Step 2: Visit the link below, download the Etcher software. Step 1: Visit the home page of the Raspberry Pi by following the link below to download the Raspbian Buster. Mic, speaker (if integrated Google Assistant).1 LCD screen or TV (the size is equal to or smaller than the size of Acrylic glass, can be purchased for savings).1 wooden frame (whatever size you want).1 HDMI cable to connect it to the TV or LCD monitor.1 Raspberry Pi 3 B + (with power, shell, heatsink, memory card, fan.turning it into a similar tool to Google Home mini to control the device, ask questions and do some other tasks. With Magic Mirror, you can integrate into it Google Assistant Vietnamese or Home Assistant. In this project, we will use open source software MagicMirror by MichMich installed on Raspberry Pi 3, then via HDMI to export to the screen and finally apply a 2-dimensional Acrylic glass on the front screen. So, we need to fix this.The following article will guide you to turn an ordinary mirror into a smart mirror (Magic Mirror) that can both mirror and display general information. See from the following… When I use the stylus to touch the screen, the stylus goes hay-wired. The other thing I found something wrong is, the touch screen is not callibrated at all! So, you still be able to revert all changes. Not to worry, simply go to the iMac to SSH into your RP4. When the screen is hung, it looks like this. Changing it to /dev/fb1 will hang the screen. Some will work, some won’t.ĭon’t do the following. Next, let’s try to see if we can optimize a bit here and there. You can actually try a few so that it is correct for you. So, all you need is to go to Preference -> Raspberry Pi Configuration -> Display Tab -> Set Resolution to “CEA mode 4 1280×720 60Hz 16:9”. Something that I did not mentioned, is the default installation script will change the screen resolution to very very low resolution. So that you can run the correct installation scripts. This is what the config.txt file should look like for the last few lines.įor you guys, if you bought the 3.5 inch screen, in general, it should work, but you should know which one you bought. No problem.Īnd now, the orientation of the screen is correctly done. So, the stupid case has the USB-C and mini HDMI on one side. (sorry, I have to place it upside down like that. So, once you install this, and I can see my small 3.5″ is rebooted correctly. I suspect this has something to do with the frame buffer interface. So, you have to read thru and try and error. Seems like a lot of people are angry with the issue that it does not work. Unfortunately, for me, HDMI working fine, but the small 3.5″ screen still give a blank white screen. It will reboot to the correct HDMI screen.īut if you also connect the RP4 to HDMI, then, by right both screen should appear. This will correctly set the launch code to use specific screen. As you can see, when you boot up the RP4, the 3.5 inch screen is blank white. But you can write simple GUI that can touch the button for your program. And since it is a touch screen, you can use a sylus with the screen.īut trust me, the screen is too small for anything. Won’t make a lot of diff, but at least there is a fan there. The new RP4 runs at much high speed, and produce a lot of heat. Remember we asked why there is a fan there? This is how you fit the the screen onto the RP4. This is the nice casing I bought from Amazon. But I know it can work with the LCD driver from MHS as the chipsets used is the same. Why I know? Because there is no MHS word there. The other day, I bought a LCD screen for my RP4. I will also share what went wrong, and what is correct too. May be the best way is to document down how I did what, did everything on my RP4 (Raspberry Pi 4).
