Attiny source code

Installation Microchip toolchain

https://www.microchip.com/en-us/tools-resources/develop/microchip-studio/gcc-compilers

linux: add path of extracted archive to your PATH (e.g. in .bashrc: export PATH="$PATH:/<path>/avr8-gnu-toolchain-linux_x86_64/bin")

add /home/<user>/avr8-gnu-toolchain-linux_x86_64/avr/include to C_INCLUDE_PATH

install package avr-libc (``` /usr/lib/gcc/avr/5.4.0/../../../avr/bin/ld: cannot find crtattiny461a.o: No such file or directory collect2: error: ld returned 1 exit status make: *** [Makefile:48: bin/robox.elf] Error 1


### Build source

```bash
$ make help
