Perfect, i solved. Thank you very much. I mistakenly used powershell.

this is the link where you can download the "nologo" firmware and the .bin format logo. If anyone could give me a hand ...

http://www.filedropper.com/splashscreen

I tried typing these commands one at a time:

1. copy /b PanelDue-v3-5.0-nologo.bin+Splashfabbrica3d.bin Panelduefirmware.bin;
2. copy /b "PanelDue-v3-5.0-nologo.bin+Splashfabbrica3d.bin" Panelduefirmware.bin

but without results.

Unfortunately I had already tried, but I always get the same error message.

Hi, I am writing to you because I would like to modify the paneldue splashscreen but I have a problem in the last passage read in the instructions. (https://github.com/dc42/PanelDueFirmware).

I downloaded the correct firmware from here: "https://github.com/dc42/PanelDueFirmware/releases".
I have the v3.0a version of the paneldue (5 ")

I created the "Splashfabbrica3d.bin" file using the command: "bmp2c-escher3d.exe Splashfabbrica3d.bmp Splashfabbrica3d.bin -b -c"
When on powershell I type: "copy / b PanelDue-v3-5.0-nologo.bin + Splashfabbrica3d .bin Panelduefirmware.bin "I get an error message:

**"Copy-Item : Impossibile trovare un parametro posizionale che accetta l'argomento 'Panelduefirmware.bin'.
In riga:1 car:1

• copy /b PanelDue-v3-5.0-nologo.bin+Splashfabbrica3d.bin Panelduefirmw ..."**

All the files are in the \user folder\Carlo.
So I can't create the file to install on the paneldue.
Can you give me some advice?

Thanks in advance. Good evening.
