stm32 UID全球仅有标识码总结

UID：unique id差异于单片机的Deveice ID（区别是stm32f103仍是stm32f030的单片机）

stm32f103系列单片机都有UID，96位，放在3个32位寄存器里边，base address：是​0x1ffff7e8，偏移地址分别是：0,4,8;

//下面这3个是stm32f103的uid

printf(” 0x1ffff7e8 id:0x%X”,(*(volatile uint32_t *)0x1ffff7e8));

printf(” 0x1ffff7ec id:0x%X”,(*(volatile uint32_t *)0x1ffff7ec));

printf(” 0x1ffff7f0 id:0x%X”,(*(volatile uint32_t *)0x1ffff7f0));

STM32F0x1/STM32F0x2/STM32F0x8​里边Device electronic signature找到了​！

基地址：​-0x1ffff7ac

​stm32​f030单片机发现STM32F030x4/6/8/C and STM32F070x6/B的reference manual里边Device electronic signature没有找到Unique device ID register!!!怎么办？想用stm32f030的UID做模块辨认！直接硬件测验，用3个f030单片机测验STM32F0x1/STM32F0x2/的UID，发现只要基地址有个24位或许20位的不同的值，4和8都是相同的！所以能够判定：0x1ffff7ac寄存的32位数据便是stm32f030UID！

引证他人的***************

最新的STM32F0 Reference manual有 Device electronic signature章节：Base address: 0x1FFF F7AC​

STM32F0 uid Base address: 0x1FFF F7AC

偏移地址,00 04 08

stm32f030是有ID号的，是个32位的ID号, 详细见芯片手册.​
