在前面帖子的安装了SDK，下面基于SDK创建图形界面应用程序。
创建工程目录
- mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/stm32mp1-openstlinux-23.06.21
- mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/stm32mp1-openstlinux-23.06.21/sources
创建程序目录
- mkdir $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/stm32mp1-openstlinux-23.06.21/sources/gtk_hello_world_example
- cd $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/stm32mp1-openstlinux-23.06.21/sources/gtk_hello_world_example
- #include <gtk/gtk.h>
- static void
- print_hello (GtkWidget *widget,
- gpointer data)
- {
- g_print ("Hello World\n");
- }
- static void
- activate (GtkApplication *app,
- gpointer user_data)
- {
- GtkWidget *window;
- GtkWidget *button;
- GtkWidget *button_box;
- window = gtk_application_window_new (app);
- gtk_window_set_title (GTK_WINDOW (window), "Window");
- gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);
- button_box = gtk_button_box_new (GTK_ORIENTATION_HORIZONTAL);
- gtk_container_add (GTK_CONTAINER (window), button_box);
- button = gtk_button_new_with_label ("Hello World");
- g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
- g_signal_connect_swapped (button, "clicked", G_CALLBACK (gtk_widget_destroy), window);
- gtk_container_add (GTK_CONTAINER (button_box), button);
- gtk_widget_show_all (window);
- }
- int
- main (int argc,
- char **argv)
- {
- GtkApplication *app;
- int status;
- app = gtk_application_new ("org.gtk.example", G_APPLICATION_DEFAULT_FLAGS);
- g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
- status = g_application_run (G_APPLICATION (app), argc, argv);
- g_object_unref (app);
- return status;
- }
创建Makefile脚本
- PROG = gtk_hello_world
- SRCS = gtk_hello_world.c
- CLEANFILES = $(PROG)
- # Add / change option in CFLAGS and LDFLAGS
- CFLAGS += -Wall $(shell pkg-config --cflags gtk+-3.0)
- LDFLAGS += $(shell pkg-config --libs gtk+-3.0)
- all: $(PROG)
- $(PROG): $(SRCS)
- $(CC) -o $[url=home.php?mod=space&uid=72445]@[/url] $^ $(CFLAGS) $(LDFLAGS)
- clean:
- rm -f $(CLEANFILES) $(patsubst %.c,%.o, $(SRCS))
网线连接板卡，复制可执行程序到板卡，其中192.168.1.4是板卡的IP。
- scp gtk_hello_world root@192.168.1.4:/usr/local
在板卡上执行程序
- cd /usr/local/
- su -l weston -c "/usr/local/gtk_hello_world"
效果
点击按钮后，界面消失，终端打印Hello World
总结：ST提供的SDK十分完善，开发应用十分方便。
