 # Building from source
 Precompiled binaries of the firmware are [available](http://microfluidics.utoronto.ca/gitlab/dstat/dstat-firmware/builds) from the automated build system (click the download button for the desired build) and can be uploaded using [avrdude](http://www.nongnu.org/avrdude/) or Atmel Studio.

 This will produce the firmware binaries that will be loaded onto the microcontroller.
 `atxmega256a3u_104.hex` is a bootloader for upgrading firmware over USB after the initial flash (currently experimental) and `dstat-firmware.hex` or `dstat-firmware.elf` is the actual firmware.

 ## Building with Make (using Docker)
 
 On Windows, the easiest way to compile the source is using make from docker (Keep in mind you can use the automated build system if you don't intend to make modifications to the firmware).:
 
 1. Install docker from https://docs.docker.com/docker-for-windows/
 2. Use the tray icon for Docker to enable sharing on your C drive (under Shared Drives)

    Replacing `c:/Users/mdryden/src/dstat-firmware/DSTAT` with the path to wherever you cloned the source.
    This should compile your source files and you can upload them with avrdude or Atmel Studio.
