DWIN_T5UIC1_LCD
Python class for the Ender 3 V2 LCD runing klipper3d with Moonraker
https://github.com/arksine/moonraker
Setup:
Disable Linux serial console
By default, the primary UART is assigned to the Linux console. If you wish to use the primary UART for other purposes, you must reconfigure Raspberry Pi OS. This can be done by using raspi-config:
- Start raspi-config:
sudo raspi-config.
- Select option 3 - Interface Options.
- Select option P6 - Serial Port.
- At the prompt Would you like a login shell to be accessible over serial? answer 'No'
- At the prompt Would you like the serial port hardware to be enabled? answer 'Yes'
- Exit raspi-config and reboot the Pi for changes to take effect.
For full instructions on how to use Device Tree overlays see this page.
In brief, add a line to the /boot/config.txt
file to apply a Device Tree overlay.

Enabling Klipper's API socket
By default, the Klipper's API socket is not enabled. In order to use the API server, the file /etc/default/klipper need to be updated form
KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/printer.cfg -l /tmp/klippy.log"
To:
KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/printer.cfg -a /tmp/klippy_uds -l /tmp/klippy.log"

Wire the display
- Display <-> Raspberry Pi GPIO BCM
- Rx = GPIO14 (Tx)
- Tx = GPIO15 (Rx)
- Ent = GPIO13
- A = GPIO19
- B = GPIO26
- Vcc = 2 (5v)
- Gnd = 6 (GND)
Here's a diagram based on my color selection:

Enter the downloaded DWIN_T5UIC1_LCD folder. Make new file run.py and copy/paste in the following (pick one)
For an Ender3v2
#!/usr/bin/env python3
from dwinlcd import DWIN_LCD
encoder_Pins = (26, 19)
button_Pin = 13
LCD_COM_Port = '/dev/ttyAMA0'
API_Key = 'XXXXXX'
DWINLCD = DWIN_LCD(
LCD_COM_Port,
encoder_Pins,
button_Pin,
API_Key
)
If your control wheel is reversed (Voxelab Aquila) use this instead.
#!/usr/bin/env python3
from dwinlcd import DWIN_LCD
encoder_Pins = (19, 26)
button_Pin = 13
LCD_COM_Port = '/dev/ttyAMA0'
API_Key = 'XXXXXX'
DWINLCD = DWIN_LCD(
LCD_COM_Port,
encoder_Pins,
button_Pin,
API_Key
)
Run with python3 ./run.py
Run at boot:
Note: Delay of 30s after boot to allow webservices to settal.
path of `run.py` is expected to be `/home/pi/DWIN_T5UIC1_LCD/run.py`
sudo chmod +x run.py
sudo chmod +x simpleLCD.service
sudo mv simpleLCD.service /lib/systemd/system/simpleLCD.service
sudo chmod 644 /lib/systemd/system/simpleLCD.service
sudo systemctl daemon-reload
sudo systemctl enable simpleLCD.service
sudo reboot
