Arduino Builder 1.0.13
Arduino Builder is a standalone utility for viewing, compiling and uploading Arduino sketch files and compiled ELF or HEX files to Arduino boards with the Arduino serial programming interface, Arduino ISP or USBasp, without the need for the Arduino IDE. The app has a standard user interface with drop down menus to choose the data you need. The functions of the utility can be undertaken in 3 steps. When compiling is required, for uploading sketch file, Arduino Builder scans the sketch for referenced libraries and then builds the necessary libraries automatically. The distribution package contains Arduino 1.0.4 core and library files, AVR GCC compiler toolchain and AVRDUDE. Please be aware that as only the standard Arduino libraries are shipped with the utility, if you want to build with custom libraries, then you will need to place the library source code files with the identical directory name into /arduino/libraries directory.
