Digilent Digital Discovery™ with High-Speed Adapter

Digilent Digital Discovery™ is a combined logic analyzer and pattern generator that was designed to be the ultimate embedded development companion. The Digital Discovery features a small form factor, facilitating portability and easy storage. Digital Discovery provides a suite of advanced features to allow the user to debug, visualize, and simulate digital signals for most embedded projects. The Included Digital Discovery High-Speed Adapter and impedance-matched probes can also be used to connect and utilize the inputs and outputs for more advanced projects.

The High-Speed Adapter connects to a 32-pin connector on the Digital Discovery and offers an alternative to the default 2x16 flywire assembly. It provides access for up to 24 High-Speed Logic Probes and allows increased sample rates for up 800MS/s on the Digital Discovery. The High-Speed Adapter is not keyed, and both orientations can be used as the twisted wires are not color-coded.

The Digital Discovery is driven by the free WaveForms (3.5.4 or later) software and can be configured to be any of the below instruments:

  • 32-channel digital logic analyzer (1.2V to 3.3V CMOS, 8 channels at 800MS/s*, 16 channels at 400MS/s*, and 32 channels at 200MS/s)
  • Digital Bus Analyzers (SPI, I2C, UART, CAN, Parallel)
  • 16-channel pattern generator (1.2V to 3.3V CMOS, 100MS/s)
  • 16-channel virtual digital I/O including buttons, switches, and LEDs
  • A programmable power supply of 1.2V to 3.3V/100mA

*Note: to obtain speeds of 200MS/s and higher, the High-Speed Adapter must be used. 

The Digital Discovery was designed for anyone embarking on embedded development. Its features and specifications were deliberately chosen to maintain a small and portable form factor, withstand use in a variety of environments, and keep costs down while balancing the requirements of operating on USB Power.

WaveForms™

WaveForms provides a suite of graphical instrument panels that give full access to the Digilent Analog Design hardware, such as the Digital Discovery, Analog Discovery, Analog Discovery 2,  and Electronics Explorer. Custom applications can also be written for these devices, using the WaveForms SDK (Software Development Kit), which provides the header/library files and documentation to access the API for the DWF Library.
