The I2C/SPI Tap is an affordable sniffer for monitoring I2C and SPI communications. The sniffer taps into I2C and SPI lines and sends the recorded data to IO Ninja software in real time.
The Tap reliably captures I2C traffic at clock speeds of up to 700KHz and SPI traffic at speeds of up to 24MHz. The product features a convenient quick-release terminal block and multiple status LEDs.
The Tap is based on the MAX10 FPGA. The configuration (firmware) of this flash-based FPGA is uploadable from IO Ninja via the device's USB port. New configurations supporting additional synchronous protocols, such as Quad-SPI, are planned to be released in the future.
The I2C/SPI Tap must be used with the I2C/SPI plugin of IO Ninja software.
