Problem using FIFO together with memory read/write on FPGA 8.0

[kvzhang]

I cannot compile the attached FPGA vi when I try to use FIFO together with memory write. It works if I remove either FIFO or memory write. The compile error message is also attached. Can anyone help me to take a look? Thanks.

You cannot compile a VI with just a memory write or just a memory read function.  You must have both the memory write and memory read functions in order to compile.  Also based on the code snippet you posted I should be clear that the FIFO and the Built in Memory functions will actually use separate memory spaces.  So writing to memory using the write memory function will not make that data available to the FIFO read.  You must use FIFO write and FIFO read together and memory write and memory read together.
