PICtail™ Daughter Board for SD™ and MMC Cards
Overview
The PICtail Daughter Board for SD and MMC Cards is a demonstration board for evaluating reading and writing data on
SD or MMC cards. It is an expansion board compatible with a number of PICDEM™ demonstration boards. A complete
list of compatible PICDEM demonstration boards is available on Microchip’s web site.
Note: The implementation and use of the FAT file system, SD card specifications, MMC card specifications and other
third party tools may require a license from various entities, including, but not limited to Microsoft
Card Association and MMCA. It is your responsibility to obtain more information regarding any applicable licensing
obligations. Some third party web sites have been listed in “References” for your convenience.
Getting Started
To get started, a compatible PICDEM demonstration board is required. In general, a board is compatible if it has a
PICtail Daughter Board interface expansion port or a PICtail Plus board interface expansion port. Most PICDEM
demonstration boards do not have the female PICtail Daughter Board header installed, so a 14x2 female connector is
included with this kit for the user to install onto the PICDEM demonstration board if necessary. When connecting this
daughter board to a board with the PICtail Plus connector, like the Explorer 16 Development Board, the connector
should be inserted in the first slot of the demonstration board (aligned with Pin #1) to communicate using the SPI1
module, or in the second slot of the demonstration board (aligned with Pin #33) to communicate using the SPI2
module. Note that the pins used for other signals will change as well, depending on the slot selected.
Features
• Supports a wide range of SD cards
• Supports auto-triggering of files on SD cards
• Operates on a wide range of voltages from 3.3V-5.0V DC
• Includes PICtail Daughter Board and PICtail Plus Board connection interfaces
• Compatible with many boards with PICtail Daughter Board and PICtail Plus interface, including Explorer 16
Board Configurations
A total of 7 jumper locations are available. As shipped from the factory, some of the jumper locations are bridged by
circuit traces forming a default setup. To change this, the user will need to cut the traces and install pins and a block
jumper. Afterward, the features can be enabled or disabled easily by installing or removing the jumper.
Note: Jumpers, JP1-JP6, are only used to configure pin settings for the PICtail Daughter Board connector. To switch
between sets of operating pins on a PICtail Plus header, the card edge connector must be swapped between the first
and second slot of the PICtail Plus socket. Jumper, JP7, is also used only by the PICtail Daughter Board connector.
Firmware
USB mass storage examples can be downloaded from http://www.microchip.com/usb. USB products will require a
vendor ID and product ID. For more information, consult Application Note, AN1189 (DS01189). Application Note,
AN1045 (DS01045), provides a method for interfacing directly to SD cards formatted with a FAT file system. It can be
downloaded from:
