Android Things：显示无法正常工作 [英] Android Things: display isn't working

问题描述

之前我曾将我的 RaspberryPi 与Waveshare LCD一起使用，并且已安装 Raspbian ，所以显示没有问题，但是现在我有了 Android Things SDK，那么如何使用它来进行显示呢？由于Waveshare为 Raspbian 操作系统提供了不同的映像，但是如何为 Android Things 操作系统获取驱动程序？

Earlier I was using my RaspberryPi with Waveshare LCD and Raspbian was installed so there was no issue with display, but now I have Android Things SDK so how can I get display working with it? As Waveshare was providing different image for Raspbian OS, but how to get its driver for Android Things OS?

我正在关注此和此，即可在raspberry-pi上安装。

I was following this and this for installation on raspberry-pi.

推荐答案

到目前为止， Android Things 图像尚未随附默认配置显示在 config.txt 文件中SD卡的根目录（请参阅引导分区）。该配置应手动添加。 在提供的文档或制造商的网站中查找合适的显示配置。

As of now Android Things image isn't shipped with a default configuration for display in config.txt file which is located in the root of your SD card (see the boot partition). The configuration should be added manually. Look for an appropriate display configuration in the supplied documentation or manufacturer's website.

例如，对于我来说， Waveshare 5inch 800x480 HDMI LCD（B） 以下行需要附加到 config.txt ：

For example, in my case for Waveshare 5inch 800x480 HDMI LCD (B) the following lines needed to be appended to config.txt:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

实际上， max_usb_current ， hdmi_group 和 hdmi_mode具有上述值的参数应适用于不同制造商的各种显示器。 hdmi_cvt 中的屏幕分辨率会有所不同。

In fact, the max_usb_current, hdmi_group and hdmi_mode parameters with the values above should work for a wide range of displays from different manufacturers. Screen resolution in hdmi_cvt will vary.
