Copy all the published application files and subdirectories to ~/TFTtag-Ili934x-for-OpenEpaperLink
Make application runnable using :
sudo chmod +x ~/TFTtag-Ili934x-for-OpenEpaperLink/TFTtag-Ili934x-for-OpenEpaperLink
Install the application as a service (Adjust TFTtag-Ili934x-for-OpenEpaperLink.service if user or directory is different) :
sudo systemctl stop TFTtag-Ili934x-for-OpenEpaperLink
sudo cp ~/TFTtag-Ili934x-for-OpenEpaperLink/TFTtag-Ili934x-for-OpenEpaperLink.service /etc/systemd/system/TFTtag-Ili934x-for-OpenEpaperLink.service
sudo systemctl daemon-reload
sudo systemctl enable TFTtag-Ili934x-for-OpenEpaperLink
sudo systemctl start TFTtag-Ili934x-for-OpenEpaperLink
Check if service is running ok :
sudo systemctl status TFTtag-Ili934x-for-OpenEpaperLink
or
sudo journalctl -u TFTtag-Ili934x-for-OpenEpaperLink
When using 'Publish' -> Visual Studio automatically synchronises all files to ~/TFTtag-Ili934x-for-OpenEpaperLink using WinSCP.
Adjust paths, ip address, user and password in .csproj file as required :
<Target Name="PiCopy" AfterTargets="Publish">
<Exec Command=""C:\Program Files (x86)\WinSCP\WinSCP.com" /command "open sftp://pi:raspberry@192.168.2.60/" "synchronize remote C:\dotnet\projects\TFTtag-Ili934x-for-OpenEpaperLink\TFTtag-Ili934x-for-OpenEpaperLink\bin\Release\net9.0\publish /home/pi/TFTtag-Ili934x-for-OpenEpaperLink/" "exit"" />
</Target>
Alternatively, you could also copy all the files using pscp, that comes with putty:
Target Name="PiCopy" AfterTargets="Publish">
<Exec Command="pscp -r -pw raspberry C:\dotnet\projects\TFTtag-Ili934x-for-OpenEpaperLink\TFTtag-Ili934x-for-OpenEpaperLink\bin\Release\net9.0\publish\ pi@192.168.2.60:/home/pi/TFTtag-Ili934x-for-OpenEpaperLink/" />
</Target>
First stop the application, before updating the files :
sudo systemctl stop TFTtag-Ili934x-for-OpenEpaperLink
