Working With Jetson Nano

Hardware Connection

The 40PIN pin of Jetson Nano is compatible with the 40PIN pin of Raspberry Pi and provides a Jetson.GPIO library with the same API as the RPI.GPIO library of Raspberry Pi, so the serial number connected here is the same as that of Raspberry Pi. The module can be directly inserted into the 40Pin headers of the Jetson Nano when using the 40PIN interface.
If you choose to connect with an 8PIN cable, please refer to the pin correspondence table below:

C

  • Download the demo via GitHub (you can skip this step if you have downloaded it.)
git clone https://github.com/waveshare/e-Paper.git
cd e-Paper/RaspberryPi_JetsonNano/
  • Download the test demo: (you can skip this step if you have downloaded it.)
sudo apt-get install p7zip-full
wget  https://files.waveshare.com/upload/3/39/E-Paper_code.7z
7z x E-Paper_code.7z -O./e-Paper
cd e-Paper/RaspberryPi_JetsonNano/
  • Compile the demo (Note: JETSON is the specified device, and RPI is not specified by default. -j4 is to compile by 4 threads, and the number can be changed by yourself. "EPD=epd2in9d" is to specify a macro definition, and "epd2in9d" corresponds to the test demo in the main function.)
# Now at e-Paper/RaspberryPi_JetsonNano
cd c
sudo make clean
sudo make JETSON -j4 EPD=epd2in9d
  • Run the demo.
sudo ./epd

Python

  • Install function library.
sudo apt-get update
sudo apt-get install python3-numpy
sudo apt-get install python3-pip
sudo pip3 install Jetson.GPIO
  • Download the demo via GitHub (you can skip this step if you have downloaded it.)
git clone https://github.com/waveshare/e-Paper.git
cd e-Paper/RaspberryPi_JetsonNano/
  • Download the demo (you can skip this step if you have downloaded it.)
sudo apt-get install p7zip-full
wget  https://files.waveshare.com/upload/3/39/E-Paper_code.7z
7z x E-Paper_code.7z -O./e-Paper
cd e-Paper/RaspberryPi_JetsonNano/
  • Run the demo.
# Make sure it's in e-Paper/RaspberryPi_JetsonNano/
cd python/examples/
