Flipper

About

Flipper is a new kind of embedded development platform that lets developers use familiar tools to create amazing applications that interact with embedded hardware. Flipper can be controlled from these programming langauges running on desktop, mobile, and web applications.

1. Purchase a board from our web store here.
   • You can't get started without a board. Pick one up today!
2. Visit this Wiki page to set up your environment.
   • Our Wiki is easy to navigate. Start at the top and work your way through it.
3. Try out the examples here.
   • The best way to learn is by example. Dive head first into our intuitive examples.
4. Ask questions!
   • We are building a community around the platform, and we want you to be a part of it. Join our Discord server and ask questions, email us, or open issues here on GitHub.

Quickstart

Install the dependencies

To build Flipper, you first need to install the project dependencies. To build firmware images for the device you will need to install two GNU cross compilers: avr-gcc and arm-none-eabi-gcc. To build and use libflipper you will need to install libusb-1.0. To build and install the console you will need to install the rust compiler and tools. To write firmware images to the device, you will need dfu-programmer. You may selectively install dependencies depending on what you wish to contribute to.

Homebrew

brew tap osx-cross/avr osx-cross/arm
brew install rust libusb avr-gcc dfu-programmer arm-gcc-bin

APT (Ubuntu 18.04)

apt-get install build-essential libusb-1.0-0-dev
apt-get install dfu-programmer avr-libc binutils-avr gcc-avr
apt-get install libnewlib-arm-none-eabi binutils-arm-none-eabi gcc-arm-none-eabi
apt-get install pkg-config python3-pip python3-pyelftools

dnf (Fedora 28)

dnf install libusb-devel-1
dnf install dfu-programmer avr-{gcc,gdb,binutils,libc}
dnf install arm-none-eabi-{gcc,gdb,binutils,newlib}
dnf install pkg-config "python?-pip" "python?-pyelftools"

Rust

In addition to the dependencies installed via apt or brew, you will need to install the Rust toolchain in order to compile the console. Cross-platform instructions on installing Rust can be found at rustup.rs.

Clone and build the repository

git clone https://github.com/flipper-io/flipper.git
cd flipper
make

To selectively build components of the project, see the table below.

Target	Description
make libflipper	Builds the library that talks to the hardware.
make console	Builds the console tool that creates and manages projects.
make atmegau2	Builds the firmware for the microcontroller.
make atsam4s	Build the embedded operating system for the microprocessor.
make utils	Builds the utilities needed to flash and debug the hardware.

All of the intermediates are placed in the build directory.

Install the tools

Once you've built, you can install the platform library and tools.

make install

The default PREFIX for installation is /usr/local/. If you wish to change the prefix, set the prefix before the install like PREFIX=/path/to/prefix make install

If you are on Linux, you will need to install the udev rule that lets libflipper talk to the hardware. You will then need to trigger a rule reload:

cp assets/99-flipper.rules /etc/udev/rules.d
udevadm trigger

Add the Libraries to your Linker Path

Once the libraries are installed, you may need to add /usr/local/lib/ to your linker search path. This can be done by running the following command as a user with sudo permissions.

echo /usr/local/lib | sudo tee -a /etc/ld.so.conf.d/local.conf
sudo ldconfig

Updating the Firmware

Once you get everything installed, you should update your board's firmware. Attach only one Flipper device to your computer via USB, and then run the following command.

make install-atmegau2
make install-atsam4s

Example

Once you've installed the platform library and tools, you can try the example.

cd examples/app
make

This will build an application for the device. You can then install this application onto the attached device.

make install

See the README for each example for details.
