Hi,

Memory card needs SPI port which is not there in 8051

Hello,
Actually I have another version of 8051 of philips company, that supports spi communication.

i am not much sure but i will suggest first read the data sheet of your memory card (or any memory card)

how data can be stored

how data can be retrived from specific location

interfacing requirements like voltage level, current etc

everything first you need to know

rest is to implement the required protocol, handshake using program

it may be SPI or any other does not matter

Hi Jainam,

The memory card uses a command based protocol to communicate with devices. It should be connected to a controller which can send the commands to the memory card via SPI lines and then the controller to the PC port.

Hello alfred,

I have understood those commands ..
bt the doubt is like how to make it communicate with hyperterminal?

unlike gps and gsm module which i directly connected to hyperterminal without my controller..
so how to make my sd card communicate with the controller?
how will it take commands from my pc hyperterminal when i have my memory card interfaced with spis?
