Overview

The Digilent Digital Discovery is a portable USB logic analyzer and digital pattern generator designed to optimize the debug and test of embedded systems. It features 24 high-speed digital I/O pins capable of 100 MHz bandwidth and supports logic levels from 1.2V to 3.3V. The device integrates various instrumentation functions including a protocol analyzer and virtual I/O into a single PC-connected suite.

Why Choose This Part

It offers 256 MB of hardware buffer memory for deep data captures and provides 5V-tolerant inputs for interfacing with various logic families. The adjustable logic levels (1.2V to 3.3V) make it highly versatile for modern low-power microcontrollers and legacy hardware alike.

Applications

Protocol Analysis
Decoding and debugging of SPI, I2C, UART, CAN, and I2S communications in real-time.
Embedded System Debugging
Using 24 digital channels to monitor multi-node system behavior and timing relationships.
Digital Signal Generation
Generating custom digital patterns and clock signals to stimulate a DUT (Device Under Test).
Automated Testing
Utilizing cross-triggering and data export features for long-term validation and automated scripts.

Getting Started

Connect the device to a PC via USB and install the WaveForms software, which provides the GUI for all instrumentation functions. Use the included fly-wire cables to connect the 24 GPIO pins to your breadboard or target header for immediate signal acquisition.
