Description: 多数文档并不完善,经参考：
1. 世界变换 World Transformation. 局部坐标 宇宙坐标. Local Space World Space.
局部坐标空间化： x --→ xW=x0
变换矩阵书写习惯：
物体的世界矩阵W为4 4矩阵, 前3行为三个标架的齐次坐标,末行为中心点的齐次坐标.
物体=标架=矩阵
移动物体标架即左×其矩阵： e为局部标架, e0为宇宙标架, 则 e=We0. 一般情况e0为单位阵,故e=W.
设x0为宇宙坐标, x为局部坐标. 则 xe=x0e0, xWe0= x0e0, x0=xW, W=e. 转换到世界坐标即右×矩阵.
设空间点x0相对于物体 e1, e2的坐标分别为x1,x2, 则 x1e1=x0e0=x2e2, 故 x2= x1e1∙ e2-1, 即从一个局部坐标变换到另一个局部坐标,先右×自己的矩阵,再右×对方的矩阵之逆矩阵.

Description: stm8s M24C64 iic eeprom 源码-This firmware provides a basic example of how to use the I2C firmware library and
an associate I2C EEPROM driver to communicate with an I2C EEPROM device (here the
example is interfacing with M24C64 EEPROM)
I2C peripheral is configured in Master transmitter during write operation and in
Master receiver during read operation I2C EEPROM.
The speed is set to 200kHz and can be configured by modifying the related define
in stm8s_ _i2c_ee.h file.
For M24C64 devices all the memory is accessible through the two-bytes
addressing mode and need to define block addresses. In this case, only the physical
address has to be defined (according to the address pins (E0,E1 and E2) connection).
This address is defined in stm8s_ _i2c_ee.h (default is 0xA0: E0, E1 and E2
tied to ground).
The EEPROM addresses where the program start the write and the read operations
is defined in the main.c file.
First, the content of Tx1_Buffer is written to the EEPROM_WriteAddress1 and the
