Usage
When users connect the Raspberry Pi to use, they need to configure the official system. Or you can also burn the configured system image directly.
Tips:Basic for Raspbian Jessie with PIXEL (2017-04-10-raspbian-jessie.img)
Step 1:Download the Raspbian IMG
https://www.raspberrypi.org/downloads/raspbian/
Step 2: Burn the system image
If you don't know how to do that,you can refer to the Raspberry Pi office tutorial
Step 3: Open terminal and Download the driver on RPI
Run:
sudo rm -rf LCD-show git clone https://github.com/goodtft/LCD-show.git chmod -R 755 LCD-show cd LCD-show/ sudo ./LCD35-show
Wait A Few Minutes, when the system reboot ok, you can see that.
Touch screen calibration
- This LCD can be calibrated using a program called xinput_calibrator
- Install it with the commands:
cd Elecrow-LCD35
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb
- Click the Men button on the task bar, choose Preference -> Calibrate Touchscreen.
- Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.
- You can create a 99-calibration.conf file to save the touch parameters (not necessary if file exists).
/ect/X11/xorg.conf.d/99-calibration.conf
- Save the touch parameters (may differ depending on LCD) to 99-calibration.conf, as shown in the picture:
