Hardware Serial Monitor
This Hardware Serial Monitor plugin lets you monitor UART
, SPI
and I2C
serial communications at the level of electrical signals.
Our hardware sniffer is a USB 3.0 device powered by Cypress EZ-USB FX3 chip. It detects signal edges on up to 16 lines and reports those — together with high-precision timestamps — to IO Ninja. The Hardware Serial Monitor plugin of IO Ninja, in turn, decodes those timestamped signal edges according to the pre-selected serial interface (UART, SPI, I²C) and interface-specific settings (UART baud rate, SPI mode, endianness, etc) to produce human-readable representation of the actual data flow.
