* Systems using the Linux I2C driver stack can declare tables of board info * while they initialize. This should be done in board-specific init code * near arch_initcall() time, or equivalent, before any I2C adapter driver is * registered. For example, mainboard init code could define sev...

In some situations, it can be helpful to set up two (or more!) Arduino and Genuino boards toshare information with each other(彼此共享信息).In this example, two boards are programmed to communicate with one another in aMaster Reader/Slave Sender configuration(配置)via theI2C synchronous seri...

Generate and specify a unique trace GUID in I2ctrace.h. Refactor the driver name, functions, comments, etc., to better describe your implementation. Code tour Implementing the SPB DDI The following are relevant functions in the SkeletonI2C driver for implementing the SPB DDI. ...
