    Smile Top link: µScope using 16f675

    This is real good. This guy has used a PIC 16f675 to make a fully self-contained CRO. For about $5 you can build this thing that simply just plugs into any spare composite video in on your TV. Bandwidth is only a few KHz, but for $5 could you really complain?

    Even more notable is that he has also reinvented the game Pong using nothing more than a 16f675!
    (*Very scary)

    maybe i have some eyes problem... but it use a 12F675 which make it, by far, more impressive...

    Amazing what we can do with ONLY 1K of code and a 8 pin PIC...

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Right you are. It's uses a 12f675. I think I must be the one with an eye problem. All round very impressive indeed.

    Default displaying algorithm

    Hi can anybody tell me the displaying algorithm of a digital storage oscilloscope?
    I am trying to build a oscilloscope using a FPGA. Okay I have stored the samples from ADC output to FPGA SDRAM. Now what techniques or algorithms can I use to display the samples stored in a VGA monitor.
    Are there any special techinque which can be used to manipulate the stored sampled data and finally display in VGA monitor...
    Please anybody help me

    One of the recent magazines had a 2-part series on this. Don't remember which one off hand, but it was either EPE, Circuit Cellar, or Nuts & Volts.
