JTAGulator is an open source hardware tool that assists in identifying On-chip debug (OCD) connections from test points, vias, or component pads on a target device.
Key Features:
- 24 I/O channels with input protection circuitry
- Adjustable target voltage: 1.2 V to 3.3 V
- Supported target interfaces (as of firmware v1.1): JTAG/IEEE 1149.1, UART/asynchronous serial
- USB interface for direct connection to host computer (PC, Macintosh, or *nix)
Application Ideas:
- Discover on-chip debug interfaces
- Simple logic analyzer
- Propeller development board
Includes: JTAGulator device, one set of data probes
