因为需要自动适配芯片进行系统配置，所以我们有必要通过读取一些系统寄存器来获取必要信息。
我们的代码需要兼容STM32F1/GD32F1/STM32F0/STM32F4
代码如下：
#ifdef STM32F0XX
void* p = (void*)0x1FFFF7AC;
#else
void* p = (void*)0x1FFFF7E8;
#endif
memcpy(ID, p, ArrayLength(ID));
CPUID = SCB->CPUID;
uint MCUID = DBGMCU->IDCODE; // MCU编码。低字设备版本，高字子版本
RevID = MCUID >> 16;
DevID = MCUID & 0x0FFF;
_Index = 0;
#ifdef STM32F0XX
FlashSize = *(__IO ushort *)(0x1FFFF7CC); // 容量
#else
FlashSize = *(__IO ushort *)(0x1FFFF7E0); // 容量
#endif

未解决问题：
1，有人说F0的ID只有32位，这个没有找到确切资料
2，GD芯片F130/F150没有读取得到DevID和RevID，而同为F0固件库的F030可以
3，STM32F103和GD32F103还有GD32F130/F150都可以通过0x1FFFF7E0读取得到内置闪存大小，而STM3F030不行，是不是因为这个是M3地址，而M0地址不同？如果130/150使用F0库缺使用M3地址，使用起来就麻烦了。
4，GD32F130/GD32F150上中断向量表映射到RAM的0x20000000失败，调用SYSCFG_MemoryRemapConfig配置SYSCFG->CFGR1为SYSCFG_MemoryRemap_SRAM后再读取发现没有生效，系统仍然使用Flash上的中断向量表。
