Running the C Example

• Download the example (skip if already downloaded)

  wget https://files.waveshare.com/wiki/1.54inch_e-Paper_E/1.54inch_e-Paper_E.zip
  unzip 1.54inch_e-Paper_E.zip -d 1.54inch_e-Paper_E
  cd 1.54inch_e-Paper_E/RaspberryPi_JetsonNano/

  Alternative extraction method

  sudo apt-get install p7zip-full
  7z x 1.54inch_e-Paper_E.zip -O./1.54inch_e-Paper_E
  cd 1.54inch_e-Paper_E/RaspberryPi_JetsonNano/

  Download the program via GitHub (alternative method, skip if already downloaded)

  • Accessing GitHub may not be very smooth at present. It is recommended to use the above method to download from our official website.

    git clone https://github.com/waveshare/e-Paper.git
    cd e-Paper/E-paper_Separate_Program/1.54inch_e-Paper_E/RaspberryPi_JetsonNano

• Compile the program (Note: -j4 uses 4 threads for compilation; you can modify the number)

  # It is now in 1.54inch_e-Paper_E/RaspberryPi_JetsonNano
  cd c
  sudo make clean
  sudo make JETSON -j4

• Run the program

  sudo ./epd

Running the Python Example

• Install libraries

  sudo apt-get update
  sudo apt-get install python3-numpy
  sudo apt-get install python3-pip
  sudo pip3 install Jetson.GPIO
