5. About code transplantation
· When transplanting STM32 code to Liangshanpai, pay attention to the main frequency of both, especially when transplanting STM32F1 series MCU.
· It is recommended to transplant the adaptation code of STM32F4 series MCU to Liangshanpai, because the main frequency difference between the two is not big, and they can be transplanted directly, and only the library files and library functions in the code need to be changed.
