Description
技术领域
本发明涉及一种快闪存储卡***的方法及装置,特别是检测判断一种快闪存储卡类型的方法及装置。
背景技术
闪存拥有DRAM可直接用电流来更改数据,以及ROM在电源关闭后数据可储存的特性,加上无线行动多媒体信息逐渐普及化,许多新兴产品如数字相机、PDA、大哥大、MP3播放装置等,正好需要如快闪存储卡这样具有体积小、容量大、读写快速、省电、耐震等优点的可携带式内存。而快闪存储卡跟其它可携带的储存媒介如磁盘片和光盘片比较,磁盘片容量太小、体积太大、易损害,光盘片不耐震也较耗电,于是快闪存储卡逐渐成为可携带式记忆装置的主流产品,不过快闪存储卡目前规格不统一,可区分为五种:CF卡(Compact FlashCard)、SM卡(Smart Media Card)、SD卡(Secure Digital Card)、MMC卡(Multi Media Card)和MS卡(Memory Stick),各种规格的快闪存储卡皆有世界级的大厂商带头组织协会生产,因此各有各的支持厂商成员,目前各规格也都达到一定的规模而互不相让,短期之内是不容易有整合标准化的情况。在读取快闪存储卡方面,要支持单一规格的记忆卡技术并不难,但为满足各种规格的需求,必须要发展多合一的存取装置,以整合并读取大小不同规格及脚位数的快闪存储卡。
现有技术判断快闪存储卡类型与***的装置如图1所示,复数个快闪存储卡插槽被包含在快闪存储卡接口100,该些各个快闪存储卡插槽可以对应到至少两个以上的快闪存储卡,也可以对应到至少两种不同类型的快闪存储卡。该些各个快闪存储卡插槽脚位的各个导线110分别连接到控制模块120,该导线110用以传送信号到控制模块120,控制模块120依据该些信号判断哪一个插槽被***快闪存储卡,并且存取该快闪存储卡的数据,当快闪存储卡接口100所包含的快闪存储卡插槽数越多,连接到控制模块120的该些导线数也随着增加,所需成本以及体积也跟着增加。
发明内容
本发明目的,在于可提供一种检测判断快闪存储卡类型与***的方法和装置,可以检测到快闪存储卡的***与否,并能判别快闪存储卡的类型与***的数量,适用于多卡合一的快闪存储卡的装置,其中不同快闪存储卡插槽的脚位的导线是相连接的。
本发明提供一种检测判断快闪存储卡类型与***的方法,包括检测连接到多数快闪存储卡插槽脚位的多数导线的信号变化,该些导线可分为检测导线以及信号导线,检测导线个别连接到各个一快闪存储卡插槽的脚位导线,而信号导线则连接到所有该些快闪存储卡插槽的脚位导线,该信号导线以一对多的方式连接到该些快闪存储卡插槽脚位导线;以及根据该些检测导线上的信号来判断***的至少一快闪存储卡。
本发明提供一种检测判断快闪存储卡类型与***的装置,至少包含一快闪存储卡接口,该接口有复数个快闪存储卡插槽;一控制模块,用以检测从该些快闪存储卡插槽传送过来的信号;以及一信号导线,一端同时与所有该些快闪存储卡插槽连接,且另一端与该控制模块连接。

具体实施方式
为使能够更进一步了解本发明特征及技术内容,请参阅以下有关本发明的详细说明与附图,然而所附图式和以下详细说明仅供参考用,并非用来对本发明加以限制。
请参阅图2,其附图为本发明一最佳实施例的一种检测快闪存储卡***类型的装置图,包括一快闪存储卡接口200,一控制模块220及一总线210,其中快闪存储卡接口200包含有至少两个以上的快闪存储卡插槽201~20n,该些快闪存储卡插槽可以对应到至少两种不同类型的快闪存储卡,也可以对应到至少两个以上的快闪存储卡;控制模块210用以对快闪存储卡插槽传送过来的信号做检测;以及一总线220,包含个别连接各个快闪存储卡插槽的脚位导线的多数检测导线以及连接到所有该些快闪存储卡插槽的脚位导线的单一信号导线,该信号导线以一对多的方式连接到该些快闪存储卡插槽的脚位导线;该些快闪存储卡插槽的脚位导线可以先在该快闪存储卡接口200里相连成一体,再与该信号导线相连接,该些快闪存储卡插槽的脚位导线更可以在该快闪存储卡接口200外相连接成一体,再与该信号导线相连接,请参阅图3。前者的连接方式由于在该快闪存储卡接口200内先将该快闪存储卡插槽多数的信号导线相连接,再以一条导线的方式跟控制模块连接,可以节省许多的成本耗费,后者由于是将该快闪存储卡插槽多数的信号导线延续到快闪存储卡接口200外再相连接,该快闪存储卡接口200与往昔的快闪存储卡接口内部所包含的插槽以及插槽导线装置可以兼容,因此可以利用该往昔的快闪存储卡接口,将该插槽脚位导线的信号导线拉出该快闪存储卡接口外部,再予以连接成一条导线;上述两种连接方式皆各有优点,可选用二者之一实施。
上述的快闪存储卡插槽201~20n。在本实施例中,该些插槽可以设计为五种快闪存储卡分别一一对应到五个插槽于快闪存储卡接口,该五种快闪存储卡为CF卡、SM卡、SD卡、MMC卡以及MS卡,此五种快闪存储卡的插槽脚位导线,更为了减小面积和节省成本为考量,将五种快闪存储卡插槽传输数据用的脚位导线相连接在一起,此各种快闪存储卡插槽脚位导线连接的情况,请参阅图4,如图4序号3,表示为快闪存储卡插槽第三脚位导线的接线状况:SD/MMC卡的脚位SDD1、CF卡的脚位CFD2和SM卡的脚位SMD4其与插槽导线相连接。
上述相连接的脚位导线是各个快闪存储卡插槽传输数据用的脚位导线,而该些快闪存储卡插槽的非传输数据的脚位导线如检测脚位导线以及致能脚位导线,不与任何导线相连接,直接连结到控制模块,该检测脚位导线以及该致能脚位导线若与该其它任何传输数据的导线连接,当第一快闪存储卡正在存取数据,该数据会使用共同连接的导线来传输,若是正好有第二快闪存储卡***插槽,该插槽的检测脚位导线的信号传送到控制模块,也是使用该与传输数据共同连接的导线,容易造成信号传输的混乱,所以将该检测导线以及该致能导线设计为直接连结到控制模块,控制模块使某一快闪存储卡致能以后,再进行数据的存取。
上述的控制模块210,在检测从该些快闪存储卡插槽传送过来的信号,根据信号判断***的快闪存储卡,本实施例五种快闪存储卡相对应的检测与判断情况如下:
根据脚位CFCD0_和脚位CFCD1_变为低电位,判断为CF卡***;
根据脚位SMCD_变为低电位,判断为SM卡***;
根据脚位SDD3_CD变为高电位或脚位SDCD变为低电位,判断为SD卡***;
根据脚位SDCD变为低电位,判断为MMC卡***;以及
根据脚位MSINS变为低电位,判断为MS卡***。
请参阅图5,其附图为本发明执行一种判断快闪存储卡类型与***的方法步骤的流程图,包括有下列步骤:
步骤31:检测信号的变化,该信号来自于快闪存储卡插槽的特定脚位;
步骤32:判断快闪存储卡***的类型,该判断方式是根据信号的变化;
步骤33:判断是否***超过一种快闪存储卡?
若是,跳至步骤34;
若否,跳至步骤35;
步骤34:提供警示讯息给使用者,使用者必须选择一快闪存储卡来使用;
步骤35:执行其对应的快闪存储卡的类型程序,开始存取快闪存储卡数据;
因此本发明提供一种判断快闪存储卡类型和***的检测方法,特别适用于使用多卡合一的快闪存储卡读取装置,控制模块检测连接到快闪存储卡插槽脚位多数导线的信号变化,根据信号的变化,可以判断快闪存储卡的***以及类型,并去对照各快闪存储卡相对应的脚位变化的数据库,此方法更具有一警示使用者的功能,若一次***超过一种快闪存储卡,将会出现警示信息给使用者,告知使用者请选择一种快闪存储卡使用,并可再告知使用者拔除其余非选择使用的快闪存储卡,若只***一种的快闪存储卡,则开始执行其快闪存储卡对应的类型的快闪存储卡程序。
以上所述,仅为本发明一些最佳具体实施例的详细说明与图标,惟本发明的特征并不局限于此,任何熟悉该技艺者在本发明的领域内,可轻易及的变化或修饰皆可涵盖在所述本案的专利范围内。
