Video DVM - Video-DVM is a very cheap DVM that shows how an output as complex as a
videocomposite signal can be generated entirely in software: two I/O pins and three
resistors are all the hardware required. Connected to any TV set it displays voltages,
included max and min peaks, using both giant digits and an analog bar-display . A
serial data output for computer data logging is provided, too...(added 05/06) |
