问题描述

我有一个 waveshare 3.5 英寸触摸式 LCD 显示器，我正在尝试让它与最新版本的 Raspbian A.K.A Raspbian Jessie 一起使用.我按照 futurice.com 的教程来让它工作(教程的标题是我想在我的 pi 上安装一些 LCD)并且它在 Raspbian Wheezy 上工作得很好.我现在得到的只是一个空白的白色屏幕.非常感谢所有帮助！(我必须使用来自 Raspberry pi 网站的没有 NOOBS 的官方 Raspbian Jessie 图像.)我有一个 Raspberry Pi 2 Mobel B +.

I have a waveshare 3.5 inch touch LCD display and I m trying to get it working with the latest version of Raspbian A.K.A Raspbian Jessie. I followed futurice.com 's tutorial on getting it to work (tutorial is titled I'd like some LCD on my pi) and it worked on Raspbian Wheezy just fine. All I get now is a blank white screen. All help is greatly appreciated! (I must use the official Raspbian Jessie image without NOOBS from the Raspberry pi website.) I have a Raspberry Pi 2 Mobel B +.

推荐答案

来自产品页面:

为什么 LCD 不能与我的 Raspbian 一起使用?要将 LCD 与树莓派官方镜像，需要先安装驱动.请请参阅用户手册.但是，对于第一次测试，您可能需要直接使用我们提供的图像.为什么液晶屏还是不行使用 Waveshare 提供的图像? 确保硬件连接是正确的并且连接良好.确保TF卡中的图像被烧毁正确.PWR 会一直亮着，ACT 会一直闪烁.Raspberry Pi 成功启动，以防两个 LED 都亮起继续，可能是图像被错误地烧毁或TF卡接触不良.我应该使用哪种电源?它是强烈建议使用独立的 5V/2A 电源适配器，因为PC 的 USB 端口可能没有足够的电量来支持 Pi和液晶显示器.欲了解更多信息，请查看维基页面

Why the LCD doesn't work with my Raspbian? To use the LCD with the Raspberry Pi official image, driver should be installed first. Please refer to the user manual. However, for the first testing, you may want to use our provided image directly. Why the LCD still doesn't work with the Waveshare provided image? Make sure the hardware connection is correct and connects fine. Make sure the image in TF card is burnt correctly. The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact. Which power supply should I use? It is strongly recommended to use a stand-alone 5V/2A power adapter, because the PC's USB port might doesn't have enough power to support the Pi and LCD.

听起来您要么需要使用他们的 Raspian 映像，要么在现有的 Raspian 安装上安装此显示器的驱动程序:

It sounds like you either need to use their Raspian image, or install the driver for this display on your existing Raspian install:

tar xvf LCD-show.tar.gz
cd LCD-show/
sudo ./LCD35-show
