Hello Shabaz,

The stellarisiti forums have been merged into the 43oh forum. Could you change your link from the article to the following:

[Energia Library] Petit FatFS SD Card Library - TivaC / CC3XXX Energia Libraries - 43oh

It is under Software Implementation:

This was easy. An existing SD card implementation

Hello Shabaz,

I am using the same TM4C123GXL pad as you, but, instead of the SD card directly, I am trying to use Adafruit MicroSD breakout card. It doesn't see the card. In the CardInfo example code, I notice that chipselect is set to 32.

const int chipSelect = 32; //cs PIN

A little below, there is the mode for pin 10 as output:

pinMode(10, OUTPUT); // change this to 53 on a mega

However, looking at the pins_energia.h under the stellarpad variant (is that the correct one?), pin 32 corresponds to PD_7 which is the pin at J4-9. I assume I am doing something wrong, or looking in the wrong place, but can't figure it out. The pin at J1-8 would be pin 8, and corresponds to PA_5

Any assistance will be most appreciated.

Hello Shabaz,

My name is Twofur and I’m new to the posting to forums and getting help from open sources. I’m learning computer architecture and I’m at a stage of building a project with a micro-controller that collects data and store it on a SD card. I’m using a Tiva Launch pad just like yours and I’ve uploaded the code to the device and hooked up the device to the right pins. When I run the device and it initializing the SD card it says that it had a card failed, or not present even though it is been checked over many times to correctly wired(by your website instructions) and the pins are connected. Now when I used another person’s booster from 43oh and the code (yours), it works properly. What I wanted to ask, first was have you had this problem (I don’t think you did), and second is there a trick your using to get your card to work (like a unknown resistor I’m not seeing in the picture to the CD or is there something miss-wired). Any advice or suggestions to do something from your experience will be helpful to understanding why this is not working. Also before I leave I wanted to thank you for your post and time you put into this program. It looks much cleaner then a lot of code I’ve seen for writing to SD card for other open source code and look easy to implement.

p.s. I forgot to put this in but I wanted to ask where the ports are being init(). I’m new to energia and It’s been hard to follow the path the program takes to assign the ports to the device (I’ve seen a lot of code this week and not having a debugger to watch makes it hard to locate parts of code at times.) Thanks for this as well if you have time.

Thanks for this post [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05].. SD library works just great with CC3200 Launchpad and you have made my job easier for my project in sudden impact design challenge... otherwise I am using [This way for SD interfacing with CC3200 and it has many limitations...

Hi DAB,

Nice work and thank you for posting this! I have the Tiva C series as well and am trying to implement a wave file player that plays audio through a speaker. How hard would it be do you think to move from your project (writing to the sd card), to my project (reading from the sd card)?

I would think that the code you have provided has libraries that also include functions for reading from the SD card. I am thinking since energia is so much like arduino, maybe I could merge your code for my Tiva C series mcu and some other .wav player code for arduino? What would you do?

Thanks for your time,

Aaron

Great post.

I need to build a couple of these loggers for data collection.

Great project Shabaz - lots of potential uses. It wasn't too long ago that this level of functionality took a considerable effort to implement.

Does this SD library use FAT32? (PC compatible files)
