摘要:
This application report and associated code implements the interfacing of Secure Digital (SD) or Multi-Media Card (MMC) types of Flash memory cards with the TMS320F28xxx digital signal controllers (DSCs). These cards can use serial peripheral interface (SPI) or parallel (SD) interface to connect to the host. This application report demonstrates the SPI mode and includes the schematics showing the interconnections and the software routines. This is basic driver software, providing basic functionality. You can add the SD/MMC commands and additional functions required per application. This document covers SD versions 1.10 and the new 2.00 specifications, meant for SD high capacity (SDHC) cards.
申请报告及相关的代码实现了接口的安全数字(SD )或多媒体卡(MMC)的使用TMS320F28xxx数字信号控制器(DSC)闪存卡类型。这些卡可以使用串行外设接口(SPI)或并行( SD )接口连接到主机。本应用报告表明SPI模式,包括原理图显示互连和软件例程。这是基本的驱动程序软件,提供基本的功能。您可以添加的SD / MMC命令和每个应用程序所需的附加功能。这份文件涵盖的SD 1.10版本和新的2.00规格, SD高容量( SDHC)存储卡的意思。
