LabVIEW
1D Boolean Array to 1D Integer Array conversion for FPGA FIFO
Hello, I am using a PXI7813R card. I would like to pass some data between the target (FPGA) vi and the host vi using the FIFO. I have a FIFO setup to 1023 "32 bit integer" samples. I have a boolean array of 32000 samples which would be the same as 1000 32 bit integers, that I acquired using the PXI7813R card. I would like to convert the 1D boolean array to a 1D "32 bit intger" array. This seems like a more a difficult problem than I first thought as the labview functions are reduced when targetting a FPGA device. I have attached a jpg of how I would like to do it. I am getting a "Arrays must be fixed size in current target" error for the output from the array subset function. I know this is because one of the inputs is not exactly a constant, i.e. the index input for array subset, but regardless of the index, I will only ever be taking 32 bits from the boolean array at any time to convert to a 32 bit integer to then place in the FIFO. Any suggestions of how I may get around this problem would be gratefully recieved. Regards, Michael.
