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
各常见芯片信息如下：
