interface SD card with MSP430

Other Parts Discussed in Thread: MSP430G2553, MSP430F5529, MSP-TS430PN80USB

i'm a beginner in the world of MSP430, and i have to interface an MSP430 with a SD card. what is the specification my MSP430 need to have? on the TI website, i find an Application Report (SLAA281B – November 2005 – Revised March 2008) where they were using an MSP430F161x to do this interface?

1- is it the only model that can do it?

2- i bought the TI launchpad, can i use it to program all the family of MSP430 or is it only for the MSP430G2? or i can ask the question in this way: is the ti launchpad compatible with all the family of MSP430?

thank you,

    You need to study the SD-Card specification;  that will tell you what an SD-Card requires - then choose an MSP430 that can (at least) meet those requirements.

    That's the standard approach for any interfacing task: http://www.8052.com/forum/read/160143

    thanks for you advice, now know what i need,

    as  i read you can interface with an SD card in a SPI mode. i m using an MSP430G2553 which has an UART. is it possible to configure the UART in an SPI.mode?

    thanks

    Note how the forum automatically makes the part number -  MSP430G2553  - into a clickable link.

    Click that link, and it will take you to the Product Page

    On the product page, you will find full documentation and resources for the part, including:

    • A list of features - is SPI included?
    • A block diagram - spot the SPI?
    • The Datasheet - describes electrical & mechanical characteristics;
    • The Family User Guide - describes the capabilities & how to use all the features;
    • Example Code;
    • etc, etc, ...

    Not exactly. The users guide describes all features of all MSPs of a family. The datasheet specifies which features are available on a specific MSP of this family. Thisgoes beyond the features list on the product page.
    Strictly taken, these features are electrical characteristics, but this term is usually understood as I/O voltages and such.

    One should add that for finding example code or additional documentation, you might need to cloik on the 'read more' buttons that hide most of the available stuff.

    i ask a TI engeneer if i can use the TI launchpad with the other family of MSP430, and he answered  i couldn't.

    but if i bought an MSP430 F4794, how i can programm that? i  think i need a developpement board to programm any MCU. am I wrong?

    Partly. You don't need a development board. You need aboard with a JTAG connector. And an MSP-FET430UIF which can program any MSP430 microcontroller - not just the ones that are inteded to be used with an EZ430-xxx experimenters board (like the LaunchPad) with an integrated FET.

    thanks, that's what i want to use MSP430F55xx 80-Pin FET tool and target board combination. you have a target board and also a MSP-FET430UIF. the MSP430F5529 has 80 pin. so i think it's will work fine,

    Check for compatibility first. There are several 80 pin target boards. I think you'll need the MSP-TS430PN80USB taget board and not the PN80 or PN80A. Same 80pin package but different pinout.
