Hi,

May i know how the LabView8.2 can be interface with uC via RS232?

I had tried this "Advanced Serial Write and Read.vi" LabView itself sample.
When i run this sample, it will comeout a message illustrate the error:
"Error-1073807202 occurred at Property Node in VISA Configure Serial Port (Instr).vi->Advanced Serial Write and Read.vi...."

I tried to remove the Sample Error Handler.vi from the sample then error message wouldn't appear again. Do you know why?

then i try to interface with my uC but still can't interface.

Please anyone can help me?

Thank you.

did u try checking the loopback ??
Connect the serial port to your device. If no device is available, perform a loopback test by doing one of the following. Short pins 2 and 3 on a RS-232 cable or short pin 4 to pin 8 and pin 5 to pin 9 on a RS-485/422 cable.
:-)
 Help like this.

As this is graphical programming (in block form), it will give developer a easy understanding of programming.
Ex:

Ya, you are rite but why don't we directly use that software and it save our time. This programming had their own advantage and usefulness. :-)
What so attracted by me is their Front Panel and it can draw and plot any graph type and waveform you like easiest.;)



Please anyone can help me serial interface part? :-(

Thank You.

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
