Posted on November 03, 2016 at 20:04Unfortunately you have a long way to go. The file window you are seeing is the mbed code loader . You will need some kind of file system built into your application. This might make more sense to use the on-board uSD card slot and install FatFS and try to get that working. Putting files in the on-chip flash program memory and then trying to read them out as ASCII HTML files is probably doable but non-trivial.
Once you get that going so that your application can read your web files off the SD card, you will need to modify the HTTP server code which is part of LWiP to use ascii files. Its default setup uses an external utility to convert HTML into data that is stored as ''C'' source code which is then linked directly into the application that contains LWiP. The LWiP server then responds to WEB requests by passing this re-formatted data out to the requesting party. So these routines would have to be modified to respond by reading from your SD card, non-reformatted data and just send it out.
It should be a fun project which I kinda intended to tackle but haven't had the time to spend on it. If you succeed it would be a nice tutorial to post if you get it working.
Good luck.
