I received a M202SD08GR VFD and I'm trying to hook it up to the Bus Pirate. I have 5 wires coming into it, 2 of which are AC 6V that go through a rectifier and regulator. I'm trying to figure out how to hook the other three wires to the Bus Pirate. One of them in labeled RXD which I assume is Receive. I hooked this up to MISO MOSI on the Pirate. The other two were ground and +5 which I also hooked up the the Pirate. I've connected it in UART mode, set the Rate and parity as it says, but when I send anything to it like 0x14 to turn the cursor off, nothing happens.
Any help would be great. Not even sure if what I'm trying to do is possible.
