i want to use example for read from serial port ,

but i need known what is the condition for correct reading(from 8051 serial port comm)

sorry for being late ya Kimo i didn't see your topic

Well Kimo Let me help you in using serial Port

To have a correct reading from your 8051 Serial port you have to do the following

1- read carefully the pin-configuration file of your serial Port to know which pins are used for Transmission and which for receiption

also to know the flow control and other features in the example you want to Use.

2- serial Port is an asynchronous Transmission this mean's that there's no clock thus you have to Specify the start Bit and stop bit

to ensure synchronizm between Transmitter and receiver. you have to adjust the rate of transmission (which is called Baud rate)

in both transmitter and receiver -- two sides connected to the serial Cable --

3- during transmission error may be introduced in digital data transmitted through the Channel. and that's why we use the parity

to detect One bit error.

4- 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. ...

OR---> Generally loopback test is to Short the transmission Pin with Receiption Pin whatever the serial Port you are using.

to perform loopback test Check this link http://www.pjrc.com/tech/8051/board5/loopback.html''>http://www.pjrc.com/tech/8051/board5/loopback.html' target="_blank">http://www.pjrc.com/tech/8051/board5/loopback.html

Hope i could help you ... if you have any problem feel free to ask ...

Hi Sherif,

The "Singnalverlaufsdiagramm" is a German word for a Waveform chart,Just like any waveform chart .

In your code I saw where you Bundle the cosine and sin wave together so I said it will be fine to dispaly them,that is why I used the Waveform chart to dispaly the signals.

Hope this is clear.

Thank you ohiofudu i'm sorry i don't know German it's Clear Now :thumbup:

for you ohiofudu i want to ask you wt does the 'Signalverlaufsdiagramm' displays ?!

Thank you so much

Hello Steilein

Let me guide you ...

You may start by searching on your LabView Examples i think there is an example about the Parallel port. it's a good Start for you then you can go to NI site and search for more pluse you can [ try a forum search, wander through the LabVIEW wiki and LAVA Code Repository] as crelf told you & and we are all ready to help you if any problem faces you in writing your code.

Welcome to LAVA Steilein ... have a Nice time.

lol

Canadianians ... what about meeting the Americanicans

well ohiofudu the picture is inserted successfully but the problem is when it became transperent . when it becomes transperent you can see the needle scanning the circles but you can't see the Moving targets i don't know why ....??!!

but all i know is that the targets are more important than the needle .

Anyway the soln. i used is applicable and so simple as you can draw the screen with all details you want evenif you insert a pic. form file into office then edit it and control the transperency Percentage then copy the final PIC. and Paste it inside you front panel.

But for sure if you have any other solutions or ideas ... please share them with us so that we can all benefit.

QUOTE(crelf @ Jun 15 2007, 04:30 PM)

Can you please post your solution so we can all benefit from it?

Sure with Pleasure ...

OK thank you all .. The problem is solved now ... i tried [creat mask.vi] you told me about BEN thank you, but finally i made it by drawing the Radar screen in Office with all details required and then copy and paste my drawing inside LabView front panel directly, after then you are able to scale it to fit the area required to be covered. this Method is too fast and simple ... you can also change the appearence of your knobs and sliders or whatever you want ... hope this can help anyone ....

Also, have a look at http://forums.ni.com/ni/board/message?board.id=170&message.id=231915' target="_blank">this. You can import a transparent image into a control.

what a nice Link ... Yen thank you very much

Have you tried the "Create Mask.vi"?

Ben

Never tried it Before, i'll try it now

Thank you for directing me.

OK Thang Nguyen Listen on LABVIEW front panel on the waveform chart you want to specify it's XAxis do the following:

-------------------------------------------------------------------------------------------------------------

1- right click on the waveform.

2- choose PROPERTIES.

3- on the window go to SCALE menu.

4- remove autoscale choise box and then specify the Minimum and the maximum.

5- Press OK.

That's all hope it work as you need isa.

OK ohiofudu thank you but i want to add the pic. to use it in the radar screen. not just to display it so i need to make it transperent to the green circle.

you know that i already made a target on the screen so to detect it we have to specify it's angle and distance [polar representation] ... as you can see in my code the green circle provides the angle in radians and in degree so what about the Range (distance) ... that's why i want to add pic. or even grid to specify the range of the target.

Anyway thank you for your efforts ... but still no solution to my problem so if can anyone help i'd be greatfull

Thank you all

Thank you osvaldo for your fast response.

and for you ohiofudu for the time you spent. but i want to ask you wt does the 'Signalverlaufsdiagramm' displays ?!

another Question ....

After inserting the Pic. successfully How can i make it transperent infront of the green circle OR Vice versa ?

Or do you know how can i add grids and scales for raduis and distance on this green circle

Thank you so much

Hello everybody

I'm building a radar Screen using LabView 8.0 all i could do till now is to do a green circle with centered needle scanning i need now to add a picture as a Background to this circle in order to have more realistic view.

I tried to insert a picture using (READ JPEG file.vi) but each time i do run for my project it asks me to specify the location of the pic. and when i specify where nothing shows up and simulation not completed. i don't know where's the problem.

i need to insert a radar screen Pic. in front of the green circle and make it transperent.

if anyone could tell me how or do it for me , i'd be greatful

Here's the file taking Sample Period 0.01 with any RPM (Revolution per minuite) you want.

Thanks in advance.

Hi everybody,

I'm totally new to this forum, and i'm so glad i finally found such a place where i can share and discuss my problems with the software. I'm relatively new to LabView, i started using it for my graduation project at the begining of the year, and i'm totally impressed.

I'm doing data acquisition and control system design, and it's going well so far. Obviously i'll be a bugging the forums searching for solutions to my (many) problems, so i hope u guys don't get fed up so fast.

c u soon, bye...

Yes Event structure isn't included in Lv 6.0

also i remember that Express VIs helped me alot when i started Using Lab View

You may Order a LabView 8.2 Evaluation Version from the internet For free all you have to do is to Go to

ational Instrumentation then enter labview zone and order your CD.

As a good start you may check the Following Getting started In labiew

for a good reference Check This LabView Student Edition

Hope i could help you

if you need more just tell me
