From e1147b87abef7687055c9127437e6ce1353c6113 Mon Sep 17 00:00:00 2001 From: Tom Ross Date: Mon, 30 Jul 2007 05:19:05 +0000 Subject: RTC (real time clock) support for Rockboy. The time in games like Pokemon Gold/Silver should now stay synced on RTC-capable targets. Other targets will lose track of time when the player is turned off. User's can edit the .rtc file in an attempt to resync the RTC. The clock should stay synced when entering and leaving the menu. I've tested this over the past two weeks and it seems to work well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14071 a1c6a512-1295-4272-9138-f99709370657 --- apps/plugin.c | 3 +++ apps/plugin.h | 7 ++++-- apps/plugins/rockboy/Makefile | 3 ++- apps/plugins/rockboy/emu.c | 10 +------- apps/plugins/rockboy/menu.c | 12 ++++++++++ apps/plugins/rockboy/rtc.c | 49 ++++++++++++++++++++++---------------- apps/plugins/rockboy/sys_rockbox.c | 20 ---------------- 7 files changed, 51 insertions(+), 53 deletions(-) diff --git a/apps/plugin.c b/apps/plugin.c index dbd7d7b4fb..fee3a51851 100644 --- a/apps/plugin.c +++ b/apps/plugin.c @@ -439,6 +439,9 @@ static const struct plugin_api rockbox_api = { kbd_input, get_time, set_time, +#if CONFIG_RTC + mktime, +#endif plugin_get_buffer, plugin_get_audio_buffer, plugin_tsr, diff --git a/apps/plugin.h b/apps/plugin.h index 5ec0174c52..5146e18139 100644 --- a/apps/plugin.h +++ b/apps/plugin.h @@ -112,12 +112,12 @@ #define PLUGIN_MAGIC 0x526F634B /* RocK */ /* increase this every time the api struct changes */ -#define PLUGIN_API_VERSION 67 +#define PLUGIN_API_VERSION 68 /* update this to latest version if a change to the api struct breaks backwards compatibility (and please take the opportunity to sort in any new function which are "waiting" at the end of the function table) */ -#define PLUGIN_MIN_API_VERSION 65 +#define PLUGIN_MIN_API_VERSION 68 /* plugin return codes */ enum plugin_status { @@ -549,6 +549,9 @@ struct plugin_api { int (*kbd_input)(char* buffer, int buflen);
