Read ADC from KNOZZ

[cowleym]

Hi

I am a new to the Dynomotion kit and so far am very pleased. Using LabVIEW and.net I have created a trajectory planner, coordinated motion from dxf files, along with buffer control and process flags.
So far so good.
I now want to look at implementing plasma arc voltage control and have purchased a Knozz board for the analog input functions.
I would like to put these values in the persist array so I can read them using GetPersist and do stuff with Labview.
I have looked at the KnozzControlTemps programme and can see that it almost does what I want, but am struggling with defining the analog values and writing to the persist array.
Could you give me some guidance please as I have no knowledge of C .

Many thanks


Mike

Hi Mike,

I have looked at the KnozzControlTemps programme and can see that it almost does what I want, but am struggling with defining the analog values and writing to the persist array.

After reading the bed ADC reading via SPI into raw_counts_bed you could then place the integer ADC reading into persist variable 150 with:

persist.UserData[150] = raw_counts_bed;

Hi

that works very well thank you.

Thanks again for the quick response.
