2020-10-31lcd_framebuffer bugfixes, sanity checksWilliam Wilgus1-0/+3
several issues I saw that could pontentially cause problems scroll engine doesn't take text height into account when checking bounds NBELEMS was one whole row too large hopefully I got them right this time Change-Id: If303da8320429c3964fc675351cb088d46303745

2020-10-26LCD core move buf ptr and address look up function viewport structWilliam Wilgus1-46/+52
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

2012-03-20Refactor lcd_clear_viewport().Thomas Martitz1-50/+0
* Unify 16bit implementaitons (move to 16bit-common.c). * Add viewport clipping (within #ifdef HAVE_VIEWPORT_CLIP) like other lcd_* functions have. Change-Id: I4e96b2efdb94d2f7bc5bcdb710554117989579ec
2012-02-28lcd drivers: Convert lcd_[remote_]framebuffer to a pointerJonathan Gordon1-9/+6
Change all lcd drivers to using a pointer to the static framebuffer instead of directly accessing the static array. This will let us later do fun things like dynamic framebuffer sizes (RaaA) or ability to use different buffers for different layers (dynamic skin backdrops!)

simulator check is also added to set_viewport that will show an error/note when DEBUGF is enabled. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23551 a1c6a512-1295-4272-9138-f99709370657
2009-10-20Convert lcd_activation callbacks to use the event system to allow for ↵Thomas Martitz1-21/+0
multiple parallel callbacks (for custom statusbar). Increase maximum event count as we need more (I actually had a report about it during custom statusbar testing).
