Ledcontrol in Sd card

[jmcastillejo]

I run the webbino server on a stm32 bluepill with an sdcard, but I can not get server requests to work. it works if I use flash storage, but not when I use storage on sdcard.

In the example ledcontrol the function ledToggle is called from this line:
const Page page01 PROGMEM = {index_html_name, index_html, index_html_len, ledToggle};

how do I call that function when I use sdcard storage?

Thank you

This is not supported at the moment, if I remember correctly. Functions can only be associated to pages stored in flash.

I am currently away, I will check better when I'm home, in a week or so.

A workaround is to make the following variable public instead of private
byte ethernetBuffer[MAX_URL_LEN + 16];
In WIZ5x00.h (or the interface you use) .
Then you can parse the GET request line yourself

Uhm, and where do you do that?

I don't think any hacks are necessary, this should be pretty straightforward to do with the last code refactoring I did. I will have a look at it ASAP.

[jmcastillejo]

Thanks for your work, it's a great project

This should be done with 3c51945, please check out the current master branch, test it and report.

See the LedControl example for the new method of associating functions to pages, this should work across all backends.

Hello!!

I have tested the modifications and it still does not work using the sd card, only work with flash

[SukkoPera]

A quick test I did works instead. Can you please post your sketch?

@jmcastillejo: Make sure to associate the function with FileFuncAssoc rather than with FlashFileFuncAssoc as shown in the current LedControl version.

[jmcastillejo]

if I change the FlashFileFuncAssoc function by FileFuncAssoc I get the following error:

src / WebbinoCore / WebServer.h: 101: 60: note: in definition of macro 'FileFuncAssoc'

             const char REPTAG_FFA_VAR (var) [] PROGMEM = path; \

exit status 1
initializer fails to determine size of '_ffa_indexAss'

[SukkoPera]

Try something like:

FileFuncAssoc (indexAss, "/index.htm", indexFunc);

[jmcastillejo]

With that it compiles well, it executes the function in the http request but the tags do not work, and in the chrome the save window appears as when entering the url. This is the sketch:

#include <Webbino.h>
#include <WebbinoInterfaces/WIZ5x00.h>

const byte ledPin = 1;
const byte LED_ACTIVE_LEVEL = HIGH;
boolean ledState = false;
const uint8_t SD_CS = PB12;   // chip select for sd

// Instantiate the WebServer and page storage
WebServer webserver;

SdStorage sdStorage;
