 The Digilent Digital Discovery™ is a combined logic analyzer and pattern generator instrument that was created to be the ultimate embedded development companion. The Digital Discovery was designed to optimize channels, speed, and portability. The small form factor facilitates easy storage and provides a whole suite of advanced features to allow you to debug, visualize, and stimulate digital signals for most embedded projects. The digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires; alternatively, the Digital Discovery High Speed Adapter and impedance-matched probes can be used to connect and utilize the inputs and outputs for more advanced projects. The Digital Discovery is driven by the free [[/reference/software/waveforms/waveforms-3/start|WaveForms]] (3.5.4 or later) software and can be configured to be any of the instruments below:  The Digilent Digital Discovery™ is a combined logic analyzer and pattern generator instrument that was created to be the ultimate embedded development companion.
