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…

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…

依据前文伏击战场景手稿, 用Tile Studio "草草"制作出该场景的地图: 生成的C源码: #ifndef _open_war_1Gfx_c #define _open_war_1Gfx_c #ifndef _GFX_BITMAP_DATA #define _GFX_BITMAP_DATA /* structure with bitmap data */ typedef struct GFX_BITMAP_DATA { char * BitmapIdentifier; int B…

ARM7 ARM9 ARM Cortex M3 M4 区别 arm7 arm9 可以类比386和奔腾, 不同代,arm9相比arm7指令集和性能都有所增强,arm7和arm9都有带mmu和无mmu的版本,不过大多的arm7都不带,而大多的arm9的都带.所以一般是arm7跑实时操作系统像ucos做简单的控制应用,而arm9跑linux,cortex是更新一代,分高端的A系列和和低端的M系列,来接arm9和arm7的班 一般情况下ARM7 Cortex-M3 Cortex-M4可以认为是一类,M3…
