AT91SAM7X系ARM系统开发功能测试程序,如果你着手用AT91SAM来进行系统开发,这是确实是个很好的资料,有了他,会助你一臂之力.本源码是ADS1.2下的源码,用于IO口功能测试

at91sam9261控制器的IO口的基本控制代码,供参考-at91sam9261 IO control code, you can reference

An AT91SAM7 Serial-IO/UART and interrupt example for the Atmel AT91SAM7S64 (should work with all AT91SAM after minimal changes) which demonstrates UART interfacing (serial I/O), interrupt/exception-handling and lots of gcc-specials.
