DPIMREF Instability

Discussion in 'VHDL' started by dutchgoldtony, Mar 13, 2005.

  1. Hi,
    just wondering if anybody here has worked with dpimref from Digilent
    https://www.digilentinc.com/Data/VHDLSource/EPP_Parallel/DpimRef.pdf?
    I'm using it in a design at the moment but I'm starting to notice that
    after anything from 2 to 20 passes communications between the board
    (I'm using a USB module)and the PC break down and the FPGA needs to be
    reprogrammed. From debugging, it's the DPCPutReg function that fails.
    This is starting to kill my design and my project, not the best of
    things considering it's my final year project!!!

    Thanks for any help you can give,

    Tony
