Hold button handiling - A nudge in the right direction? :)

(1/1)

motionman95:
I'm trying to add some extra lines of code to what the hold button does (I'm not making a plugin) - but I can't seem to find the RockBox file that handles that. I looked at this thread:

http://forums.rockbox.org/index.php?topic=12900.0

But that file seems like the improper place to put my code, if I'm right.
What file does RockBox use to handle the Hold button?

Its handled by the button driver for each target.  The file in that thread is for the e200.

motionman95:
I found the proper file, (button-c200) and added this:


--- Quote ---/*At the top of the file I included plugin.h*/
if(button_hold){
static const char filename[] = PLUGIN_APPS_DIR "/RockLock.rock";
plugin_load((char*)filename, NULL);
}

--- End quote ---

Instead of launching the plugin when I move the hold button, it splashes the message "Loading..." then freezes. What's wrong?

If you've added this code to 'firmware/target/arm/sandisk/sansa-c200/button-c200.c' (you don't clearly state which file): that's totally incorrect.

At first you should understand the separation between firmware/ and apps/: firmware/ code should *never* call any apps/ code, only the opposite is allowed.

If I would be you, I would try adding this code to apps/main.c or apps/root_menu.c (and replace button_hold with button_hold(), button_hold isn't declared globally).

edit:
apps/main.c already has something you want: AUTOROCK.

motionman95:
In that case, what function in main.c should I put my code? I don't want to use AUTOROCK because I don't need I to start every time I start my player, only when I switch on the hold button.
