摘要
针对RT-Thread操作系统下I^2C总线驱动展开研究,对驱动结构进行介绍与分析。以STM32F407VG上的软件I2C驱动移植为例介绍了驱动移植步骤,并通过STM32F407VG读写24LC02B的实例,详细介绍I^2C编程步骤及技术细节。最后通过实验验证I^2C驱动移植及编程的有效性。实验结果表明,RT-Thread操作系统下的I^2C总线驱动结构简洁,且易于移植及进行程序设计。
Aiming at the 12 C bus driver of RT-Thread operating system, the structure of 12 C bus driver is presented and analyzed. The 12 C driver migration process is introduced with the example of the I2C drive migration for STM32F407VG, and by the read/write 24LC02B through STM32F407VG, the PC programming steps and technical details are introduced. Finally, an experiment is taken to verify the ef- fectiveness of the migration and programming of I2C driver. The experiment results show that the I2C bus driver structure of RT Thread is simple and easy for migration.
