Hello everybody,

I am currently stuck with the following problem

 ![Screenshot 2023-04-11 225425](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/2/e/2eb0c829a0fb88dd88c6cda1440dc5fb492c5296.png)

Error: ENOENT: no such file or directory, open '/dev/i2c-1'

have already tried to fix the error with the following link  
[https://forums.raspberrypi.com/viewtopic.php?t=115080](https://forums.raspberrypi.com/viewtopic.php?t=115080)

here is my config.txt

```auto

  GNU nano 5.4 /boot/config.txt
# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
dtparam=i2c_arm=on
dtparam=i2c1=on
dtparam=spi=on
dtparam=i2s=on
#dtparam=i2s=on

# Uncomment this to enable infrared communication.

dtoverlay=hifiberry-dac
dtoverlay=hifiberry-dacplus

```

maybe someone has a few tips for me, would be very pleased

cheers

Did you enabled the i2c with **sudo raspi-config** and then interface?
