还有就是在rtthread studio中，使用at32库的时候，有些驱动的使用用法注释没有更改，导致理解出错
例如：
board.h中的注释
/*-------------------------- SPI CONFIG BEGIN --------------------------*/
/** if you want to use spi bus you can use the following instructions.
*
* STEP 1, open spi driver framework support in the RT-Thread Settings file
*
* STEP 2, define macro related to the spi bus
* such as #define BSP_USING_SPI1
*
* STEP 3, copy your spi init function from stm32xxxx_hal_msp.c generated by stm32cubemx to the end of board.c file
* such as void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)
*
* STEP 4, modify your stm32xxxx_hal_config.h file to support spi peripherals. define macro related to the peripherals
* such as #define HAL_SPI_MODULE_ENABLED
*/
/*#define BSP_USING_SPI1*/
/*#define BSP_USING_SPI2*/
/*#define BSP_USING_SPI3*/
