| ##### This Makefile will make compiling Atmel AVR | ||
| ##### micro controller projects simple with Linux | ||
| ##### or other Unix workstations and the AVR-GCC | ||
| ##### tools. | ||
| ##### | ||
| ##### It supports C, C++ and Assembly source files. | ||
| ##### | ||
| ##### Customize the values as indicated below and : | ||
| ##### make | ||
| ##### make disasm | ||
| ##### make stats | ||
| ##### make hex | ||
| ##### make writeflash | ||
| ##### make gdbinit | ||
| ##### or make clean | ||

| #################################################### | ||
| ##### ##### | ||
| ##### Configuration ##### | ||
| ##### ##### | ||
| ##### Customize the values in this section for ##### | ||
| ##### your project. MCU, PROJECTNAME and ##### | ||
| ##### PRJSRC must be setup for all projects, ##### | ||
| ##### the remaining variables are only ##### | ||
| ##### relevant to those needing additional ##### | ||
| ##### include dirs or libraries and those ##### | ||
| ##### who wish to use the avrdude programmer ##### | ||
| ##### ##### | ||
| ##### See http://electrons.psychogenic.com/ ##### | ||
| ##### for further details. ##### | ||

| ##### Target Specific Details ##### | ||
| ##### Customize these for your project ##### | ||
|
|
||
| # Name of target controller | ||
| # (e.g. 'at90s8515', see the available avr-gcc mmcu | ||
| # options for possible values) | ||
| MCU=atmega88p | ||
|
|
||
| # id to use with programmer | ||
| # default: PROGRAMMER_MCU=$(MCU) | ||
| # In case the programer used, e.g avrdude, doesn't | ||
| # accept the same MCU name as avr-gcc (for example | ||
| # for ATmega8s, avr-gcc expects 'atmega8' and | ||
| # avrdude requires 'm8') | ||
| PROGRAMMER_MCU=m88 | ||
|
|
||
| # Name of our project | ||
| # (use a single word, e.g. 'myproject') | ||
| PROJECTNAME=ngc | ||
|
|
||
| F_CPU=20000000 | ||
|
|
||
| # Source files | ||
| # List C/C++/Assembly source files: | ||
| # (list all files to compile, e.g. 'a.c b.cpp as.S'): | ||
| # Use .cc, .cpp or .C suffix for C++ files, use .S | ||
| # (NOT .s !!!) for assembly source code files. | ||
| PRJSRC=uart.c main_power_calc.c | ||
|
|
||
| # additional includes (e.g. -I/path/to/mydir) | ||
| INC= | ||
|
|
||
| # libraries to link in (e.g. -lmylib) | ||
| LIBS= | ||
|
|
||
| # Optimization level, | ||
| # use s (size opt), 1, 2, 3 or 0 (off) | ||
| OPTLEVEL=1 | ||

||
| ##### AVR Dude 'writeflash' options ##### | ||
| ##### If you are using the avrdude program | ||
| ##### (http://www.bsdhome.com/avrdude/) to write | ||
| ##### to the MCU, you can set the following config | ||
| ##### options and use 'make writeflash' to program | ||
| ##### the device. | ||
|
|
||
|
|
||
| # programmer id--check the avrdude for complete list | ||
| # of available opts. These should include stk500, | ||
| # avr910, avrisp, bsd, pony and more. Set this to | ||
| # one of the valid "-c PROGRAMMER-ID" values | ||
| # described in the avrdude info page. | ||
| # | ||
| AVRDUDE_PROGRAMMERID=avrispv2 | ||
|
|
||
| # port--serial or parallel port to which your | ||
| # hardware programmer is attached | ||
| # | ||
| AVRDUDE_PORT=/dev/ttyUSB2 | ||
