A ble and BT differencesIn fact, I know many programmers do not like to read in addition to the code of the document, because sometimes these too lengthy documents for programming and no more benefits, with the Protocol, interface, demo almost a lot of people can write very good quality code. But in fact, deeper into the programming is less reading, reading documents can solve many of the difficulties encountered in programming, such as large data tra

This article begins by analyzing the kernel's I2C subsystem. Description: 1. The kernel version of the analysis is 2.6.37.1 2. Development Board for TQ2440, onboard ARM9 (s3c2440) 3.I2C equipment for AT24C02 4. The sequence of analysis is the registration order of the Kernel I2C subsystem (that is, the order in which this series of articles is published). It is
