good book for c indepth we can read

HMC5883L STM32驱动代码，采用I2C总线进行通信的。(HMC5883L STM32 driver code, using the I2C bus communication.)

说明：  该工程是基于LPC1857单片机开发的数控程序，包含了SDRAM、EMMC驱动代码，还在单片机上移植了UCOSIII系统，并在此基础上移植了FATFS文件系统、LWIP1.4.1网络协议栈。该工程是实际项目中的源码，稳定性绝对有保障，供大家参考。(The project is based on LPC1857 microcontroller development of CNC program, including SDRAM and EMMC driver code, and also transplanted UCOSIII system on MCU. On this basis, FATFS file system and LWIP1.4.1 network protocol stack were transplanted. The project is the source of the actual project, the stability is absolutely guaranteed for everyone's reference.)
