##The `gcc` Required Math Library Packages
The following packages are required to be complied and installed in order to compile `gcc`. They are not available through the `cygwin` package system, so we have to make them ourselves. They must be complied in this order because each one depends on the previous.

##Buliding `binutils`, `gcc`, and `avr-libc` for the AVR system

For building the `avr-libc`, we have to specify the host build system. In my case it is `x86_64-unknown-cygwin`. You can look for build system type in the `gcc` configure notes for the proper `--build` specification to pass when you configure `avr-libc`.

###Installing Precompiled `dfu-programmer` Binaries (Not recommended)
To install the `dfu-programmer` from the binaries, we must get if from [the `dfu-programmer` website](https://dfu-programmer.github.io/) ([0.7.2](http://iweb.dl.sourceforge.net/project/dfu-programmer/dfu-programmer/0.7.2/dfu-programmer-win-0.7.2.zip)).
Copy this file into your `cygwin` home\src directory. (For me, it is `C:\cygwin64\home\Kevin\src`), extract the files, move `dfu-programmer.exe` to `~/local/avr/bin`. Most obnoxiously, the `libusb0_x86.dll` and `libusb0.sys` need to be moved from `./dfu-prog-usb-1.2.2/x86/` to a directory in the `Windows` `PATH` and the `cygwin` `PATH`. I achieved this by moving the files with Windows Explorer (you know, click and drag...) to `C:\cygwin64\home\Kevin\local\avr\bin` Then, in a `WINDOWS` command prompt running:

- Try making sure your `PATH` variables are set correctly for both `Windows` and `cygwin`.
- Make sure the `dll` is named correctly.
- Do not extract it with `cygwin`'s `unzip` as it does not set the executable permission. If you did it anyway, do `chmod +x dfu-programmer.exe`.
- Still have problems? Try building it instead.
##Debugging Tools
These tools are for debugging your firmware, etc. before flashing. Theoretically, it can save your flash memory from wearing out. However, these tool do not work 100% for the Planck firmware.

### `gdb` for AVR
`gdb` has a simulator for AVR but it does not support all instructions (like WDT), so it immediately crashes when running the Planck firmware (because `lufa.c` disables the WDT in the first few lines of execution). But it can still be useful in debugging example code and test cases, if you know how to use it.

### `simulavr`
`simulavr` is an AVR simulator. It runs the complied AVR elf's. `simulavr` does not support the `atmega32u4` device... it does `atmega32` but that is not good enough for the firmware (no PORTE and other things), so you cannot run the Planck firmware. I use it to simulate ideas I have for features in separate test projects.

This one is a major pain in the butt because it has a lot of dependencies and it is almost always buggy. I will do my best to explain it but... it was hard to figure out. A few things need to be changed in the 'Makefile' to make it work in `cygwin`.
