Prerequisites#

• Raspberry Pi with RPi OS Lite (flash to SD card)
• E-Paper display module
• Linux development machine with Qt installed

Setup#

On Linux (Development Machine)#

Find your host IP address:

hostname -I

Search for Raspberry Pi IP address:

nmap -sn <host_address>/24

Generate an SSH key pair:

ssh-keygen -t ed25519 -C "qt-deployer" -f ~/.ssh/id_ed25519

Copy the public key to the Raspberry Pi:

ssh-copy-id -i ~/.ssh/id_ed25519.pub <username>@<remote_address>

Clone the repository:

git clone https://github.com/AhmadRoshanfar/EPaper-Photo.git
  cd RPi-EPaper

Transfer project files to Raspberry Pi:

scp -r ./RPi-EPaper pi@192.168.8.39:~

On Raspberry Pi (Target Device)#

Enable SPI interface:

sudo raspi-config nonint do_spi 0

Usage#

• Run the Qt application on your development machine
• Choose your image
• Enter username and host address
• Press Sync and wait until the image uploads to the display
