driver quickly hacked together from a chinese sourcecode that came
|
||||
with the board and existing ili9320 code by Chris van Dongen (sjaak)
|
||||
(sjaak2002 at msn.com)
|
||||
|
||||
Also added rotation for 180 and 270 degrees and minor tweaks to
|
||||
setcursor
|
||||
|
||||
Added code comes without warranty and free bugs. Feel free to use
|

To use this driver:
|
||||
|
||||
1. Add in your halconf.h:
|
||||
a) #define GFX_USE_GDISP TRUE
|
||||
|
||||
b) Any optional high level driver defines (see gdisp.h) eg: GDISP_NEED_MULTITHREAD
|
||||
|
||||
d) If you are not using a known board then create a gdisp_lld_board.h file
|
||||
and ensure it is on your include path.
|
||||
Use the gdisp_lld_board_example.h file as a basis.
|
||||
Currently known boards are:
|
||||
HY_STM32_100p
|
||||
|
||||
2. To your makefile add the following lines:
|
||||
include $(GFXLIB)/drivers/gdisp/ILI9325/gdisp_lld.mk
