PicTail Plus扩展板上的SD/MMC卡在哪里插入

HiTe依赖于你正在适应它的董事会。就我几年前所能想到的，我发现了一些关于如何将它连接到我的Pic18 Explorer在Microchip网站上的文档。可能在卡相关文档中。如果你没有找到它，我保证你可以在PICTHED卡上查看PIN功能，并将它与你连接的板上的电路相匹配。如果有一个软件演示，该代码可能会给你一些关于PIC引脚在与卡的通信中使用的提示。还检查SD/MMC主题的任何应用笔记。

    Hi
 
That depends on the board you are adapting it to.
As far as I can remenber from a few years ago, I found some documentation on how to connect it to my PIC18 Explorer in the Microchip website. Probably on the card related documentation.
 
If you don't find it, I sugest youi look at the pin functions on the pictail card and mate it with the circuitry on the board you are connecting it to. If there is a software demo, the code might give you some hints on what PIC pins are used in the comunication with the card. Also check for any application notes on the SD/MMC subject.

我终于找到了扩展板的示意图，并跟踪线通过PIC引脚。图中所示的取向对于“SPI2”是正确的，并且可以追溯到预期的微PIN。NB。扩展板原理图上的CD和WD（引脚60和62 RESP）都是LabelDelp90，但在Explorer板上是P90和P89（USB）。



      以下为原文

    I eventually found the Expansion board schematic and traced the lines through to the PIC pins. The orientation shown in the picture is correct for 'SPI2' and is traceable back to the expected micro pins.
NB. CD and WD (pin 60 and 62 resp') on the expansion board schematic are both labelled P90 but back at the Explorer board they are P90 and P89 (USB). 

不要相信照片里的照片，因为这是S/C的力量。SD适配器应该是其他方式，卡片阅读器面对Excel 16／32。

    Don't trust the way I have it in the photo because this s/c the power. SD adaptor should be other way around, card reader facing the Explorer16/32.

HIIS这是你所创立的HTTP://WW1.MICCHIP.COM/DIXBOSS/En/DeVICECDOC/DS-51583B.PDFU卡应该连接到最后一页中的“卡边缘连接器”图。您可以使用PIC引脚指定（RB2/RG9，RF6/RG6，…）和电源线来调整它的位置。在PICTHOP PLUS和Explorer之间使用扩展卡，而不是映射整个路径。顺便问一下，你使用的是Explorer吗？HyHube关于JurrGE

    Hi
 
Is this what you have found
http://ww1.microchip.com/downloads/en/DeviceDoc/DS-51583b.pdf
 
Your card should be connecetd acording to the "card edge connector" diagram in the last page.
You can use the PIC pins designations (RB2/RG9, RF6/RG6, ....) and the power lines to adjust its position.
 
If you are using an expansion card between the pictail plus and the explorer, than you have to map  the whole path.
 
By the way wich explorer are you using?

HioOK一看PICTHOP PLUS扩展板，这个“P90”的东西在我看来是一个打印错误。PIN号是相同的，但是信号的名称是不同的。考虑到Explorer 16／32.比较PICTHEL PLUS扩展和SD/MMC PICTUM的图表，我想说的是PIN编号。SD/MMC卡的边缘连接器（J2）与扩展板（J62）的引脚数相匹配。我似乎是1-1，2-2，…，30-30。除了PIN号之外，还有与每个引脚相关的信号的匹配。不要忘记在Explorer和扩展上标记的大多数信号。N板只是指征。它们的可用性取决于浏览器中的微安装。例如，那些USB信号，如果PIC没有USB硬件，这些线路将是别的东西。而且大多数都是由简单的数字I/O来处理的，所以它们可以被分配给PIC中的几乎任何一个引脚。就像在SD/MMC卡上的CD、WD和/CS一样，这些标签只是对探查器和扩展板如何布线的帮助/指导。例如，P54、P55和P56将根据使用的通信协议、SPI或I2C、MOSI、MISO和SCK的名称来更改其名称，用于SPI信令。但是，如果为I2C配置MSSP外设，那么相同的PIN将具有其他名称。

    Hi
 
Took a look at the pictail plus expansion board and this "P90" thing seems to me as a typo.
The pin number is the same but the signal names are different.
 
Considering the Explorer 16/32.
Comparing the diagrams of the pictail plus expansion and the SD/MMC pictail, I would say the pin numbering of the edge connector (J2) of the SD/MMC card matches the pin numbers of the expansion board (J62).
I seems to be a 1-1, 2-2, ...., 30-30. 
Besides the pin numbers, there is also a match on the signals associated with each pin.
 
Don't forget that most of the signals labeled on the explorer and on the expansion board are only indications. Their availability depends on the micro instaled in the explorer. For example those USB signals, if the PIC doesn't have USB hardware those lines will be something else.
Also most of them are handled by simple digital I/O, so they can be assigned to almost any pin in the PIC. Like the CD, WD and /CS on the SD/MMC card.
Those labels are only a help/guide on how the explorar and the expansion boards are wired.
 
For example, the P54, P55 and P56, will change its name acording to what communication protocols is in use, SPI or I2C. MOSI, MISO and SCK are names for SPI signaling, but if you configure the MSSP peripheral for I2C, the same pins will have other names.
