Two days ago, Raj from embedded-lab informed me about his latest article that he uploaded in his website. He wrote the theory regarding the I2C (spelled Ai squared C) protocol. If you have work with microcontroller, then you probably have mess with this addressable bi-directional communication protocol. Unfortunately, there are people who -even though they use devices that communicate with I2C- they know jack about this marvelous rock-solid flexible protocol... You know for whom I'm talking about, don't you? I strongly suggest you read how I2C works, for there are many new things that you can learn from it.
Unfortunately, i had no time yesterday to upload new blog entries, but better late than never. Follow this link to go to Rajs' page. Thanks a lot [Raj]
