Help me develop a graphical interface to display values on a TV set

graphical interface

Hi
Later in the year we are going to develop a graphical interface for industrial instrumentation: thermocouples,rtds, pressure, engine speed, CAN bus data etc.

Basically i would like to graphically display these analog and digital values on a television (SCART or composite)

Ideally i would like to achieve graphics similar to these: https://www.dundas.com/Gallery/Gauge/NET/index.aspx?ImgGroup=Other
Volume: 1-999

All i really need is lots of gauges and bar graphs and possibly some xy plots like a oscilloscope i.e. number of analog values trending over time.

Im assuming NTSC/PAL are still the standard? (is there a new digital equivalent i need to target)

Im also assuming all i really need is some form of NTSC/PAL encoder IC like the AD723 from analog devices.

Or do i really need a graphics procssor like the DaVinci from TI? (already using TI processors)

Im NOT looking for circuitry etc just a point in the right direction.

Many Thanks for your help
Best Regards
Quinn

Re: graphical interface

Some guys I work with used a Spartan 3 starter board to display stuff on a monitor. I'm not sure exactly what they did, or what sort of graphic capability it has, but it may be worth a look.

Thanks for the tip, Ill have a look on the Xilinx website and see whats available on the dev boards.

Any more suggestions guys?

Re: graphical interface

FPGA is probably best way. You can generate arbitrary video signal and make some hardware acceration for graphics.

Here is link to VGA controller, character generator and bouncing ball implemented in XILINX FPGA:

and here Pong game example:

Just for inspiration.
