Hey I have a VFD Display here that can use Parallel or Serial Connections, I have the data sheets but they dont name the pins the same as Industry standard.
  1. D7
  2. D6
  3. D5
  4. D4
  5. D3
  6. D2
  7. D1
  8. D0
  9. /WR
  10. A0
  11. /CS
  12. T (0)
  13. Busy
  14. /BL
  15. Serial In
now I hooked up my D4-7, RS to #9, Grounded #10, E to #12.
I have scrolling random characters/symbols,

swapping #12 and #9 does not change anything, still scrolling.

removeing ground from #10 removes all scrolling stuff and flashes curser like a ghost image randomly on screen.

unplugging 9 or 12 stops scrolling but does not update screen

I am unsure of what some of these pins are. If someone can tell me what pins go to the E and RS, and anything that needs grounding... I might be able to test this display. I am not able to test the Serial in right now as I still have to learn serial out's first. But would like to use this as a test Display since it does either format.
