Northwestern Wireless IoT Base

Base files for Northwestern course CS397/497: Wireless Protocols for IoT. This repository has applications and board initialization that connects to the build system provided by nrf52x-base.

Requirements

  1. Various tools

    • build-essential (make)
    • python3
    • git

  2. ARM cross-compiler toolchain: gcc-arm-none-eabi toolchain

    On Ubuntu:

    cd /tmp \
&& wget -c https://developer.arm.com/-/media/Files/downloads/gnu-rm/9-2020q2/gcc-arm-none-eabi-9-2020-q2-update-x86_64-linux.tar.bz2 \
&& tar xjf gcc-arm-none-eabi-9-2020-q2-update-x86_64-linux.tar.bz2 \
&& sudo mv gcc-arm-none-eabi-9-2020-q2-update /opt/gcc-arm-none-eabi-9-2020-q2-update \
&& rm gcc-arm-none-eabi-9-2020-q2-update-x86_64-linux.tar.bz2 \
&& sudo ln -s /opt/gcc-arm-none-eabi-9-2020-q2-update/bin/* /usr/local/bin/.

    On MacOS:

    brew tap ArmMbed/homebrew-formulae
brew install arm-none-eabi-gcc

  3. JTAG programming tools: Segger JLink

    Pick the correct package for your OS under "Software and documentation pack".

Installation

  • Clone the repository
  • Change directory into the repository
  • git submodule update --init --recursive (this will take a couple minutes to complete)

Building and loading applications

To build an application, use make inside of the application's directory.

Two other targets will be particularly helpful:

  • make flash uploads the application to the board using JTAG
  • make rtt opens a debug window with print output from the board
