Parameters

Electrical Specifications

•Note 1: Input voltages exceeding the maximum or improper operation may cause permanent damage to the device.
•Note 2: The input current needs to be ≥ 3A, otherwise it will cause the startup failure or display abnormality, and staying in an abnormal state for a long time may cause permanent damage to the device.
•Note 3: Please do not store the display panel in a high-temperature and high-humidity environment for a long time. The display panel should operate within its limits, otherwise it may be damaged.

Assembly Guide

If you purchase the all-in-one version (PI4-HMI-7A, PI5-HMI-7A), then there is no need to perform hardware assembly; you can use it directly after powering on.
The following are the hardware assembly steps for the PI5-HMI-7A:
Please prepare the following accessories:

1. Remove the HDMI expansion board and connect the 22Pin DSI cable (⑨) and 2Pin cable to the screen. (Note the direction of the gold finger of the DSI cable)

2. Re-secure the HDMI extension board with the screws.

3. Respectively install the thermal tapes (① and ②) and heatsink (⑤) on the front and back sides of Raspberry Pi 5, and insert the system card (③).

4. Connect the Raspberry Pi 5 motherboard to the HAT, make sure the mounting holes of the Raspberry Pi are aligned with the four screw holes on the back of the screen, and fix them with M2.5*4mm silver metal screws.

Use DSI cable (⑨) to connect DSI interface to CAM/DIPS 1 interface of Raspberry Pi.

6. Install the metal front panel (⑧), fix the silicon key (④) inside the case, and fix them with KM2.5*5mm black metal screws. And use M2.5*5mm black metal screws to fix the side cover.
(PI4 and PI5 front cover hole positions are inconsistent, please distinguish them.)

7. Finally, install the green terminal on the rear cover and complete the hardware assembly.

Software Settings

If you are using a pre-installed system card, you do not need to perform any software configuration. Insert the card and start the device. The default username is pi and the password is raspberry, which will allow you to directly enter the desktop environment.

Method 1: Flash Official Image

• 1. Connect the TF card to the PC, download and use Raspberry Pi Imager to flash the corresponding system image.

• 2. After the flashing is completed, find the config.txt file in the root directory of the TF card, open it and add the following code at the end of the file, save and eject the TF card safely.

Note: Since Pi5/CM5/CM4 has two mipi DSI interfaces, please note that the correct DSI interfaces and commands are used, DSI1 is recommended by default.

dtoverlay=vc4-kms-v3d
# DSI1 Use
dtoverlay=vc4-kms-dsi-waveshare-panel-v2,7_0_inch_a
# DSI0 Use
# dtoverlay=vc4-kms-dsi-waveshare-panel-v2,7_0_inch_a,dsi0

• 3. Insert the TF card into the Raspberry Pi, the device will automatically recognize the display and touch screen after powering on, and you can use it normally.

Method 2: Flash Pre-installed Image

1. Download and unzip the Raspberry Pi pre-installed image as an .img file
7-DSI-TOUCH-A pre-installed image
2. Connect the TF card to the PC, format the TF card with SDFormatter software.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click Write to flash the system image.
4. After the image flashing is completed, connect the TF card to the Raspberry Pi, start the Raspberry Pi, and wait for about 30 seconds for it to be displayed and touched normally.

Bookworm Display Rotation

GUI interface rotation

• 1. Open the "Screen Configuration" application;
  

• 2. Go to "Screen" - > "DSI-1" - > "Touchscreen" and check "6-0038 generic ft5x06(79)"
  

• 3. Click "Apply" and close the current window. Restart according to the pop-up prompt, and then touch screen select Done.

• 4. Go to "Screen" -> "DSI-1" -> "Orientation", check the direction you need to rotate, and finally click "Apply" to complete the screen and touch synchronous rotation.

lite version display rotation

• 1. Need to modify the /boot/firmware/cmdline.txt file:

sudo nano /boot/firmware/cmdline.txt

• 2. At the beginning of the cmdline.txt file, add the command for displaying the rotation angle: (Please note, this command needs to be on the same line, with each command separated by a space.)

video=DSI-1:720x1280M@60,rotate=90

Change the display rotation angle by modifying the rotate value to 90, 180, or 270.

• 3. Save and restart

sudo reboot

Install Reference Instructions

1. Ensure the opening size of the cabinet according to the size of the HMI.

2. Drill holes in the cabinet according to the hole size in step 1.

3. Embed the HMI in the cabinet from the outside.

4. Align the screw holes (no threaded holes) of the matching snap with the snap mounting holes on the HMI.
5. Tighten with 4 M2.5*8 screws through the buckle to fix the buckle to the HMI; Then use 4 M3 screws to pass through the screw hole (threaded hole) of the buckle, and tighten it clockwise through the buckle to the end.

Remote Login Raspberry Pi

Configure Wi-Fi

• On Raspberry Pi devices that support the 5GHz band (e.g. Pi 3B+, Pi 4, CM4, Pi 400), you need to set the country code before you can use the Wi-Fi network normally.

1. Open the terminal, input sudo raspi-config, select Localisation Options > WLAN Country (set the country code), press Enter.
2. Choose your country from the list (e.g., China would be CN), confirm by clicking OK. (If you don't know your country code, you can find it at wikipedia)
3. Go back to the main interface, press Finish, the system will prompt to restart, select Yes, and wait for the Raspberry Pi to restart.
4. After completion, you'll be able to connect to the Wi-Fi network on your Raspberry Pi and enter the password to complete the connection.

Find Device IP

Obtaining the IP address of the Raspberry Pi is a prerequisite for remote login, please refer to the following steps after configuring the WIFI or connecting the network cable.

View IP Address on Desktop

If you use a desktop operating system, hovering the mouse over the network icon in the upper right corner will display the name of the current network and the IP address.

 ipconfig  

nmap -sn 192.168.0.0/24

sudo apt update
sudo apt full-upgrade

sudo apt install rpi-connect
