TM4C1294 ethernet and sd card with 'enet_lwip'

Alex Lo

I am trying to send a webpage using TM4c1294 from my sd card based on the example project 'enet_lwip'. To be honest i don't quite understand Javascript and web based programming in details. The problem i faced is that i don't understand how the tiva will go to my sd card and open the webpage (based on what is written in the description of 'enet_lwip') this is because from what i see, is that the webpage is obtain from 'enet_fsdata.h' which is using 'makefsfile utility' to generate the c code from 'fs folder'. If that is the case then how would the launchpad actually project a webpage from my sd card? I hope for some guidance in this area

Hello Alex,

Over-simplifying...

1. Why don't you convert the files for the webpage using the makefsfile and store the same in a sd card
2. Based on the user input fetch the relevant data to the address pointed by the variable in memory.
3. To read the sd_card use the sd_card example with FATFS.

Ya i know i could do so, but i would like to eventually do a data logging with the SD card and display it in the webpage, which is why i would like to know other possible method in displaying webpage from sd card

Hello Alex

None of my existing code repositories are well tuned to your requirement. May be invest time and effort to use the code base to do the same, would be my suggestion.
