Thank you for sharing your work on the VFD display especially the data sheet! Serial hookup could not be simpler and here’s my test sketch for Arduino which I’m sure you can port to almost anything. I’d have done it in SPIN but I’ve never used it before… hehe.

Thanks again,
Hank

//code start
// Written in Arduino 1.01
// Tested with Arduino UNO R2 and Arduino Pro 5v/16Mhz

#include

SoftwareSerial VFD(10, 11); // I used Pin 10 for Serial Data
// Pin 1 on the VFD connect to Pin 10 on Arduino
// Pin 2 on the VFD connect to GND
// Pin 1 on VFD power connector to 5V

void setup() {

VFD.begin(1200);
VFD.write((byte)0x0A); //Clear text
VFD.write((byte)0x1B); //Put cursor at
VFD.write((byte)0×00); //Position 0

VFD.print(“Hello World”);
}

void loop() {
// Your code goes here!
}
//code end

I jotted down some details and uploaded a quick vid clip on my blog.

I will add a regulator to the next version. Mind if I tweet your robot?

Wasn’t sure if feeding something > 5V would be a problem. So just + to TP1 and – to TP3?

So I made a little bluetooth tank with one, and am working on some lego robots with my son with another. It’s funny you mention adding a regulator to the board, since that’s exactly what I did. Since I didn’t need any logic level voltages off the board, I just used a through hole UA78M33CKCSE3 and stuck it in the LOGIC_V spot, wrapping one leg around the board and connecting to the VIN+.

Oh yeah, and I used your UART code to talk to my bluetooth module. Works great, so thanks again!

Care to share what you built with it? If you need more boards I can send you some.

To power the Launchpad off of anything more then 3.3V you have to go through the on board regulators that are used for when it is USB powered. There are 2 Test Points (TP) near the USB port. One is the +5V and the other is ground. I pipe the power into the +5V TP. Care is needed however as having the battery turned on and plugging in the USB would be a bad idea. I have a switch that disconnects the battery from the system so I can plug in the USB.

For the next version of the driver board I would think a 3.3V regulator would be useful so the driver board can just power the Launchpad by its self.

I got a few made last fall and am using them (successfully) in a couple of little projects. I’m curious about your statement “feeds into the voltage regulators on the Launchpad”…. could you elaborate on how you have that connected? I am using an external 3.3V regulator right now because I thought I had to.

Also, I don’t see where I can purchase one of these, do you know if you wil sometime in the future?
