From 3237ae4a4ff9296a377ff9194a11038da161208f Mon Sep 17 00:00:00 2001 From: William Wilgus Date: Wed, 7 Oct 2020 02:01:35 -0400 Subject: LCD core move buf ptr and address look up function viewport struct I'm currently running up against the limitations of the lcd_draw functions I want these functions to be able to be used on any size buffer not just buffers with a stride matching the underlying device [DONE] allow the framebuffer to be decoupled from the device framebuffer [DONE need examples] allow for some simple blit like transformations [DONE] remove the device framebuffer from the plugin api [DONE}ditto remote framebuffer [DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr while remote lcds may compile (and work in the sim) its not been tested on targets [FIXED] backdrops need work to be screen agnostic [FIXED] screen statusbar is not being combined into the main viewport correctly yet [FIXED] screen elements are displayed incorrectly after switch to void* [FIXED] core didn't restore proper viewport on splash etc. [NEEDS TESTING] remote lcd garbled data [FIXED] osd lib garbled screen on bmp_part [FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport [FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer [FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw) [UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear scrolling viewports no longer trigger wps refresh also fixed a bug where guisyncyesno was displaying and then disappearing [ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes (LCD_ and LCD_REMOTE_) LCD_STRIDE(w, h) same as STRIDE_MAIN LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH) test_viewports.c has an example of usage [FIXED!!] 2bit targets don't respect non-native strides [FIXED] Few define snags Change-Id: I0d04c3834e464eca84a5a715743a297a0cefd0af --- apps/gui/statusbar.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'apps/gui/statusbar.c') diff --git a/apps/gui/statusbar.c b/apps/gui/statusbar.c index cf70b7bb39..708624b23e 100644 --- a/apps/gui/statusbar.c +++ b/apps/gui/statusbar.c @@ -183,6 +183,7 @@ static void gui_statusbar_init(struct gui_statusbar * bar) void gui_statusbar_draw(struct gui_statusbar * bar, bool force_redraw, struct viewport *vp) { struct screen * display = bar->display; + struct viewport *last_vp = NULL; if (!display) return; @@ -267,7 +268,7 @@ void gui_statusbar_draw(struct gui_statusbar * bar, bool force_redraw, struct vi #endif memcmp(&(bar->info), &(bar->lastinfo), sizeof(struct status_info))) { - display->set_viewport(vp); + last_vp = display->set_viewport(vp); display->set_drawmode(DRMODE_SOLID|DRMODE_INVERSEVID); display->fill_viewport(); display->set_drawmode(DRMODE_SOLID); @@ -343,7 +344,7 @@ void gui_statusbar_draw(struct gui_statusbar * bar, bool force_redraw, struct vi gui_statusbar_led(display); #endif display->update_viewport(); - display->set_viewport(NULL); + display->set_viewport(last_vp); bar->lastinfo = bar->info; } } -- cgit v1.2.3
