rockbox/firmware/drivers/lcd-color-common.c, branch master My Rockbox tree Fix dangerous casts 2017-02-04T16:24:47+00:00 Amaury Pouly amaury.pouly@gmail.com 2017-01-15T23:10:38+00:00 d7871914acd2ed77f43344e36e08944524a67d9e On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is not valid. In any case, one should use intptr_t and ptrdiff_t when casting to integers. This commit attempts to fix all instances reported by GCC. When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h Change-Id: I2273b0e8465d3c4689824717ed5afa5ed238a2dc

lcd-24bit: Introduce a 24-bit mid-level LCD driver 2014-06-20T22:15:53+00:00 Thomas Martitz kugel@rockbox.org 2014-06-18T05:15:00+00:00 a1842c04f9cb73210d4cacde61a9e4b115050765 With LCD driver all calculation will be performed on RGB888 and the hardware/OS can display from our 24bit framebuffer. It is not yet as performance optimized as the existing drivers but should be good enough.The vast number of small changes is due to the fact that fb_data can be a struct type now, while most of the code expected a scalar type. lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit it enforces the generic C code. All plugins are ported over. Except for rockpaint. It uses so much memory that it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

lcd-16bit: Split out some functions to lcd-color-common.c 2014-06-20T22:13:58+00:00 Thomas Martitz kugel@rockbox.org 2014-06-15T16:26:44+00:00 0250be1d6799db7b5ddc99cb33f31bf9cff01ed2 An upcoming lcd-24bit.c driver will re-use a lot of code from the 16bit drivers, so prepare for that.
