RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1,ENABLE);RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1,DISABLE);

这段代码是用来控制STM32的SPI1外设的复位功能的。根据引用\[1\]，函数RCC_APB2PeriphResetCmd()用于强制或释放APB2总线上的外设复位。第一个参数RCC_APB2Periph_SPI1指定了要复位的外设，而第二个参数ENABLE表示要强制复位该外设。根据引用\[2\]，如果NewState参数不等于DISABLE，那么就会将RCC_APB2Periph参数的对应位设置为1，即使能该外设。如果NewState参数等于DISABLE，那么就会将RCC_APB2Periph参数的对应位设置为0，即禁用该外设。所以，RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1,ENABLE)会强制复位SPI1外设，而RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1,DISABLE)会释放SPI1外设的复位。
