KL27 USB MSD device application

Question asked by Juan Jose Vicente on Dec 2, 2016

Hi everyone,


I am currently designing a board based on a KL27 which will communicate via USB to an android tablet.
Based on the demo available in this article https://community.nxp.com/docs/DOC-105714,
I would like this board to act as MSD device which would create a file including some sensor values (these value will eventually change through time).

 

I haven´t work with the USB protocol yet. So, I will base my project on this demo.

 

Regarding the callback function, where should I create the file and how should I prevent the tablet to access to this file when I am updating it?

 

Thanks in advance,
Juanjo
