table

[BENIO]

I am quite new in LABVIEW, I am trying to build a table which will be filled with data appended from a chip, in fact I want to read the contain of the hole memory in the chip which contains 80x8 bits data register.The table should contain 4 columns and 80 rows (adress, value in HEX, value in BIN, value in DEC), I dont know how to insert columns which will contains respectively the values in HEX, BIN and DEC?
Thanks a lot for the help.

Hi Benio

The Table just can be filled with string-values. So you have to convert your values into strings, what shouldn't be a problem.
With these converted strings you can build an array and wire it to the table.

For a newbie, this might be a little difficult, especially converting a number into an 8 bit binary string. So here is a vi that does it all.

I've never used Excel with Labview but if you post your code, or the part you are having problems with, someone here may be able to help.

Guys,
Does anybody know how to clear a table after filling it? I have a problem with my program when I am trying to fill my table for a second time with new acquired data the first row value is the the same as the previous value from first acquisition but if I redo a new acquisition it is correct, I suppose that the table values must be reseted to fill it agin with new values?
Any suggestion guys?

Benio,

All you have to do to clear the table programmatically is wire an empty 2D string array into the table terminal (see attached picture). This works because the table is just a 2D string array with some additional meta information, as far as LabVIEW is concerned.

Take care,
John

Hi,

I am new to LabView and am trying to clear out a table for each new acquisition of data. In searching this forum for "clearing a table" I saw Jonner's post to Benio ("re. Table"):

"All you have to do to clear the table programmatically is wire an empty 2D string array into the table terminal (see attached picture). This works because the table is just a 2D string array with some additional meta information, as far as LabVIEW is concerned."

However, that only clears the data shown in the table on the screen. When I get a new run of data, the old data in the table pops back there, and the new data is appended to the bottom of the table.

Does anyone know how to do this? (Even NI tech support was struggling with this.) Thanks.

(Also, I really don't want to loop 1000 times, but could not figure out how to (what property node to use) determine how many cells in the table are populated. The rows and columns properties just returns the number of *visible" rows and columns, not how many are actually in the table. Any ideas? Thanks again.)
