How to install 3.5-inch touchscreen driver for raspberry pie 3B

Raspberry pie 3B how to install 3.5-inch touch screen driver, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a simpler and easier way.

The 3.5-inch touch screen I bought is as follows:

Please correspond to hardware.

Hardware installation:

Turn off the raspberry pie, power it off, and plug the screen into the port corresponding to the raspberry pie.

Install the driver

Download the driver to / boot file

Method 1:

Insert the SD card into your computer, then download this file and put it in the root directory of the SD card.

Raspberry pie LCD driver: 171219, suitable for 2017-03-02-raspbian-jessie and later versions of Raspbian.

So the file is located in the / boot directory

Method 2:

On raspberry pie, change to the / boot directory

Then download it directly to the local area using wget

Cd / bootsudo wget www.waveshare.net/w/upload/9/99/LCD-show-171219.tar.gz

Method 3:

An article mentioned that there are also driver files on git, which can be downloaded using git at https://github.com/goodtft/LCD-show

You can use:

Cd / bootsudo git https://github.com/goodtft/LCD-show.git

I didn't try this method because of the network problem. In theory, the latest drivers can be obtained.

Make sure that after downloading to the / boot directory, switch to / boot

Cd / boottar xzvf / boot/LCD-show-171219.tar.gzcd LCD-show/chmod + x LCD35-show./LCD35-show

If you download it through the git method, there is no need for tar decompression.

How to use it:

LCD/HDMI handoff

Cd LCD-show executes sudo. / LCD-hdmi

Cd LCD-show executes sudo. / LCD35-show

After installing the touch driver, you can change the rotation direction of the screen by running the following command.

§rotate 0 degrees:

1. Cd LCD-show/

2.. / LCD35-show 0

§rotate 90 degrees:

1. Cd LCD-show/

2.. / LCD35-show 90

§rotate 180 degrees:

1. Cd LCD-show/

2.. / LCD35-show 180

§rotate 270 degrees:

1. Cd LCD-show/

2.. / LCD35-show 270

Restart is generally OK, if there is a problem, try to restart under the power outage.

Possible problems:

When the driver decompresses, an error may be reported, as if the error does not affect the use.

At first, I found the driver somewhere else, which is basically similar to this one. After installation, I found that the display was fine, the touch did not work, and the x and y axes were upside down. Go to Yuexue's official website to find the driver, install it, and it's OK.
