Monitoring Sniffer Tibbo IO Ninja I2C/SPI Tap
Ethernet Tap is an affordable sniffer for monitoring Ethernet traffic flowing through a single Ethernet connection. The Tap passes the Ethernet traffic through with a delay equal to about 5.2uS.
The I2C/SPI Tap for IO Ninja is an affordable sniffer for monitoring
SPI communications. Our sniffer allows you to tap into the lines of
SPI links and immediately view the captured data bytes in IO Ninja software — in real time and using our innovative dual-hex view tailor-suited for the inherently full-duplex
All inputs of the I2C/SPI Tap are available on a convenient quick-release terminal block. The board also features LEDs for the
SPI line status indication (
SS), which helps with quick troubleshooting of wiring issues.
This sniffer device must be used with the I2C/SPI Tap plugin.
SPI firmware (FPGA configurations) for this Tap include test generators producing sustained test traffic at 400KHz and 24MHz respectively.

To receive the test traffic, connect two or four wires as shown on the diagram below:
- USB-powered, no additional external power necessary;
- Supplied with a
- Based on Inter MAX10 FPGA;
- Incorporates an
SPItest sequence generator for self-testing the Tap;
- Has 16 buffered IO lines
D15connected to a quick-release terminal block;
- All buffers act as level shifters allowing the Tap to work with logical signals as high as 5V and as low as 1.8V;
- Eight LEDs onboard:
- Two general-purpose green LEDs
M1for mode and status indication;
- Four yellow LEDs for indicating the state of IO lines
D3(sufficient for I2C and SPI);
- Product functionality may be expanded in the future:
- Onboard FPGA is reconfigurable via the USB interface;
- Sixteen IO lines provide ample room to grow;
- It is envisioned that the product's abilities may be expanded to handle such protocols as...
- Single-wire bus;
- ...and more!

This number depends on the host PC's performance and its workload. Captured data may be lost if PC's USB channel is unable to receive it in a timely manner. Our tests have shown that an average i7-based desktop PC that is not performing other time-critical tasks easily captures sustained SPI traffic with clock speeds up to 24MHz.
