stm32惟一id：

不一样型号的stm32单片机，id不在同一地址上！具体地址能够经过用户手册中的Device electronic signature>Unique device ID register来获取。

stm32f072：

uint32_t id[3]; id[0] = *(__IO uint32_t *)(0x1FFFF7AC); id[1] = *(__IO uint32_t *)(0x1FFFF7B0); id[2] = *(__IO uint32_t *)(0x1FFFF7B4);

stm32f103：

uint32_t id[3]; id[0] = *(__IO uint32_t *)(0x1FFFF7E8); id[1] = *(__IO uint32_t *)(0x1FFFF7EC); id[2] = *(__IO uint32_t *)(0x1FFFF7F0);

stm32f407：

uint32_t id[3]; id[0] = *(__IO uint32_t *)(0x1FFF7A10); id[1] = *(__IO uint32_t *)(0x1FFF7A14); id[2] = *(__IO uint32_t *)(0x1FFF7A18);
