TM4C1294NCPDT: usb mass storage using SDcard

Anushka Parab21

Part Number: TM4C1294NCPDT

hello,

We are using tm4c1294 controller in this we have used SD card as data log (.csv and .txt files).

Now we like to expand application feature , We need to read this files without removing sd card from PCB. So we have plan to use USB as mass storage device. I have go through example code named as usb_dev_msc.

My requirement is to transfer SD card files in to usb mass storage drive so that user can directly see or copy this files without removing SD card.(similar usage like sdcard reader ).just plug in usb wire to pc and removable disk is pop up to PC and in this removable disk having all sdcard files.

So please guide us how to visible all SDcard files in USB mass storage device.

Please share us sample code .

Thank you

Hi Anushka,

The usb_dev_msc will be the example for you to start building the application you need. Th usb_dev_msc example uses the onboard memory (the MX66L51235F serial SPI flash) for the storage media for the mass storage device. We also have SD card example in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\dk-tm4c129x\sd_card that you can reference to combine both examples into a USB mass storage using SD card. We don't have a ready to use example as such in TivaWare, sorry.
