您好！
是否有人告诉我如何 关闭用户 LED (GIOB_1和 GIOB_2 )
1.从驱动程序启用选项卡中启用 GIO 驱动程序； 2.从 PINMUX 选项卡中选中 GIOB 复选框(清除所有冲突(如果可用)； 3.从 GIO->Port B 选项卡将 GIOB[1]设置为输出； 4.从 GIO->Port B 选项卡中将 GIOB[2]设置为输出； 4.生成代码 5.在 CCS sys_main.c 中：包含 gio.h 6.在 main()中：调用 gioInit()； 7.在 main()中：
调用 gioToggleBit (gioPORTB、1)；切换 LED2 调用 gioToggleBit (gioPORTB、2)；以切换 LED3
调用 gioSetBit (gioPORTB、1、0)；将 LED2设置为关闭 调用 gioSetBit (gioPORTB、2、0)；将 LED3设置为关闭
