Hi Marco,

Sounds good! I’m interested in this. Would it be possible for you to post a 
complete patch?

Thanks,
Ben

The ADC in the LM3S series was also seriously spec'ed down in an errata. 
Extremely high offset values if I remember correctly.

We have been seriously let down by TI regarding the LM3S series, so we're not 
designing in any cpu’s from them. Mainly using ST and NXP for new designs now.

Yes, same thing. Cortex M3 vs M4 core is the main difference. TI ran into 
manufacturing problems with the LM3S series and developed the TM4C as a 
successor. TI stopped support for Stellarisware for the LM3S series and then 
renamed/forked it to TivaWare (or some such) for the TM4C chips. In the 
beginning it was more or less compatible, but I believe (!) it has diverged 
quite a bit now.

LM3S series is NRND, and I wouldn’t touch the TM4C series with a ten feet pole 
because of that. But we have a couple of designs with an LM3S8938 that I’d like 
to update to get access to the latest lwIP features.

Definitely interested. But if anybody has already done some work on it, please 
let us know.

[lwip-users] Port to Stellarisware

[Ben Stuyts]

Hi,

TI’s Stellarisware library for the LM3S series chips uses lwIP v1.3.1. By any 
chance, has anybody ported lwIP v2.0.3 to Stellarisware?

They basically #include all the lwIP *.c files into a single lwiplib.c file and 
compile that. Also not sure if their own interface/porting layer code is 
compatible with v2.0.3.

Thanks,
Ben

I am going to upgrade an old project which uses the original http server in 
contrib. I like the changes you made in your version. Is the second beta on 
your site still the most current one?

Thanks Simon, that is good to know. I'll have a go at enabling it.

For SSI/CGI there are lots of examples in TI's StellarisWare libraries 
fortunately. Although it takes some effort to follow what's handled where...

[lwip-users] LWIP_HTTPD_FS_ASYNC_READ, LWIP_HTTPD_DYNAMIC_FILE_READ

[Ben Stuyts]

Hi all,

While browsing the httpd sources I came across the LWIP_HTTPD_FS_ASYNC_READ and 
LWIP_HTTPD_DYNAMIC_FILE_READ define. In fs.h I read for 
LWIP_HTTPD_FS_ASYNC_READ: support asynchronous read operations (fs_read_async 
returns FS_READ_DELAYED and calls a callback when finished). And for 
LWIP_HTTPD_DYNAMIC_FILE_READ: support fs_read() to dynamically read file data. 
Without this (default=off), only one-block files are supported, and the 
contents must be ready after fs_open().

This sounds like something I could use to soften the ram requirements on my 
http server when serving pages from a serial flash chip. Currently I'm copying 
all open files into ram.

I looked for examples or log messages (in git) on how to use these feature, but 
couldn't find any information. Google doesn't turn up anything either. So my 
first question is: has this been tested and is it working? And the second 
question: are there any examples?

Thanks!
Ben

[lwip-users] http authentication

[Ben Stuyts]

Hi,

I need basic access authentication for the http server. I was thinking along 
the lines of rfc1945 chapter 11. Has any work on this been done? Otherwise I 
might give it a try.
