摘　　要：单片机的在应用编程(In-Application Programming,IAP)功能指的是在应用中编程,即允许单片机在运行自己的应用程序时自我更新,通过特定的机制对程序存储器进行更新或修改,其目的就是为了在产品使用后可以方便地通过预留的通信接口远程对产品中的固件进行升级更新。在工程应用中,经常会出现产品被安装在某个特定的机械结构中的情况,更新程序时,拆机很不方便,使用IAP技术能很好地降低工作量。产品MCU选择STM32F405RG,该系列芯片面向需要在小至4 mm×4.2 mm的封装内实现高集成度、高性能、嵌入式存储器和外设的医疗、工业与消费类应用。STM32F405/415提供了工作频率为168 MHz的Cortex^(TM)-M4内核(具有浮点单元)的性能。The In-Application Programming(IAP)function of the one-chip computer refers to programming In the Application,that is,allowing the one-chip computer to self-update when running its own application,and to update or modify the program memory through a specific mechanism.Its purpose is to facilitate remote firmware upgrade and update of the product through the reserved communication interface after use.In engineering applications,it′s common for products to be installed in a specific mechanical structure,making it inconvenient to disassemble the machine when updating the program.The use of IAP technology can effectively reduce workload.The product MCU selected the STM32F405RG,which is aimed at medical,industrial and consumer applications that require high-integration,high-performance,embedded memory and peripherals in packages as small as 4 mm×4.2 mm.STM32F405/415 provides the performance of Cortex^(TM)-M4 kernel(with floating-point units)with a working frequency of 168 MHz.
