  • Basic Stamps and VFDs

    Is it complicated to hook-up a VFD to a BASIC stamp?

    The reason I want to do this is because I want to have a clock in my car (my only clock is my radio.. and thats going out the window).

    So basically the Stamp would keep time and the vfd would display it... Simple.. right?

    Thanks

    The hardware isn't *too* complicated. You will need to program the stamp to do what you want, of course. If you get the serial basic stamp, you could write a program to allow the VFD to connect to your PC via the serial port, which would be an added bonus.

    Basically the software would have to poll one of the serial port's signal lines and when it detected that the PC was off, it would then go into "clock mode" and show the date and time, etc. You could take some of the C code used to control character LCDs and port it to pbasic to run on the stamp. Most of the code is just outputting the appropriate 1's and 0's to different pins on the VFD.

    You could even get fancy and connect temperature sensors to the stamp and have it show the inside and outside temperatures along with the clock

    I'm not sure what stamp model you would need, but be sure it has enough data lines to drive the VFD, and that it has an onboard serial port and RTC (Real-time-clock) for keeping the time. If you want to connect external sensors later on, make sure it also has some A/D channels on it.

      J,

      It's like you read my mind! The temperature (int/ext) is exactly one of the thinkgs I want to do!

      The only difference is that I will have a TFT screen in my car, this VFD will be a dedicated clock... Since the only clock in my car was on my car radio.

      Thanks!!

        Why can't you just have the computer display the time?

          I could, but I figured I wanted a dedicated clock.. Not only for when the pc is on,
          but when it's off too.

          So in short... I'm doing it just for the hell of it

            I have a 92 Honda Accord and I'm real tempted to rip out the VFD clock (7 segment display!) and put in a nice 20x4 VFD module. It looks as though there might be just enough room to fit the new VFD in place and have it look like it was supposed to go there.

            More research is needed...
