Note: most users will not need to build the firmware as it can be fully configured through a web-based configuration tool!

GCC for ARM - https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads
-
GNU Make - https://www.gnu.org/software/make/ Windows executable is available at http://gnuwin32.sourceforge.net/packages/make.htm

Windows users: rm.exe from coreutils.
Running make in a console window in this directory builds the firmware. The resulting firmware.bin and firmware.hex are located in the build directory.
Running make program flashes the firmware, assuming you are using the LCP81x-ISP tool.
Files in the firmware root directory are source code that is processor hardware independent. The hal/ folder contains processor-specific light controller functionality such as MCU initialization, GPIO, SPI, UART etc. LPC8xx/ contains header files provided by NXP for the LPC812 MCU. light_programs/ contains example light programs you can use for reference. Output files of the build process are placed in the build/ folder.
