I tried taking the dip_arithmetic make file and changing it to load my bottle jam file. Have not been able to do it so far. Not sure why. I am running windows 7. I have got the Nerd Kits dip_arithmetic program to load and work as well as the others. There is something I am not seeing.Thanks for any help.

The error I get is

make-c ''/libnerdkits make: ''/libnerdkits: no such file or directory make: [bottle_jam.hex] error 2

My modified make file:

GCCFLAGS=-g -Os -Wall -mmcu=atmega168 LINKFLAGS=-Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm AVRDUDEFLAGS=-c avr109 -p m168 -b 115200 -P com3 LINKOBJECTS=../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o

all: bottle_jam-upload

bottle_jam.hex: bottle_jam.c make -C ../libnerdkits avr-gcc ${GCCFLAGS} ${LINKFLAGS} -o bottle_jam.o bottle_jam.c ${LINKOBJECTS} avr-objcopy -j .text -O ihex bottle_jam.o bottle_jam.hex

bottle_jam.ass: bottle_jam.hex avr-objdump -S -d bottle_jam.o > bottle_jam.ass

bottle_jam-upload: bottle_jam.hex avrdude ${AVRDUDEFLAGS} -U flash:w:bottle_jam.hex:a

The beginnings of my program, it will eventally count 2 rows of 3 bottles or 3 rows of 4 bottles then activate a machine proccess or set a alarm it's not finished. I know there is probably bugs in this part. I have not been able to load it to play with it yet. I usually would program this with a plc. A micro processor would be cheaper.So far I have been having a lot of fun with this I love learning new things.

Just put the code in indented form so it is a little easier to see what is going on.

David -

Is there a file called "Makefile" inside your libnerdkits directory? And is that directory at the same level (i.e. common parent directory) as your bottle_jam directory? If so, could you please post the contents of that file as well?

David, along what pcbolt was saying...

The standard NerdKit makefile assumes a certain directory (folder) structure. The reason for this is that it keeps thier libraries in a common directory for all their projects. Those libraries are the LCD, UART, and DELAY libraries. In the standard setup, there is also a shared makefile in the libnerdkits directory that creates the object files for those libraries. If your program uses any of those, you will need to keep your project directory in the NerdKit CODE directory so the structure would look something like this:

Code─┐
     │
     ├── bootloader168
     ├── bootloader328P
     ├── dip_arithmetic
     ├── dip_arithmetic_edu
     ├── initialload
     ├── led_blink
     ├── libnerdkits
     ├── tempsensor
     ├── tempsensor_edu
     ├── trafficlight
     └── YOUR PROJCET DIRECTORY

Using this structure would allow your makefile to find the library files and your error should go away.

It can be done other ways but that requires a bit more work in the makefile.
