单片机编程  at91rm9200启动过程教程

at91rm9200启动过程教程系统上电，检测BMS，选择系统的启动方式，如果BMS为高电平，则系统从片内ROM启动。AT91RM9200的ROM上电后被映射到了0x0和0x100000处，在这两个地址处都可以访问到ROM。由于9200的ROM中固化了一个BOOTLOAER程序。所以PC从0X0处开始执行这个BOOTLOAER(准确的说应该是一级BOOTLOADER)。这个BOOTLOER依 ...

单片机编程  关于PCB封装的资料收集整理.pdf

关于PCB封装的资料收集整理. 大的来说,元件有插装和贴装.零件封装是指实际零件焊接到电路板时所指示的外观和焊点的位置。是纯粹的空间概念.因此不同的元件可共用同一零件封装，同种元件也可有不同的零件封装。像电阻，有传统的针插式，这种元件体积较大，电路板必须钻孔才能安置元件，完成钻孔后，插入元件，再过锡炉或喷锡 ...
