I need to capture a bitstream into a buffer, and I was happy to find a shift register component that should have made this a 1-hour task. 24 hours later I'm still scratching my head. The interrupt output does not seem to work. and the DMA Wizard does not recognize the shift register component as a source.

   

The attached project illustrates the problems. Am I missing something, or are these a bugs?

Two notes: Set the isr1 and 2 to "Rising Edge", "derived" is used for FF blocks.

   

You should issue a isr_ClearPending() in the interrupt handler (in case it gets stuck)

   

 

   

The issue with the wizard is known, will probably corrected soon.
