Hello, I just aquired a few VFD displays.ˇ Theyˇuse a parallel interface.ˇ I am wondering if I can control this with the BS2.ˇ Here is the pinout:ˇ (these are supposed to be similar to a 2X20 lcd, but it glows)
PIN NO. FUNCTION
J1-1 BUSY
J1-2 WRITE STROBE
J1-3 D7 (MSB)
J1-4 D6
J1-5 D5
J1-6 D4
J1-7 D3
J1-8 D2
J1-9 D1
J1-10 D0 (LSB)
J1-11 +5V @ 370mA (TYP) *
J1-12 GROUND (COMMON)
J1-13 NOT USED
J1-14 RESET

I was wondering what pins should connect where.ˇ Also, if anyone can give me any hints on some code to talk to it, i would be very thankful.ˇ I have attached a pdf file with the complete specs sent from the manufacturer.ˇ I obtained a few of these displays for free, and they are really nice looking.ˇ
Obviously, I am new at working with the BS2, but from the small projects that I have messed with, WOW just too cool!
Thanks so much,
John Gjonola

Well i have figured out how to do it.ˇ Attached is the code so that anyone who wants to control a IEE VFD display can do so.ˇ It is really pretty simple, by the way.ˇ The big problem is that you must use an 8 bit interface.
