How to read data in serial monitor of arduino in labveiw continuously

Hello everyone,
I have attached the .vi to read the data from arduino serial monitor in labview continuously. I have to monitor the temp. of rtd on labview. but it shows only one value that its read at first and wont get other values continuously. please help me
thank you.

Don't use "bytes at port" set a larger byte count than you expect to be read and enable termination character in your visa serial setup and make sure the terminiation character matches what your arduino is sending.
You might also have to change your Arduino code to place the termination character at the end of each line.

Problem while reading data from Serial Port

Hi All,
I am facing some problem while reading data from Serial Port.
As per the requirement I am writing the data on Serial Port and waiting for response of that data.
Notification for data availabilty is checked with method public void serialEvent(SerialPortEvent event) of javax.comm.SerialPortEventListener.
When we are writing data on the port one thread i.e. "main" thread is generated and when data availability event occures another thread "Win32SerialPort Notification thread" is generated. This creates problem for me as we can't control thread processing.
So can anybody pls explain me how to overcome this problem?
Regards,
Neha

My Problem is:-
I am simoultaneouly wrting data on port & reading data from port.
First I write data on port using outputStream.write() method. Now when target side sends me response back for the request on serial port DATA_AVAILABLE of SerialPortEventListner event occured,we are reading data from serial port.Now till the time we didn't get the response from target next command can't be written on the serial port. When we are writing data on port main thread is executed.Now my problem starts when DATA_AVAILABLE event occured.At this point another thread is created.Due to this my program writes data of next command without reading response of previous command.To solve this prob. I have used wait() & notify() methods as follows.But again due to this my pc hangs after execution of 2 commands. (PC hang in while loop in a code provided below.)
From SOPs I could figure it out that after 2 commands we are not able to write data on serial port so DATA_AVAILABLE event doesn't occure n pro. goes in wait state.
Can anybody help me to solve this issue.
Neha.
Code:
public void serialEvent(SerialPortEvent event)
          switch (event.getEventType())
               case SerialPortEvent.BI:
               case SerialPortEvent.OE:

how to read data.....and move it to internal table....
the requirement is as:
<b>Get the Participant details in an internal table IT_FINAL_PAR</b>
     Loop through IT_PA0002 and move Personnel number (PERNR), Personnel ID Number (PERID), Last name (NACHN), First name (VORNA), Gender Key (GESCH), Date of Birth (GBDAT) into a final internal table for Participant data IT_FINAL_PAR.
      Read the internal table IT_PA0006 to get the corresponding House Number and Street

Hi,
you could try the following:

How to read data from an internal table into a real table?

Hello experts,
I'm relatively new to ABAP and I'm trying to figure out how to read data from an internal table into a table that I created. I'm trying to use the RRW3_GET_QUERY_VIEW_DATA function module to read data from a multiprovider. I'm trying to read data from the e_cell_data and e_axis_data tables into a table that I've already created. Please see code below.
TABLES MULTITAB.
DATA:
query_name TYPE RSZCOMPID,
s_cubename TYPE RSINFOPROV,
t_cell_data TYPE RRWS_T_CELL,
t_axis_data TYPE RRWS_THX_AXIS_DATA,
t_axis_info TYPE RRWS_THX_AXIS_INFO,
wa_t_cell_data like line of t_cell_data,
wa_t_axis_data like line of t_axis_data,
w_corp_tab like line of t_cell_data.
s_cubename = 'CORP_MPO1'.
query_name = 'Z_corp_test'.
    CALL FUNCTION 'RRW3_GET_QUERY_VIEW_DATA'
       EXPORTING
         i_infoprovider           = s_cubename
         i_query                  = query_name
        i_t_parameter            = query_string_tab
       IMPORTING
         e_cell_data              = t_cell_data
         e_axis_data              = t_axis_data
         e_axis_info              = t_axis_info.
If anyone has any information to help me, I would greatly appreciate it. Thanks.

Hi,
<li>Once you call the function module RRW3_GET_QUERY_VIEW_DATA, lets say data is available in the corresponding tables e_cell_data e_axis_data which you have mentioned.
<li>Modify your internal table defined for other purpose, with data from e_cell_data e_axis_data like below.
LOOP AT t_cell_data INTO wa_t_cell_data.
"Get the required data from t_cell_data.
MOVE-CORRESPONDING wa_t_cell_data TO it_ur_tab.
"Modify your internal table wih data
MODIFY it_ur_tab TRANSPORTING <field1> <field2> <field3>.
ENDLOOP.
LOOP AT t_axis_data INTO wa_t_axis_data.
"Get the required data from t_cell_data.
MOVE-CORRESPONDING wa_t_axis_data TO it_ur_tab.
"Modify your internal table wih data
MODIFY it_ur_tab TRANSPORTING <field1> <field2> <field3>.
ENDLOOP.

Problem in reading data from serial port continuously- application hangs after sometimes

I need to read data from two COM port and order of data appearance from COM port is not fixed.
I have used small timeout and reading data in while loop continously . If my application is steady for sometime it gets hangs and afterwards it doesnt receive any data again.
Then I need to restart my application again to make it work.
I am attaching VI. Let me know any issue.
Kudos are always welcome if you got solution to some extent.
I need my difficulties because they are necessary to enjoy my success.

What do you mean, "not fixed?" If there is no termination character, no start/stop character(s) or even a consistent data length, then how can you really be sure when the data starts and stops?
I probably misunderstood you though. Assuming the last case is not ture - there is a certain length to the data - then you should use the bytes at port, like in the otherwise disastrous serial port read example. In this case, it's NOT disastrous. You have to make sure that you read all the data that came through. Right now you have no idea how much data you just read. Also, if this is streaming data, you might want to break it out into a producer/consumer design pattern.
Not fixed means order is not fixed, data from any com port can come anytime. lenght is fixed, one com port have 14 byte and other 8 byte fixed..
Reading data is not an issue for me as it works nice but I have a query that why my application hangs after sometime and stops reading data from COM PORT.
Kudos are always welcome if you got solution to some extent.

How to send data using serial Communication

I want to make serial communication using RXTXcomm.jar file.I was written the code.From this I got the list of serial ports avilable on pc but then after when I was tring to send command to machine which is attached to port it didn't gave any reply.
Tell me that how to send command to port?

This is how I do it:// open port, get ownership
SerialPort serialPort= (SerialPort)portId.open(APPLICATIONNAME, timeout);
// no framing and no threshold
serialPort.disableReceiveFraming();
serialPort.disableReceiveThreshold();
// communication speed, parity, stopbits and databits
serialPort.setSerialPortParams(BAUDRATE, SerialPort.DATABITS_8,
SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);
// no handshaking or other flow control
serialPort.setFlowControlMode(SerialPort.FLOWCONTROL_NONE);
// timer on any read of the serial port
serialPort.enableReceiveTimeout(TIMEOUT);
// open streams for reading and writing
InputStream is= serialPort.getInputStream();
OutputStream os= serialPort.getOutputStream();... then you use the 'os' stream for writing and the 'is' stream for reading.
kind regards,
Jos
