Hello,
I have found this little oscilloscope project (URL) that uses a single A/D converter connected directly to the LPT port. It uses one pin of the port as an EXT trigger, which is desirable in my application. The author notified me that it can display signals up to 30-40KHz or so.
1. I wonder, what is the thing that limits the display of signals to 30MHz? Is it this A/D converter or the LPT or both?
2. Is there any way I can convert this to display signals to 30MHz? Any ideas are welcome.
