FPGA - Raspberry Pi Communication Demo

Sample code for communicating between a raspberry pi and de0 nano at high speed over the GPIO pins by sending the accelerometer data.

Serial Example

  • Plug GPIO03 on the de0-nano into GPIO 15 on the Raspberry Pi.
  • Plug GPIO05 on the de0-nano into GPIO 14 on the Raspberry Pi.

To load the de0nano, can either import the verilog and tcl files into your own quartus project, or use this pyquartus tool. To compile and upload using pyquartus, plug your de0-nano into your computer, and run:

cd de0-nano-raspi-serial-demo
pyquartus -c -u -i de0nano/common -p de0nano/serial

On the raspberry pi side, install the requirements and run the program:

cd de0-nano-raspi-serial-demo/raspi
pip install -r requirements.txt
python serial/main.py

The serial verilog code was adapted from [Jean P Nicolle at fpga4fun] (http://fpga4fun.com/).

Parallel Example

  • Plug GPIO 133 on the de0-nano into GPIO 8 on the Raspberry Pi
  • Plug GPIO 131 on the de0-nano into GPIO 10 on the Raspberry Pi
  • Plug GPIO 129 on the de0-nano into GPIO 24 on the Raspberry Pi
  • Plug GPIO 127 on the de0-nano into GPIO 4 on the Raspberry Pi
  • Plug GPIO 125 on the de0-nano into GPIO 17 on the Raspberry Pi
  • Plug GPIO 132 on the de0-nano into GPIO 22 on the Raspberry Pi
  • Plug GPIO 130 on the de0-nano into GPIO 9 on the Raspberry Pi
  • Plug GPIO 128 on the de0-nano into GPIO 25 on the Raspberry Pi
  • Plug GPIO 126 on the de0-nano into GPIO 18 on the Raspberry Pi
  • Plug GPIO 124 on the de0-nano into GPIO 23 on the Raspberry Pi

To load the de0nano, can either import the verilog and tcl files into your own quartus project, or use this pyquartus tool. To compile and upload using pyquartus, your de0-nano into your computer, and run:

cd de0-nano-raspi-serial-demo
pyquartus -c -u -i de0nano/common -p de0nano/parallel

On the raspberry pi side, install the requirements and run the program:

cd de0-nano-raspi-serial-demo/raspi
pip install -r requirements.txt
python parallel/main.py
