获取单片机唯一id（stm32获取单片机唯一id）

stm32唯一id：

不同型号的stm32单片机，id不在同一地址上！具体地址可以通过用户手册中的Device electronic signature>Unique device ID register来获取。

1. stm32f072：

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

2. stm32f103：

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

3. stm32f407：

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