I2C Data Bus Reader Everything on the PC screen, via USB

摘要

The Inter-Integrated Circuit bus - or I2C bus - is frequently used for communication between integrated circuits. It is often useful to know what data is being sent about this bus. The circuit described here reads the I2C data and sends it via the USB to a PC that then hexadecimal form on the screen displays. Optionally, the data can be filtered to select data with specific addresses.
