SDSDHC Card Interfacing with ATmega. FAT3. 2 implementation. Here is my project on interfacing of SD Card micro. SD. micro. SD cards are available very cheap nowadays, a great option for having a huge memory in any embedded system project. It is compatible with SPI bus, so the interfacing is easy. SD card adapters are also easily available in market, one can easily make a bread board adapter by soldering few pins on it. Following figures show the SD card pin out the bread board adapter design by soldering 7 pins of a breakout header on the micro. SD adapter Click on images for larger view. I had started this project with 1.

We focus on its usage with PIC16F series of MCUs. Small, fluidfilled bags known as minibags have been in short supply for years. Now, hospitals are feeling even more compromised from the. GB micro. SD card from San. Disk later on tested with transcend cards also. The microcontroller is AVR ATmega. ATmega. 32 running at 8. Mhz internal clock. MAX2. 32 is used to interface the circuit with PC for monitoring the data. FastShip is an easytouse, yet powerful program for designing hulls, superstructures, appendages, and other marine structures, with the ability to design. A 3. 3v supply is used for powering the mega.

The aim of this project was to learn interfacing of SD card and to understand the data transfer in raw format as well as in FAT3. I started with raw data transfer, sending some data to any block of the micro. SD, reading a block of it, reading and writing multiple blocks, erasing multiple blocks. All this in raw format. I used RS2. 32 for viewing the data read by microcontroller from SD card. The uc sends the data to Hyper. Terminal. Similarly, to write data to card, the data was fed thru Hyper. Terminal, by typing some text. Once raw data transfer achieved, I formatted the card with windows. XP FAT3. 2 and loaded it with some text files, directories and other files all stored in root directory of the card. After that I wrote the FAT3. Hyper. Terminal again, finding the totalfree memory of card. All this data is sent to Hyper. Terminal by the uc. Following is the Hyper. Terminal window showing different options Options 0 to 4 are low level functions dealing with raw data. If you use option 0, 1 or 3, you may have to reformat the card before using the FAT3. Erases selected number of blocks strating from selected block. Writes data to specified SD block address. Data to be entered in Hyper. Terminal using PC keyboard. Readss data of specified SD block address. Data is displayed on Hyper. Terminal window. 3. Writes selected number of blocks strating from selected block. Reads selected number of blocks strating from selected block. Here, the multiple block functions related to options 3 4 are disabled due to memory constraint as that time mega. FAT3. 2 testing. While testing with mega. FATTESTINGONLY defined in SDroutines. Options 5 to 9 are related to FAT3. Only short file names are supported right now, 8byte name3bytes extension. If you store a long name file in SD, it will be displayed by these routines in short name format only. For testing these options, format the card with FAT3. Hyper. Terminal. Displays list of available directories and files with size in the root directory of the card6 Reads a specified file and displays the file contents on Hyper. Terminal. 7 CreateAppend file with specified name, enter text from Hyper. Terminal. 8 Deletes any existing file with specified name. Displays total free memory of the card using FSinfo sector of the SD cardFollowing figures show the Hyper. Terminal window when options 5 9 are selected These figures show menu from Ver. Menu style is changed from Ver2. Note Hyper. Terminal is used here at 1. No parity, Flow Control none. This project needs very few components and can be done easily at home.
