软件环境:Win7,Keil MDK 4.72a, IAR EWARM 7.2, GCC 4.2,Python 2.7 ,SCons 2.3.2
硬件环境:Armfly STM32F103ZE-EK v3.0开发板

上篇文章中我们LCD驱动进行了移植,接下来进行编译和调试
【1】在命令行中使用scons编译,出现“命令太长”的错误
看到Link时命令行太长的错误,如下图。
参考文章修正scons编译时armlink链接错误的解决办法:
(1) 使用Notepad++打开C:\Python27\Lib\site-packages\scons-2.3.2\SCons\Platform\__init__.py,定位到205行,修改如下代码:
prefix = env.subst(‘$TEMPFILEPREFIX‘)
if not prefix:
#prefix = ‘@‘
prefix = ‘ ‘
修改后保存。
(2)使用Notepad++打开stm32f103ze-ek/Sconstruct文件,定位到27行附近,如入如下代码:
if rtconfig.PLATFORM == ‘iar‘:
env.Replace(CCCOM = [‘$CC $CCFLAGS $CPPFLAGS $_CPPDEFFLAGS $_CPPINCFLAGS -o $TARGET $SOURCES‘])
env.Replace(ARFLAGS = [‘‘])
env.Replace(LINKCOM = [‘$LINK $SOURCES $LINKFLAGS -o $TARGET --map project.map‘])
if rtconfig.PLATFORM == ‘armcc‘:
env["TEMPFILE"] = SCons.Platform.TempFileMunge
# env["LINKCOM"] = "${TEMPFILE(‘$LINK -o $TARGET $SOURCES‘)}"
env["LINKCOM"] = "$LINK -o $TARGET $LINKFLAGS ${TEMPFILE(‘--via $SOURCES‘)}"
env["TEMPFILEPREFIX"] = ‘ ‘ # arm tool chain
Export(‘RTT_ROOT‘)
Export(‘rtconfig‘)
... ...
修改完成后保存。
然后重新scons编译,结果如下:
【2】RTGUI运行测试
将编译生成的代码下载到开发板中,复位运行,终端中显示如下:

很显然,挂载的根目录下面根本没有/resource/hzk16.fnt文件,所以报错,因为字库占空间较大,所以目前还无法支持汉字功能。打开rtconfig.h文件,定位到173行附近,注释掉RTGUI_USING_FONTHZ定义,修改如下:
/* SECTION: RT-Thread/GUI */
#define RT_USING_RTGUI
/* name length of RTGUI object */
#define RTGUI_NAME_MAX 12
/* support 16 weight font */
#define RTGUI_USING_FONT16
/* support Chinese font */
//#define RTGUI_USING_FONTHZ
/* use DFS as file interface */
#define RTGUI_USING_DFS_FILERW
/* use font file as Chinese font */
#define RTGUI_USING_HZ_FILE
/* use Chinese bitmap font */
#define RTGUI_USING_HZ_BMP
/* use small size in RTGUI */
#define RTGUI_USING_SMALL_SIZE
调试跟踪发现,在执行_graphic_driver_vmode_init()时,导致init进程崩溃,跟进这个函数,发现在执行rt_memset()时导致init进程崩溃。打开rtgui/server/driver.c,定位到46行附近,注释掉rt_memset()这个函数,代码修改如下:
static void _graphic_driver_vmode_init(void) { if (_vfb_driver.width != _driver.width || _vfb_driver.height != _driver.height) { if (_vfb_driver.framebuffer != RT_NULL) rtgui_free((void*)_vfb_driver.framebuffer); _vfb_driver.device = RT_NULL; _vfb_driver.pixel_format = RTGUI_VFB_PIXEL_FMT; _vfb_driver.bits_per_pixel = rtgui_color_get_bits(RTGUI_VFB_PIXEL_FMT); _vfb_driver.width = _driver.width; _vfb_driver.height = _driver.height; _vfb_driver.pitch = _driver.width * _UI_BITBYTES(_vfb_driver.bits_per_pixel); _vfb_driver.framebuffer = rtgui_malloc(_vfb_driver.height * _vfb_driver.pitch); //rt_memset(_vfb_driver.framebuffer, 0, _vfb_driver.height * _vfb_driver.pitch); _vfb_driver.ext_ops = RT_NULL; _vfb_driver.ops = rtgui_framebuffer_get_ops(_vfb_driver.pixel_format); } }
修改后保存,重新编译下载,复位运行,此时终端显示

信息显示rtgui线程处于挂起状态,下面将加载一些Demo程序进行测试。
【3】加入RTGUI Demo例程
(1)将github网站的RTGUI-Master/demo/examples复制到rt-thread-1.2.2/components/rtgui目录下,然后在命令行运行scons --tartget=mdk4 -s,重新打开工程后可以看到gui-examples组已经加入进来,如下图:
(2)打开application.c,定位到129行附近,加入gui_appplication_init(),修改如下:
... ...
#ifdef RT_USING_RTGUI
{
extern void rt_hw_lcd_init();
extern void rtgui_touch_hw_init(void);
extern void gui_application_init(void);
rt_device_t lcd;
/* init lcd */
rt_hw_lcd_init();
... ...
#ifdef RTGUI_USING_CALIBRATION
calibration_set_restore(cali_setup);
calibration_set_after(cali_store);
calibration_init();
#endif /* #ifdef RTGUI_USING_CALIBRATION */
gui_application_init();
}
#endif /* RT_USING_RTGUI */
(3)打开gui_examples工作组下dem_application.c,定位到129行附近,代码修改如下:
void gui_application_init(void)
{
static rt_bool_t inited = RT_FALSE;
if (inited == RT_FALSE) /*避免重复初始化 */
{
rt_thread_t tid;
tid = rt_thread_create("wb",
gui_application_entry, RT_NULL,
2048 * 2, 25, 10);
if (tid != RT_NULL)
rt_thread_startup(tid);
inited = RT_TRUE;
}
}
#ifdef RT_USING_FINSH
#include <finsh.h>
void gui_application()
{
gui_application_init();
}
/* finsh 终端可以执行gui_appplication() 命令运行上面函数*/
FINSH_FUNCTION_EXPORT(gui_application,
gui application demo)
#endif
然后再定位到31行附近,将gui_appliction线程入口的名字改过来,修改如下:
... ...
struct rtgui_win *main_win;
static void gui_application_entry(void *parameter)
{
struct rtgui_app *app;
struct rtgui_rect rect;
app = rtgui_app_create("gui_demo");
if (app == RT_NULL)
return;
... ...
然后定位到64行到120附近代码,从demo_view_box()开始,直到rtgui_win_show()之间的代码除了留下demo_view_button() ,其它代码注释掉,修改如下:
<pre name="code" class="cpp">rtgui_container_add_child(RTGUI_CONTAINER(main_win), RTGUI_WIDGET(the_notebook)); //demo_view_box(); /* 初始化各个例子的视图 */ /* demo_view_benchmark(); demo_view_dc(); #ifdef RTGUI_USING_TTF demo_view_ttf(); #endif #ifndef RTGUI_USING_SMALL_SIZE demo_view_dc_buffer(); #endif //demo_view_animation(); #ifndef RTGUI_USING_SMALL_SIZE demo_view_instrument_panel(); #endif //demo_view_buffer_animation(); demo_view_window(); demo_view_label(); */ demo_view_button(); /* demo_view_checkbox(); demo_view_progressbar(); demo_view_scrollbar(); demo_view_radiobox(); demo_view_textbox(); demo_view_listbox(); demo_view_menu(); demo_view_listctrl(); demo_view_combobox(); demo_view_slider(); demo_view_notebook(); demo_view_mywidget(); demo_plot(); demo_view_digtube(); #if defined(RTGUI_USING_DFS_FILERW) demo_view_edit(); //demo_view_bmp(); #endif #if defined(RTGUI_USING_DFS_FILERW) demo_fn_view(); #endif #if 0 #if defined(RTGUI_USING_DFS_FILERW) demo_view_image(); #endif #ifdef RT_USING_MODULE #if defined(RTGUI_USING_DFS_FILERW) demo_view_module(); #endif #endif demo_listview_view(); demo_listview_icon_view(); #endif */ rtgui_win_show(main_win, RT_FALSE);
然后保存,重新scons编译,下载到开发板上,可以看到如下效果:
由于拍摄的原因,实际可左边的四个按钮的前景色应该分别是红色、蓝色、灰色和灰色,是但实际上没有显示出来。而RTGUI默认的背景色是灰色,到此可以基本说明,LCD底层启动可以正常工作了,余下的问题留待后面解决。
