Everything the hobbyist, maker or professional engineer needs to know about the I2C bus! https://nostarch.com/book-i²c No Starch Press https://nostarch.com

Because technology changes so fast, it would be impossible to keep The Book of I2C up-to-date when new I2C devices become available or when some new single-board computer (SBC) supporting I2C appears. To help rectify this problem, this site contains several on-line chapters that cover new products (that became available after the book was written) as well as reduce the size (and cost) of The Book of I2C. Click on the links below to view (or download) these on-line chapters. Note: from a publication point of view, these chapters are all rough drafts. This means that they have not gone through the usual editorial and technical review that No Starch Press normally performs on published material. Please post any issues or suggestions you find to the I2C forum at https://randallhyde.com/Forum/
