Introducing swddude I love the ARM Cortex-M series of microcontrollers. The sheer computational power they pack into a teensy, low-power package is almost embarrassing. But, many Cortex-M parts are small — 4x4 millimeters small — and don’t have the
Implementation of Serial Wire JTAG flash programming in ARM Cortex M3 Processors The goal of the project was to use the Serial Wire JTAG protocol implemented in the ARM cortex processors for programming the flash memory of it. JTAG was actually imple
JTAG was the traditional mechanism for debug connections for ARM7/9 parts, but with the Cortex-M family, ARM introduced the Serial Wire Debug (SWD) Interface. SWD is designed to reduce the pin count required for debug from the 5 used by JTAG (includi
此书有点深,记录点自己能够看懂的. 1.内存管理一章:讲到变量的类型.生存周期.内存分配. auto static register 局部变量,全局变量 malloc free 内存碎片,消除内存池的一个常见的策略是可以使用分配池 2.共享内存一章:讲到如何编写可重入函数,很多库函数都是设计为可重入函数的,函数体内不能有全局变量和静态变量,有的参数可以通过指针(或二级指针)实现. const类型限定符,使用方法有以下几种: const int p; const int p; int const
1 arm处理器的发展历史 arm1 arm2 arm3 arm6 arm7 arm9 arm11 arm cortex 2 arm处理器现状 arm cortex A a即application,即应用处理器,主要用在智能手机.平板电脑和服务器上. arm cortex M m即mcu,即单片机上的处理器,它的特点就是成本低,功耗低. arm cortex R r即real time,用于实时性要求高的领域,比如汽车.
