How to interface SD card with 8051?

[hm1622]

i am doing vehicle tracking system using GPS and GSM.for the passive tracking i need a memory device so i decide to use SD card for as a GPS data logger so i need to know how the interfacing done.so i need some C code  about it and circuit diagram.the data store in SD card in MS excel format.

Hi,

 

SD card can be interfaced to microcontroller using SPI communication & 8051 does not have built in SPI function to interface with SD Card, you need to create SPI function, which is little difficult & time consuming. Suggest you to switch to latest versions of 8051 based controllers which has built in SPI function & it would be easy for you to interface with SDcard. 

 

Basic Interface of SPI includes four pins –> MISO, MOSI, SCK & SS

 

ThanQ

Amrith is right,

You better choose a bit more advanced mcu that have built in SPI module. Otherwise you have to write code to simulate such a module. If you can try with 8051, then lot of help available in the internet.

I suggest you to give a try, its very interesting and challenging.
