3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.
Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.
However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.
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 recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.
Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.
After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.
( " XXX-show " can be changed to the corresponding driver, and " 90 " can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees)

I"m in a project of a gameboy advance with a Orange pi inside. I found a 3d file of a case on web and I"m editing it, but I was stuck with the screen. I need a 2.8 to 3.2 inches screen, but those available at aliexpress and eBay wouldn"t fit because of the breakout board width. I found some bare lcds but was in doubt if it was a good idea using it, plugging it somehow with the Opi. I saw some FFC FPC connectors and I"m wondering if it"s work. Can I use them to do the same as you did or it doesn"t work for that? Any tips for the number of pins the screen and the connectors must have? I found a nice screen but it"s 18 pins, and the closest I could find was a 20 pins connector. Will it work the same or it has to have exactly the same number of pins?
Also: is there any other kind of screen I could use like that plugging on the gpio, but something quite like a plug and play stuff, I mean, something that doesn"t need any coding? Sorry for the many questions, I"m still a learner so there are still a lot of doubts lol btw, thanks by now, mate
This application note is part 1 of our 2 part TFT LCD screen series. Part 1 discusses configuring the screen resolution of a TFT with a Raspberry Pi. Part 2 discusses calibrating the touch screen of a TFT. Click here to read part 2.
This application note discusses how to setup a TFT touch screen display with Raspberry Pi. The display chosen for this project is a 7-inch LCD with a capacitive touch feature. The display has 1024x600 pixels of resolution and when calibrated for the Raspberry Pi can display 16.7M colors. With a few changes to the Raspberry Pi configuration files the dimensions of this display can be matched for perfect resolution.
The display in this project is easy to interface with the Raspberry Pi because it has an LVDS to HDMI backpack adapter connected. This makes it simple to connect an HDMI cable between the two devices and begin your project. In a few steps any display can be configured for optimal resolution. Additionally, this display has a capacitive touch screen which can be calibrated through Raspberry Pi for accuracy. These features combined with the large size of the display make it a great choice for a variety of Raspberry Pi projects.
Connecting the TFT to the Raspberry Pi is simple and only requires a few steps. The display has a HDMI connection backpack interfaced with the device so there is no need for soldering or individual pin connections. If you have used Raspberry Pi before, you will notice that the connection to the TFT is standard and straightforward. Before powering the Raspberry Pi you should make all the necessary connections to the screen. Plug in the HDMI. Connect the CTP port with a micro-USB cable. Power the screen with micro-USB cable connected to a USB port on the Raspberry Pi or a power adapter that provides 5V. You only need three connections to the HDMI backpack module on the TFT.
You will need a mouse and keyboard to setup the Raspberry Pi before the touch screen is enabled. You will also need a micro SD card with Noobs loaded onto it before powering. (Installing NOOBS) Lastly you will need an ethernet cable to setup internet to download or update the software. Once you power the Raspberry Pi, Noobs will give you some options of what software platform you want to install. For this project I chose Raspbian (recommended option). (Installing Raspbian) After installation you will likely notice that the graphics are distorted or that the width and height of the screen are not the desired dimensions. This is because Raspberry Pi’s auto-calibrate feature doesn’t recognize this display. So, to get the best picture, we will need to calibrate it manually.
If it’s not terrible, and you can still see what you’re doing on the display, you can do this through Terminal. We want to edit the “config.txt” which loads from the boot file. The other option is to remove the SD card and load the file on the computer or setup SSH and edit the file remotely.
The file will open in a text editor called nano. We need to add the specifics of our display to the file by adding the following commands to the file:
The last three fields of hdmi_cvt can be omitted, and they will refer to the default values. The other commands declare the use of HDMI and create a new mode for the hdmi_cvt specifications. For detailed information on these commands and others that function in the config.txt file refer to the Raspberry Pi documentation website.
If the screen is still not perfectly configured for the device, a few other tweaks can be made to the config.txt file. Adjust the overscan parameters to add or remove pixels on the edges. For example, adding 33 pixels to the “overscan_right” parameter corrects overflow of the image on the right side of the screen. This takes a few trial and error attempts to perfect.
If you notice that turning safe mode off results in a blank screen you could have a bad HDMI connection. First try another HDMI cable. If this does not fix the problem, then we can increase the signal strength of the HDMI by editing the config_hdmi_boost command in the config.txt file. The standard setting in the configuration file is set as:
This default value is 2 and can be increased up to 11 if necessary. Try adding this command at increased increments until the issue is solved. You will need to edit the config.txt file on your computer or remotely for this step.
With only a few changes to the Raspberry Pi’s default configuration file the TFT can become compatible with the Raspberry Pi. This display is a great choice for interfacing with the Raspberry Pi because it has an HDMI connection type which makes for any easy setup. After the resolution and is set to a desired value we can now optimize the touch feature of the display. See here for more information on how to further calibrate this display.

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.
Once this LCD is enabled, meanwhile the default settings for HDMI are changed. If you want to use another HDMI monitor, please run the following command:cd LCD-show/
This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the CD image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually withsudo apt-get install -y xinput-calibrator
After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.Doing dynamic recalibration:
5. Execute commands as below. Note that you need to use "Pi " user permission instead of root to execute this commandnano ~/.config/lxpanel/LXDE-pi/panels/panel
8. reboot your Raspberry Pi. If the virtual keyboard is installed correctly, you can find that there is a keyboard icon on the left of the barsudo reboot
Rotating the screen to the proper orientation proved challenging. The config.txt rotate commands don’t work with the raspberry pi4. I couldn’t get the xorg configuration to rotate the display. When I added kernel commandline parameters to rotate the display, that worked for the initial verbose boot screen… but once KlipperScreen loaded, it was the wrong orientation.
I ended up having to modify the init function in screen.py as below, but it’s pretty hacky. Not sure if there’s a better way on a raspberry pi 4. But… it works
