sending data randomly from transmitter

[syanitaa]

hye...

here i got some problem, regarding on sending data..

how can i make the data to be send randomly... which i mean

example...

at first time..i sending assign transmitter A, followed by transmitter B, and then C...

after that.... it send transmitter B, then A, and C..

then....it send C, B and A...

its not follow sequence...it can be any transmitter to send first...

it is i need to used the flat sequence? how to do that?

i donno how to make the transmiiter to send randomly data... it is any alternative?

can u show me...thank you...

Do you want it to be actually random, or do you just want it to use the first transmitter available?

You don't have three separate transmitters. You have a single serial port that you are writing to. You can just randomize the data you are sending.

i run it once, then the transmitter A will send the data first. After that transmitter B sending, and lastly C..

randomly means, not nessasary the transmitter A to send first...It can be transmitter B, or transmitter C..

I don't know how to make it any clearer. You have a single serial port that you are writing to. You have three separate VISA Writes going to the same port. You can only write to that single port one at a time - the three VISA Writes cannot happen at the same time. You could simplify your code and have a single VISA Write. then you could randomize the data.

here..i attach the new file that i did...but have some error...it cannot go to transmitter B

[Dennis_Knutson]

Using floating point numbers for comparisons is problematic and you have made it much too complex. Here's something simpler that you can try. It just randomizes the data as I said earlier and uses a single VISA Write. No need at all for more than one since you only have a single com port.
