Hi,
I'm trying to write data to the FPGA memory block from the host pc, since FPGA vi needs to read the same data repeately in the single cycle timed loop when the condition is met.
I understand that I need to write the data to the FPGA target FIFO using DMA FIFO, read the data from the fpga FIFO and write this data to the FPGA block memory.
But it does not work, and I don't know why.
Could anyone post a simple example on this ?
Thanks a lot,
Chang

There are many examples included with LabVIEW, search the Example Finder for DMA.
If none of those help you, post your code (the entire project including all VIs, in a ZIP archive) and explain exactly what doesn't work. Is there an error message, bad data, no data? "Doesn't work" is not specific enough.
