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 up-grade 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™-M4 kernel(with floating-point units)with a working fre-quency of 168 MHz.
