interactive execution mode in FPGA

islamabad — Thu, 17 Nov 2011 06:04:20 GMT

hi ,

i have a problem that when in run my fpga vi, then after compilation it start running in interactive execution mode and meanwhile it is running in this mode i cant run my host vi because as soon as i run my host vi there comes an error displaying "Error occured" and the possible reasons are :"labview fpga:the operation could not be performed because fpga is busy n interactive mode.stop all activities on fpga before requesting this operation"

plz help me because i am stucked....

hai friend sometimes this error will occured.... shutdown the icon of FPGA compilation in your tray icon... then close the corresponds content Project Explorer... reopen and compile again...it will work

i have reopened it again and again bt every time i run, the same error is occuring........

by the way thnx a lot for help

if you can do any more then plz let me know

Could you send me your VI which shows Error while Running ,so that i try to rectify that...

you can not have the FPGA running interactively while trying to access it with a host VI.

the host vi is supposed to open a reference, run the VI and programatically interact with the FPGA VI.

hi,

here is my vi which i am trying to run

i want to implement QPSK modulation while using analog input and output.lvproj but what i have seen that my fpga vi is accepting 5000 samples but is unable to transmit any data

moreover still i am having the same problm which i have discussed above

attached is my code..plz have a look at that and help me

islamabad,

I am having trouble opening this project as it requests several subVI's that are missing as well as an NI library. Could you please include these or send a simple VI where you think the problem may be isolated to?

hi, here is complete code i am using...i want to use QPSK modulation on the transmitter and demodulation on the receiver

there is another problem which appears pretty simple but i cant be able to resolve...if u have a look on the constellation diagram in the host vi, the way i am plotting at the transmitter side(dots in red) , i cant be able to plot the same points on exactly same position(dots in white) and the problem which i understand is that "analog input and output" is not processing integers....it is considering all numbers as unsigned, thats why all the points are being plotted in the first quadrant(where both x and y are 1),

plz help me out with these two problems..

islamabad,

Are you using the modulation toolkit for the QPSK modulation or did you produce your own using fundamental VI's?

Also, you may be able to typecast these values to the appropriate values for plotting.

hi,

i am producing my own variables for QPSK modulation.you can see this in the tag given in my last reply.you can also find in host vi the constellation diagram used for plotting

islamabad,

I am not sure you can run the host to FPGA methods while the FPGA is running without throwing an error. I will do some more researching though as to how you can accomplish it.

Can anyone on the board confirm this hypothesis?

Dear officer,

Hi! I have read these messages as I have met the same problem when I try to interface FPGA through C code,and the error-61203 appears.Would you mind if you can give me some instructions on this?

Thanks a lot!

Sincerely,

John

Hello,

Could you explain in more detail which problems you are running into when trying to interface a C API with your FPGA? Unfortunately, I did not see any information about the error, -61203, you mentioned.

Could you also explain what your application is trying to do? Thanks!
