This includes:
* Cmake clean up - thanks @Qyriad
* Windows binaries saved after each appveyor build
* A bump to the Visual Studio version that we use to build it
* An appveyor cygwin script for building firmware, it doesn't work but it seems like someone might pick it up and make it work, or blow it away if we switch to Travis firmware artefacts
By default, CMake assumes that the project is using both C and C++. By
explicitly passing 'C' as argument of the project() macro, we tell CMake
that only C is used, which prevents CMake from erroring out if a C++
compiler doesn't exist.
Conflicts:
firmware/common/si5351c.c
Preferred Si5351C configuration that drives 40MHz into the LPC43xx GP_CLKIN.
Added HACKRF_ONE qualifier for CPLD TMS/TDI swap.
* Fixed wait() by using volatile else the loop was removed by GCC.
Tested it with SPIFI work fine:
SPIFI tested with LPCXpresso+NXP LPC Link (from LPCXpresso Board LPC1769 Debugger)
-> Program Flash with Flash Driver LPC1850A_4350A_SPIFI.cfx
-> Select file: firmware\blinky\blinky.bin
-> Base address 0x14000000 & option Erase only required pages
