How to print obtained string in read buffer into a table in front end ?

[madara77]

Hi. I want to print the string obtained in read buffer into a table in front end. I am performing serial communication with a machine, where i am supposed to pass a command to get response. The machine which i am trying to communicate has 6 cylinders , when i pass command "b" it sends the values of the cylinders in the form of string. Example : when "b" is passed i get " b 50.8 54.8 60.2 65.3 57.0 61.6 " in read buffer . I want to put these values in a table in front end.Can you please give a hint/ solution to my problem?.I have attatched the vi. Thank you.

Hi Madara77,

Table is an array of stings, first think how you can get the array from the above string,

Here you need to parse the string properly, for the string " b 50.8 54.8 60.2 65.3 57.0 61.6 "

1. Remove first and last space, Remove b , (Use string subset function)

2.Now you have "50.8 54.8 60.2 65.3 57.0 61.6"

3.Now try to get the array from above string Use Spreadsheet String To Array function

    a) use delimeter as space constant.

    b) Array type as string 2D array

Now, just wire this array to table indicator.

hope it helps.

I could get values in the table,but when I get next set of values the previous values are getting replaced in the table .How to update(to the next row) the values in the table as the next set of data arrives.

You should store the table values in a shift register and then use Build Array to add new rows to your table.

Hi. I could get values in the table. The set of values sent by the machine is getting stored in each row. Suppose if i want to flush all data after some 10 set of values and again store next set of values from beginning of the table what should i do?

Assuming you are storing the table in a shift register, you just write an empty array into the shift register and it will be cleared.  If you want it to happen every X iterations, either use the i and a Quotient & Remainder or keep you own counter so that you know when to clear the table.
