Hey Martin, hey shabaz

In the first place, thank you so much for sharing this increadible useful information!

I've been through many unsuccessful attempts interfacing a SD card with the MSP432 during the last couple of weeks and finally got it working [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-a55e0243-c6ae-469e-80c5-d4c9f53bd705/contentimage_5F00_1.png:16:16].

I'm so happy to use the Energia library instead having to spend days with the FatFS Elm-Chan approach.

It feels so much more intuitive and you can put your efforts in the particular field you're really interested in instead of writing bytes in memory.

@mohammed nabi:I tried 2 modules similar to yours, and it was driving me to despair! So maybe this can help:

What finally did the job for me was exchanging the SD-modules with a more expensive microSD module from Ardafruit.

I guess the lack of regulators on the low cost module causes the errors or it doesn't work at all.

I found that those low cost SD- card modules only come with resistors and the level shift to 3,3V .

The more expensive ones come with a 10+pin IC. (Ardafruit =16pin)

I hope that many others will find your blog as it seems Energia don't plan on support the SD example.

Cheers!

Good project.

Since this is a backlink from the 43oh forums posted by Martin V:

http://forum.43oh.com/topic/9309-interfacing-sd-card-with-msp432-launchpad/page-1#entry71047

there is a boosterPack available for SDCards. You may have to change the pinouts though based on the Launchpad you are using.

For non Energia users, here is an MSP432 project with an SDCard:

Hii [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05]
I have tried two different SD cards but the result is same

Hello [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05]

i used this sd card holder

and the pin out is

Description MSP432 SD card holder

CS P 5.0(J2-13) 7

MOSI P 4.6(J2-15) 9

CLK P 1.5(J1-7) 11

MISO P 1.7(J2-14) 13

VDD 3.3 3

GND GND 1

I am using a 2GB SD card

i used the library Shabaz had provided
I have changed the sketch file CS pin as 13 just like Martin has done ..

when i run the datalogger sketch file I find the follow error

when i run the cardinfo sketch file this is what i get

[View:/resized-image/__size/405x271/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-a55e0243-c6ae-469e-80c5-d4c9f53bd705/contentimage_5F00_180830.png:405:271]

Hi Martin,

Oh, that's awesome. Glad you managed to port it across with just a couple of changes!

Very nice that the Energia code is so portable across the different platforms.

I've had so little time recently : ( so didn't get a chance to build up a testbed in time.

Anyway, this is great, I'll add a link to the Tiva post so that your work can be referenced from there too.
