Get a copy of the project, if you haven't already. When you're running Debian (or another Linux) this will do the job:
git clone git://github.com/breaker27/smarthomatic
Go into the subdirectory of the device you want to build (e.g. “firmware/shc_basestation/”) and build the firmware:
john@doe:~/shc$ cd smarthomatic/firmware/shc_basestation/ john@doe:~/shc/smarthomatic/firmware/shc_basestation$ make avr-gcc -c -gdwarf-2 -DF_CPU=20000000UL -DUART_BAUD_RATE=19200UL -DUART_RX=1UL -Os -mmcu=atmega328 -I. -fdata-sections -ffunction-sections -fpack-struct -fshort-enums -Wall -Wstrict-prototypes -Wundef -std=c99 -Wa,-adhlns=build/ [...] avr-objdump -h -S build/shc_basestation.elf > build/shc_basestation.lss avr-nm -n build/shc_basestation.elf > build/shc_basestation.sym Fuses: LFUSE = 0xF7 HFUSE = 0xD1 EFUSE = 0x07 Image size: text data bss dec hex filename 17264 33 739 18036 4674 build/shc_basestation.elf john@doe:~/shc/smarthomatic/firmware/shc_basestation$
The resulting files are stores in the bin subdirectory from where you started the make command.
