helpful then I'd suggest asking him again. If he's really refusing to teach you then let the university know.
     
    What does everyone else think? Am I being too harsh?

    See my post in projects for an example using ds18B20. Not the most beautiful code, but does the job. The portions that deal with reading/controlling the ds18B20 will hopefully give you some guidance. I DO NOT recommend copying as presented. The types are not ideal, the low level functions should be inlined, and, for a single sensor, things can be streamlined by eliminating the channel bitmask.
     
    I would also question how you connected the keypad. What are the resistors for? With your row and column connections sharing pins, what will happen if you press the '1' key?
     
    If you borrow code or schematics, don't neglect to reference the source clearly. It is for your benefit, so you will know where to go if you need more information later, as well as good moral practice.
