Need help

[kor]

Hi to all,

I have just started to learn Labview 7.1, but i cannot do anything even it being too easy.

Anybody can say me how can i do that?

That is :

writing programme to measure and display the I-V characteristics of a p-n junction diode and to calculate the differential resistance as a function of the applied bias.

and these 4 steps:

· The program should apply current (I) and read voltage (V).

· Reverse bias current values should be negative, forward biases should be positive.

· Minimum and maximum current values for both forward and reverse biases should be entered from the front panel.

· The voltage limit value should be entered from the front panel. (The default value is 5 V).

I know these are so easy, and please help me little.

Thank you to who can help me.

Sounds like you'll need three numeric controls for input and one numeric indicator for output. You can drop these from the Controls > Numeric palette on the front panel. Most of the nodes you'll need to code your calculation will be on the Functions > Numeric palette on the block diagram. Take a stab at it and post back what you come up with.

Have a look at the In Range and Coerce Function (Comparison Functions Palette) for your limits, I found it handy for seting limits.

but then I'm using 2009, hope it's in your version!
