STM32 header file and source file

For STM32F4xx_StdPeriph_Driver, an important source file: stm32f4xx_ppp.h: peripheral header files. ppp where only one code, in fact, specific names peripherals, such as ADC, DMA and the like. Graft in actual use depending upon the desired peripheral selectivity. stm32f4xx_ppp.c: Peripherals source file. ppp where only one code, in fact, specific names peripherals, such as ADC, DMA and the like. Graft in actual use depending upon the desired peripheral selectivity. stm32f4xx_conf.h: Peripheral driver configuration file. Peripherals header by modifying the files contained in the user to enable or disable peripheral drivers. Further, in this folder open macro definitions USE_FULL_ASSERT, fault detection criteria by preprocessing peripheral runtime library enable or disable. stm32f4xx_it.h: headers. Including all interrupt handler prototype. In the Project \ STM32F4xx_StdPeriph_Templates in. stm32f4xx_it.c: template interrupt source, interrupt name of the function you want to interrupt the startup file name to the same scale. In addition, stm32f4 standard peripheral firmware libraries, as well as in the corresponding folder CMSIS DSP library: DSP_Lib and Lib. DSP_Lib mainly for DSP library and source code examples; Lib is compiled, and the lib files for different kernels STM32 series MCU used. The following is the important source file folder CMSIS firmware library Transplantation: core_cm4.h: custom kernel function, such as the structure and related registers NVIC Systick configuration. core_cmFunc.h: kernel core function interface header file. core_cmInstr.h: a core comprising a number of core specific instructions. core_cmSimd.h: includes processing associated with the compiler. stm32f4xx.h: it contains definitions stm32f4 register structure (similar to c51 of reg52.h). system_stm32f4xx.h: system_stm32f4xx.c header files. system_stm32f4xx.c: stm32f4 system clock configuration. startup_stm32f40_41xxx.s: startup file: setting the initial value of the SP; set the initial value of the PC; set the address of an interrupt vector table; configure the clock; set the stack; calls main. The first call system_stm32f4xx.c startup file inside systeminit () () before calling main. Integration article from: csdn Edit: ymf, Read more
