最近学习28069m和8305套件，对其中的电流电压偏置值的设置不是很明白，看到设置的值都是不同的，
#define I_A_offset (1.20)
#define I_B_offset (1.20)
#define I_C_offset (1.20)
//! \brief ADC voltage offsets for A, B, and C phases
//! \brief One-time hardware dependent, though the calibration can be done at run-time as well
//! \brief After initial board calibration these values should be updated for your specific hardware so they are available after compile in the binary to be loaded to the controller
#define V_A_offset (0.50)
#define V_B_offset (0.50)
#define V_C_offset (0.50)
这里的1.2和0.5是如何确定的？
同样试着打开别的套件的user.h程序，有的是三个值不同，有的甚至是负值，因此很是疑惑。
