stm32 UID全球唯一標識碼總結

stm32f103系列單片機都有UID，96位，放在3個32位寄存器里面，base address：是?0x1ffff7e8，偏移地址分別是：0,4,8;

//下面這3個是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?里面Device electronic signature找到了?！

基地址：?-0x1ffff7ac

?stm32?f030單片機發現STM32F030x4/6/8/C and STM32F070x6/B的reference manual里面Device electronic signature沒有找到Unique device ID register!!!怎么辦？想用stm32f030的UID做模塊識別！直接硬件測試，用3個f030單片機測試STM32F0x1/STM32F0x2/的UID，發現只有基地址有個24位或者20位的不同的值，4和8都是一樣的！所以可以斷定：0x1ffff7ac存放的32位數據就是stm32f030UID！

引用別人的***************

最新的STM32F0 Reference manual有 Device electronic signature章節：Base address: 0x1FFF F7AC?

STM32F0 uid Base address: 0x1FFF F7AC

偏移地址,00 04 08

stm32f030是有ID號的，是個32位的ID號, 具體見芯片手冊.?
