Debug your embedded systems from the home office

Use USB Logic Analyzer and Pattern Generator to debug, visualize, and simulate signals in digital systems

The quarantines are forcing an increasing number of engineers and tech employees to work from home (WFH). With Digilent Digital Discovery, engineers can debug digital systems from home to continue the hardware and software development.

Digilent Digital Discovery is a USB Logic Analyzer, Protocol Analyzer and Pattern Generator. 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 project.

Digital Discovery is now available from Farnell / Newark / element14

Driven by the free WaveForms software application, Digital Discovery can be configured to be the following instruments:

  • 24-channel digital logic analyzer (1.2…3.3V CMOS, up to 800MS/s (with the High Speed Adapter))
  • 16-channel pattern generator (1.2…3.3V CMOS, 100MS/s)
  • 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications
  • Digital Bus Analyzers (SPI, I²C, UART, I2S, CAN, Parallel)
  • A programmable power supply of 1.2…3.3V/100mA. The same voltage supplies the Logic Analyzer input buffers and the Pattern Generator input/output buffers, for keeping the logic level compatibility with the circuit under test.

WaveForms Application Software

WaveForms features a computer and laptop friendly user interface that has the feel of traditional benchtop equipment. The software is compatible to Windows, Linux, MAC, and Raspberry Pi 4. The WaveForms Software Development Kit (SDK) provides libraries and examples in Python, C++, and more so that advanced users can build custom applications or automated test.

Debug your embedded design. Look at the Xilinx Zynq boot sequence

In the process of developing a new Xilinx Zynq SoC platform, it’s important to know the specifications of the hardware on the board and see the timing of signals. Unfortunately, the speed of the QSPI transactions in the boot sequence isn’t always an evident specification. This application note uses the Digital Discovery to visualize the boot sequence to determine timing.
