显示与触摸

MIPI DSI 接口

硬件连接

MIPI_DSI 将MIPI显示屏按照图示通过FPC排线连接到开发板的MIPI接口。 确保显示屏的供电和信号线连接正确。

MIPI屏显示测试

开发板上电启动,即可在 MIPI 屏看到如下界面。

MIPI_DSI_2

背光测试

执行如下命令,通过修改亮度级数改变屏幕亮度。

root@linaro-alip:/# echo 1 > /sys/class/backlight/backlight/brightness
root@linaro-alip:/# echo 255 > /sys/class/backlight/backlight/brightness

HDMI 接口

开发板的HDMI接口为标准HDMI,可热插拔自适应分辨率

桌面切换分辨率

  • 打开系统设置,找到 Display

HDMI

  • 点击 Resolution 切换不同分辨率

HDMI_2

命令行切换不同分辨率

  • xrandr -q 参数来查看你的屏幕目前支持的分辨率的情况
root@linaro-alip:/# xrandr -q
Screen 0: minimum 320 x 200, current 2640 x 1280, maximum 16384 x 16384

   720x400       70.08
  • xrandr -s 0 命令来将屏幕恢复到原来的分辨率

  • xrandr -s 指定屏幕的分辨率大小

例如:

xrandr -s 1280x800

触摸屏

开发板上有一组I2C的TP接口,默认触摸IC驱动为gt911

硬件连接

连接如下图所示:

TP

滑动或点击屏幕测试是否能正常使用
