Date: Wed, 31 Mar 2004 18:33:57 +0200 Hi all I finally succeeded in connecting a sony head unit to a pic16f84a with the gnunilink software (gnunilink.sourceforge.net) Now I would like it to comunicate with the archos. I know I am not the only one wanting to do that. However I've had a look in rockbox source, and it seems not easy to interact with the mpeg and the status. I could not find any work for a tight integration between the mp3 and an external device. Could anyone show me a pointer to some work that has already been done? The actual remote control stuff is polled! Is there a problem implementing a non blocking interrupt handler? I need to implement it as interrupt because the archos should respond in a limited time to gnunilink requests. What I propose is simple: - actions are communicated from the interrupt handler to the firmware through a queue to avoid critical sections. - status are memory mapped. just need some small infos: - disc name (folder name) - track name - time no need for a mutex or something... for the action queue i propose to use the button queue. navigation could be done through standard archos behaviour just by mapping some specific head unit actions into some archos buttons... For the status, it would be the same, except that the head unit has 8 characters. the display is also polled by the gnunilink, so there will be latency between actions and the display. talkbox could help... any comments welcome... _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-03-31 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
