USB to I2C and SPI Terminal and Analyser

This device presents itself as a COM port and allows you to control I2C or SPI devices directly from a terminal or terminal emulator running on the PC. It comes with a complete foundation tutorial and user guide and works with 3.3V & 5V logic. This is excellent for learning about I2C or SPI. Works with EEPROMS, humidity, temperature, gas sensors, displays. The I2C will also discover addresses and so will enable you work with unknown systems.

Uses

  • Reading / writing EEPROMS **
  • Learning about I2C or SPI
  • Controlling I2C and SPI devices from a PC
  • Reverse engineering of I2C busses
  • Analysing an I2C bus for signals such as stop, address start etc.
  • Working with an I2C or SPI device before being implemented into a system
