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  Emulating a synchronous serial

The C500 microcontroller family usually provides only one on-chip synchronous serialchannel (SSC). If a second SSC is required, an emulation of the missing interface mayhelp to avoid an external hardware solution with additional electronic components.The solution presented in this paper and in the a ...
