Working with Raspberry Pi

Hardware connection:

Prepare the components as shown below, here we will use Raspberry Pi 5 as the connection demonstration.

7EP-CAPLCD-details-5-1.jpg

Step 1: Connect the cables ①, ④ and ⑤ to the bottom panel of the screen as shown in the figure below.

7EP-CAPLCD-details-5-2.jpg

Step 2: Connect the other end of the cable ① to the LCD adapter (select ② or ③ depending on the model of the Raspberry Pi motherboard), and then plug the adapter into the Micro HDMI port of the Raspberry Pi.

Software settings:

Supports Raspberry Pi OS/Ubuntu/Kali and Retropie systems for Raspberry Pi.
When the LCD works on these systems, the resolution must be set manually, otherwise the display resolution will be incorrect, which will affect the experience.
If the system comes with a KMS driver that automatically identifies the resolution, you can skip this step.

1. Download the latest version of the image from the https://www.raspberrypi.com/software/operating-systems/ Raspberry Pi website
2. Download the compressed file to your PC, and extract it as .img file
3. Connect the TF card to the PC, format the TF card with SDFormatter software
4. Open the Win32DiskImager software, select the system image prepared in step 1, and click Write to burn the system image
5. After the image burning is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of the config.txt, save and safely eject the TF card

hdmi_group=2
hdmi_mode=87
hdmi_cvt 1280 800 60 6 0 0 0
hdmi_drive=1

6. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, wait for a few seconds and it will be displayed normally

Linux dimming

Use DDC/CI program, take the ddcutil tool as an example here. 

#Install the ddcutil tool:
sudo apt-get install ddcutil -y
#Detect support for DDC/CI display:
sudo ddcutil detect
#Adjust the brightness of the display, <value> needs to be changed to a value of 0-100
sudo ddcutil setvcp 10 <value>

For more information about the ddcutil function command, please visit: http://www.ddcutil.com/commands/

Working with PC

Supporting Windows 11/10/8.1/8/7 system. How to use:

1. Connect the Touch interface of the LCD to the USB interface of the PC, and Windows will automatically recognize the touch function.
2. Connect the HDMI interface of the LCD to the HDMI interface of the PC, and Windows will automatically recognize the display function.

  • Note:
  • Some PCs do not support HDMI devices plug and play, and can be used normally after restarting the system.
  • If the USB port is not powered enough, the LCD screen will flicker, and the LCD can be restored to normal use after connecting an external 5V 1A power adapter to the LCD's Power port.

Windows dimming

  • 1. Download and install the DDC/CI application, such as the open-source Twinkle Tray
  • 2. Open the software dimming icon, it will recognize the Waveshare display, and adjust the display backlight brightness by sliding the scrollbar.

Windows Specified Touch Screen

Take Windows 10 as an example:

  • 1.Go to Windows settings of the system, enter in the search bar and click on Calibrate the screen for pen or touch input (as shown in the figure below)

  • 2. In the pop-up Tablet PC Settings interface, click Setup

Win10 touch02.png

  • 3. The text prompt shown below will appear on the screen. Please click on the touchpad with your finger and the computer will recognize it as a touch screen.
Note: If the screen is blank, please press the Enter key, and the text prompt will switch the screen. (The screen corresponding to the text prompt will be used as a touch screen.)

FAQ

Question:I would like to know what the speakers are rated for (Watts and Ohms), but there are no markings printed on them. I would like to possibly upgrade the speakers for my application, but I need to know what kind of audio output the 7EP-CAPLCD has.

 Answer:

This screen has two audio output interfaces, namely the onboard 3.5mm headphone jack and the 4PIN speaker output (8Ω 2W Speaker).
