hi, i have to sense a x-y co-ordinates from a touch screen and send them to the PC. Do anyone have some idea about how a real-time co-ordinates can be generated on a just like a small screen(area) in labview. such that the small screen (area) in labview gives the sensed co-ordinates showing some kind of indication. and most specially it allows me in (real-time) to generate output from PC vice versa. such that if i draw something on the screen (area) within labview it generates the co-ordinates for the output. thanks.... any tutorial any supportive material regarding it....please post

Thanks olivierL After shortng the TXD and RxD of serial cable the labview prompts as: Error -1073807252 occurred at VISA Read in Untitled 2.vi Possible reason(s): VISA: (Hex 0xBFFF006C) An overrun error occurred during transfer. A character was not read from the hardware before the next character arrived. and i cant read any thing, no appearance on guage. please tell me how ths error can be removed. Whats the mistake?????? the serial cable is fine because i have checked it using hyperterminal so the fault is in coding .....

Hi .. I want to use VISA for READ and WRITE purposes. The data I want to WRITE is the reference point for the position control system using dc motor and the data that pc READS by VISA is the feedback taken from motor. This feedback gives the position which I want to show in labview on GUAGE. I'm just a beginner with labview. I already maked one program but it doesn't works. I checked it by shorting the RXD and TXD of serial cable. If any one can help me please correct the given programming. I'll be very thankful to you. Also please highlight your steps.
