Hi @nerd ,
I finally got some time to test it out and commenting out dtparam worked ! Thanks a lot !
And for the #, I was indeed missing the \ in the formatting

Hey @l_italien_adg,
The /boot/volumioconfig.txt is replaced with every upgrade. Please add to your Volumio upgrade or OTA additional step to comment out dtparam=i2c_arm=on
line.
Kind Regards,
Hi @gvolt! Mind me if can help me with this, i manage to work with 7 inch display maybe it because of luck. I bought this screen from someone in online market and he says he bought it in here "
7inch HDMI Display-C - LCD wiki".
However, i found out some error with this screen, and I’d try to look this model and brand and i found this exactly same with this touch screen from here "
Raspberry Pi 7 -inch HDMI Interface 1024x600 Capacitive Touch Screen : Amazon.in: Computers & Accessories".
Unfortunately, this product is currently not available and the information is limited also.
I am using rpi3b+
Latest os
Hifiberry dac hat
7 inch touch display.
And here are my current lines in userconfig.
max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=7
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_drive=1
display_rotate=0
hdmi_cvt 1024 600 60 6 0 0 0
disable_overscan=1
hdmi_blanking=1
display_auto_detect=1
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch
It is working but, as per gelo5 maybe something wrong with the touch configuration because the peppy is not well fitted with the screen.
Thanks,
In case you have a problem related to peppy I can’t help, sorry. Please also note the advice from @Wheaten in the peppy specific thread.
P.S. If you specify the version of a software, please do not write “latest”, but enter the specific version number. Only then a reader can know which version is actually meant.
hdmi_mode=1
and hdmi_mode=87
in Raspberry Pi ConfigurationIn Raspberry Pi’s userconfig.txt
file, the hdmi_mode
setting is used to define the resolution and refresh rate of the HDMI output. However, the way hdmi_mode
behaves depends on another setting: hdmi_group
.
hdmi_mode=1
(Not Recommended Without hdmi_group
Set)hdmi_mode=1
is ambiguous because it depends on hdmi_group
.hdmi_group=1
(CEA mode): hdmi_mode=1
sets VGA resolution (640x480 @ 60Hz).hdmi_group=2
(DMT mode): hdmi_mode=1
sets an unknown low-resolution mode (not typically used).hdmi_mode=87
(Custom Resolution)hdmi_mode=87
is a special mode that tells the Raspberry Pi to use a custom resolution, defined by hdmi_cvt
or hdmi_timings
parameters.hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 60 6 0 0 0
This sets a 1024x600 resolution at 60Hz, which is common for small LCD screens.hdmi_mode=1
and hdmi_mode=87
Not Be Mixed?hdmi_mode=1
depends on hdmi_group
, whereas hdmi_mode=87
requires a custom resolution.
hdmi_mode=1
while also trying to use hdmi_mode=87
, it may lead to unpredictable behavior.hdmi_mode=1
expects predefined resolutions, while hdmi_mode=87
overrides these settings with a custom one.Conflicting Resolution Settings
hdmi_mode=87
requires hdmi_group=2
(DMT mode), whereas hdmi_mode=1
defaults to CEA
(unless explicitly set otherwise).Potential Boot Issues
hdmi_group=2 # DMT mode
hdmi_mode=82 # 1920x1080 @ 60Hz (for example)
hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 60 6 0 0 0 # Custom resolution settings
I wonder where your understanding that both panels are the same have come from. They are sharing similar physical parameters, however both are distinctly different. Upon reviewing the information, here’s a comparison between the KD07002 and MPI7002 display modules:
Feature | KD07002 | MPI7002 |
---|---|---|
Type | 7-inch HDMI Display with Capacitive Touch | 7-inch HDMI Display with Capacitive Touch |
Resolution | 1024×600 pixels | 1024×600 pixels |
Touch Support | 5-point capacitive touch | 5-point capacitive touch |
Reatlek chip | RTD2660H-K6M26G2 | RTD2660H-R8040CI |
Dimensions | Not specified | 164.9 × 124.27 mm |
Power Consumption | 5.5V via USB for touch interface | 0.84A at 5V |
Compatibility | Raspberry Pi and other devices | Raspberry Pi, BB Black, Banana Pi, and other mainstream mini PCs |
Additional Features | HDMI input for display; USB interface for touch control; supports backlight control, 3.5mm Audio jack CEC | HDMI input for display; USB interface for touch control; supports backlight control |
The RTD2660H is a flat panel display controller commonly used in various display modules. The suffixes “R8040CI” and “K6M26G2” refer to specific firmware versions or configurations tailored for different display modules. These suffixes indicate variations in features such as input interfaces, supported resolutions, or other functionalities. Unfortunately, detailed public information about these specific configurations is limited. For precise differences between the RTD2660H-R8040CI and RTD2660H-K6M26G2 versions, it would be best to consult the manufacturer’s documentation or contact their technical support directly.
Please note that while both models share similar specifications, the exact dimensions and power consumption details for the KD07002 are not specified in the available sources.
Kind Regards,
It is unclear to me what the problem is. According to
the display seems to work.
Hi @gvolt! My concerns is something went wrong with my peppyscreensaver cause when i use the custom skins from gelo5 1024x600 and load it to my screen. The peppy skin are not fitted or cover the whole screen just like picture below.
Thank you nerd for giving me some information with my touch display, for now I’m good with my setup.
This is a problem that appears to be unrelated to the Touch Display plugin. I recommend looking for help in the dedicated Peppy thread.
I already ask help for gelo5 for this thank you gvolt and nerd for helping me
I imagine that your post there did not describe your problem clearly enough - you only wrote in a general way that you have difficulties with peppymeter.
Hi,
I’m trying volumio since two weeks. I can access via my Mac easily, playing music, but I just can’t get the touch display to work.
I am using rpi3b+
Volumio os 3.785
Hifiberry dac hat
7 inch original Raspi touch display (bought in 2018).
Touch Display Plugin 3.5.1
The display works fine with actual Raspberry OS, but I prefer volumio to build a music streamer at home.
I tried some configuration here in this forum.
I’ve access to the raspi via ssh.
I made following changes via ssh to the userconfig.txt
hdmi_group=2
hdmi_mode=87
hdmi_ignore_edid=0xa5000080
hdmi_timings=1280 0 64 2 18 400 0 10 3 42 0 0 0 60 0 37330000 3
hdmi_drive=1
But the display remains dark.
Have you some idea how to make it work?
Thanks for you help
Replace your settings in “/boot/userconfig.txt” with
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch
Thanks, gvolt, for the quick reply.
First I opened file with
nano userconfig.txt
Than reboot
display is still dark
Than I thought to be careful with path and opened with
nano /boot/userconfig.txt
who were empty.
But now I can’t write the file. I’ve the message:
Cannot open file for writing: No such file or directory
I agree that I don’t know raspis world very well.
Please post the output of
ls -al /boot/*config.txt
zsh: no matches found: /boot/*config.txt
Are you at all connected to your Pi via SSH?
I think so. I’ve opened with Terminal on the mac with
volumio@IP-Adress in my network
Before I started in /dev the ssh
Than I had these lines:
