Part Number: TM4C123GH6PM

Hello guys,

I am using TM4C123GH6PM controller for my application.

I want to read data points stored in text file from pen drive.

Basically data points are the x,y and z coordinates of 3D object file.

Here I am using ucb_dev_bulk.c example and with the help of this i am able to create text file in

pen drive. But i am not able to read text file stored in pendrive. 

Any help of above matter would be helpful.

Sample program would be of great help.

Thanks in advance.
