在选择LD启动文件时,需要确保其与目标硬件的兼容性,以确保程序能够正确启动和运行。 MD(Medium Density)启动文件 MD启动文件适用于STM32的中密度系列,如STM32F1和STM32F3系列。这些微控制器具有更高的性能和更多的内存,因此MD启动文件相对于LD启动文件更为复杂。MD启动文件不仅关注基本的硬件初始化和系统时钟设置,还...
STM32有4种Flash module organization,分别是:low-density devices(32KB,1KB/page)、medium-density devices(128KB,1KB/page)、high-density devices(512KB,2KB/page)、connectivity line devices(256KB,2KB/page)、XL-density(devices(1M,2KB/page)。从上面分析可知,STM32F103RBT6的Flash是128KB,可见是medium-den...
CCM data RAM:Code区域是用I-Code和D-Code访问,作用是为了加快数据处理速度。 system memory :STM32在出厂时,已经固化了一段程序在System memory(medium-density devices的地址为:0x1FFF_F000,大小为2KB)存储器中。这段程序就是一个固定好的,并且没法修改的Boot Loader Options Bytes :可以按照用户的需要进行配置...
根据字面意思, hd(High Density )是大容量, md(Medium Density ) 是中容量 ld (Low Density ) 是小容量 可是启动不止三个,大中小之外还有后面跟vl后缀的 并且还有后缀cl 和 xl 的文件。 解释一下 CL:connective line 指的是互联型产品f105xx和stm32f107xx 系列 Xl :extreme line 超高密度型 产品 这种应该...
medium-density performance line family includes devices in six different package types: from 36 pins to 100 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family. These ...
Flash信息区(Information block),该区域又可以分为Option Bytes和System Memory区域;System Memory:STM32在出厂时,已经固化了一段程序在System memory(medium-density devices的地址为:0x1FFF_F000,大小为2KB)存储器中。这段程序就是一个固定好的,并且没法修改的Boot Loader(见编程手册PM0042这种描述)。Option Bytes...
SystemCoreClock is set to 72 MHz for Low-density, Medium-density, High-density and Connectivity line devices and to 24 MHz for Low-Density Value line and Medium-Density Value line devices The objective is to generate 7 PWM signal at 17.57 KHz: ...
System Memory:STM32在出厂时,已经固化了一段程序在System memory(medium-density devices的地址为:0x1FFF_F000,大小为2KB)存储器中。这段程序就是一个固定好的,并且没法修改的Boot Loader(见编程手册PM0042这种描述)。 Option Bytes:可以按照用户的需要进行配置(如配置看门狗为硬件实现还是软件实现);该区域除了互联...
The STM32F103xx medium-density performance line family includes devices in six different package types: from 36 pins to 100 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this...
The STM32F103xx medium-density performance line family incorporates the high-performance ARM®Cortex®-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and ...
