I am trying to establish a serial communication between Labview 8.6 and Arduino Duemilanova board via USB. I read that USB is the same as RS-232 serial communication just that the USB has a built in USB/RS-232 adapter in it. Please correct me if I am wrong. Download mp3 sirine polisi landun. I tried to establish the communication using Labview's Basic Serial Write and Read vi example however it was not successful.

In the String to write box on front panel of labview, do I need to specify a string or a command that is used to program the Arduino board via the Arduino software? Any help will be appreciated. I am new to Labview, so please give as much detail as possible when responding. Code: * Dimmer * by David A. Mellis * * Demonstrates the sending data from the computer to the Arduino board, * in this case to control the brightness of an LED. The data is sent * in individual bytes, each of which ranges from 0 to 255. Arduino * reads these bytes and uses them to set the brightness of the LED.

* * from the labview side, you can use the example icluded in labview distribution labview>>help>>find examples select tab search type 'serial' in keyword field double clicks on serial founded than in le list on the right choose basic serial write and read. Ok now, leave the VISA resource parameter as is, its define the port seting and in this case fit with the setting on arduino side, make a left click on 'string to write' field the select hex display, this permit you to write directly in hex notation, now togle off the switch 'read' we don't need to read nothing back from arduino. Now try to write FF in the 'string to write' field then press RUN button, the white arrow on top left (the single arrow), this should ON at maximum power your led. Mgriebel, Thank you for the code. I was able to look at what you had put together and a similar simple code with the only difference being a method of saving the data. However, I find that I am getting about every other sample returned as a zero or some loss of data as seen in the graph below. It is not constant, and it seems that I loose the samples for a period of time and then there is a reconnection.

Plotting the data straight from the Arduino-15 serial output with Excell produces a perfect sinusoid from my Function Generator, however looking at my labview plot from the same device, I get an intermittent signal, with no change in hardware. Thanks very much for any advice.
