回复： Embedded 16-bit Microcontroller on LabVIEW FPGA

[emailjhd]

Q1:As is shown in the picture below,how can I change the range -32768~32767 to -10~10 ? Please provide me with detailed solutions,thanks a lot !

Question2:As is shown in the program below,how can I set the parameters of sine wave and square wave so that I can see both of the two signals in the scope at the same time.

Hi emailjhd,

Q1: Set a integer word length of 4 bits to get a range of ±15. Why do you need this when your AO needs to get 16bit integer values?

Q2: They are running in parallel right now…

Q1：I want to measure the voltage ranging from -10v~10v，not -15~15.May you help me?

Q2:I can't see both of the two signals at the same time in one signal even though I've tried many times.However,I can only see one signal if I change the labview program.

Your ADCs will deliver values in the range of +-16368.  If you need to scale these to +- 10V then you need to divide these numbers by 1636.8.

The values returned from the node you are using are not physical units, they are binary representations of the output of the ADC.

Hi emailjhd,

How do you want to "see two signals in one signal"???

even though I've tried many times.

What have you tried (many times)?

However,I can only see one signal if I change the labview program.

How did you change your program? Which signal do you see then?

Hi, Intaris,

        Thanks for your reply! I know what you mean.My teacher asked me to change the values -32768~32767 to -10~10V in the picture as follows,so I believe there exists solutions to my problem.If convenient,please provide me with program.

       Best wishes

Hi emailjhd,

please don't spam me with private messages!

Post your questions here in the forum!

(It would also help to attach your VI as we cannot debug images with LabVIEW!)

Hi GerdW,

        I am a new one here and feel sorry to disturb you.

Have you looked at the "Data Entry" tab?
