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/plugins/plasma.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) (limited to 'apps/plugins/plasma.c') diff --git a/apps/plugins/plasma.c b/apps/plugins/plasma.c index 9e2e3832a3..f944d3d775 100644 --- a/apps/plugins/plasma.c +++ b/apps/plugins/plasma.c @@ -36,6 +36,8 @@ /******************************* Globals ***********************************/ +static fb_data *lcd_fb; + static unsigned char wave_array[256]; /* Pre calculated wave array */ #ifdef HAVE_LCD_COLOR @@ -201,9 +203,9 @@ int main(void) #ifdef HAVE_LCD_COLOR shades_generate(time++); /* dynamically */ #if defined(HAVE_LCD_MODES) && (HAVE_LCD_MODES & LCD_MODE_PAL256) - ptr = (unsigned char*)*rb->lcd_framebuffer; + ptr = (unsigned char*)lcd_fb; #else - ptr = *rb->lcd_framebuffer; + ptr = lcd_fb; #endif #else @@ -237,7 +239,7 @@ int main(void) p4-=sp4; #ifdef HAVE_LCD_COLOR #if defined(HAVE_LCD_MODES) && (HAVE_LCD_MODES & LCD_MODE_PAL256) - rb->lcd_blit_pal256( (unsigned char*)*rb->lcd_framebuffer, + rb->lcd_blit_pal256( (unsigned char*)lcd_fb, 0,0,0,0,LCD_WIDTH,LCD_HEIGHT); #else rb->lcd_update(); @@ -326,5 +328,8 @@ enum plugin_status plugin_start(const void* parameter) #if defined(HAVE_LCD_MODES) && (HAVE_LCD_MODES & LCD_MODE_PAL256) rb->lcd_set_mode(LCD_MODE_PAL256); #endif + struct viewport *vp_main = rb->lcd_set_viewport(NULL); + lcd_fb = vp_main->buffer->fb_ptr; + return main(); } -- cgit v1.2.3
