ADC read with labview

Post by Hansanaut »

Hi folks,

can anybody help me with this?
How do I read out the adc values of the sub 20 via labview?
Is there an example?

Thanks for the help!

Hi,

The labview sample vi's available under C:\Program Files\SUB-20\sample\.NET\labview folder. To read the ADC samples you should call the ADC_SetConfig and ADC_Single/ADC_Read methods.

Hi,

thanks for the fast reply.
I've already found the examples.
But I still don't know how to configure the input ports of the methods.

What is the input of the adc_read method? How do I configure 'data' and 'mux'?

I attached a screenshot and the VI - maybe you can help me to solve this.

Sorry about the noob questions :-) - I'm not realy used to work with labview that much.

Thank you!
