这里是我的项目上的 SD 卡 (microSD) 的接口。microSD 卡可提供非常便宜现今，有一个巨大的记忆在任何大的选项嵌入系统项目。这是与 SPI 总线兼容的所以接口是很容易。SD 卡适配器也容易获得在市场中，一个可以轻松地一个面包板适配器通过焊接上它的几个针脚。下面的数字显示 SD 卡了的针脚 & 面包板适配器设计通过焊接 7-针突围 microSD 适配器上的标头。我已开始此项目具有 1 GB microSD 卡从晟碟 (稍后测试与超越卡也)。微控制器是 AVR ATmega8 或 ATmega32 运行在 8 Mhz 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

ISP for STR73X 默认情况下, bank0 是映射到地址0x00. 考虑到,IAP程序需存储在bank1,而用户程序需存储在bank0. 因此须使用CAPS工具,将bank1映射到地址0x00. 另外, 在IAP程序运行期间,必须在执行用户程序跳转之前,通过程序将bank0重映射到地址0x00(注:IAP程序已经实现了bank0重映射到地址0x00,用户不需要自己来编写代码).-ISP for STR73X default, bank0 is mapped to address 0x00. Taking into account, IAP process is stored in the bank1, while the user program to be stored in bank0. It is necessary to use the CAPS tool bank1 mapped to address 0x00. In addition, IAP procedure during operation must be in the implementation of user program before Jump through the procedure will bank0 re-mapped to address 0x00 (Note: IAP program has achieved bank0 re-mapped to address 0x00, the user does not need to write their own code).
