SDR MK1 Software Defined Radio Firmware

This is the repository for the SDR MK1 Software Defined Radio firmware. The MK1 is based on the Atmel AT90USB1287 microcontroller and LM97593 DRC chipset from National Semiconductor. The firmware is using the excellent LUFA library from Dean Camera for communicating through USB.

Please note, that in order to be able to upgrade the firmware, you will need:

• Atmel FLIP utility together with the included USB driver.

Please refer the Firmware Upgrade Instructions Wiki page for how to perform the upgrade.

In order to work on source code, you will need:

• AVR studio 4, AVR Studio 5 or later
• LUFA library

Note, that although LUFA is relying on WinAVR for the GNU Tools (C compiler and such), the makefile for the SDR MK1 is able to use the toolchain provided with AVR Studio 5. If you are using the AVR Studio 4, you either have to download a separate AVR Toolchain Installer or install WinAVR. (I really haven't tested it with AVR Studio 4 + AVR Toolchain combo, so WinAVR approach is recommended for AVR Studio 4.)
