Interfacing SD Card With MSP430Gx2xx

Mallappa T said:

I refer one Texas Instruments Datasheet(sdcard_appnote_foust_3.pdf) on SD Card Interfacing

Please give the full link - so that we can see what you're referring to.

Note that's an "Application Note" - not a "datasheet".

i can't find that pin outs in MSp430G2452 and 2553,Please

What do you mean by that?

This is where you need to study the Datasheets for those chips!

Send me about the SD Card connecting with MSP430

You said you already have a document "about the SD Card connecting with MSP430"?!

How do i Interface SD card with MSP430 ?

Exactly the same way that you'd interface it to any other microcontroller!

The SD Card neither knows nor cares what microcontroller you use.

I wrote an extensive post summarising the very large amount of information about SD-Cards already available on this forum and the wider internet. Unfortunately, the recent forum reorganisation has broken all my links and I can't seem to find it any more!

:-(

Therefore, I'm afraid you'll have to do your own forum & internet searches.

General - how to interface anything to anything else: http://bit.ly/pWAASo

2. and another thing is They are given in  following  Image SS,MISO,MOSI and SCK I can't find this I/O pins in MSP430G2452 and MSP430G2553.

3. Iam Using MSP430 Microcontroller

Those are the "standard" SPI signal names, as used by Motorola (now Freescale) - who invented it.

It's not hard to find what they mean and, thus, relate them to other names used by other vendors:

The SD Card specification would also help you - see previous links...

Note that the forum automatically highlights the part number as a clickable link - click it, and it will take you to the Product Page for the part.

Right at the top of the Product Page are links to the Data Sheet and Family User's Guide

Search for "SPI" in the Data Sheet  - it tells you which pins perform SPI functions

The Family User's Guide has a section titled, "Universal Serial Communication Interface, SPI Mode" - it gives a detailed description of the pin functions for SPI mode.

On the 2452, there is no USCI module but an USI module. Here the pins are named SCLK, SDO (data out = SIMO in master mode) and SDI (data in = SOMI).

SS is a chip select signal and a plain GPIO pin, controlled by the MSP software. Any unused GPIO pin is fine.
