Hi,

I copied the source files from the project website to a directory named keyboard including the font.txt keymap.h and keymapper.py files. I copied the Makefile from bit_arithmetic and changed all the instances of "dip_arithmetic" to "keyboard". When I run make I get "No rule to make target keyboard.hex, needed by keyboard-upload".

Here is the Makefile I'm using.

Thanks, Bob

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 /dev/ttyUSB0
LINKOBJECTS=../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o

all:    keyboard-upload

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

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

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

Hi bobc,

It looks like there is a tempsensor.hex target in there for some reason. That should have been dip_arithmetic.hex, which would have been changed to keyboard.hex in your replace all. Change that to tempsensor.hex to keyboard.hex and it should work.

Thanks, that was it! I don't know how many times I looked at that Makefile and did not see that. Ugh.

I've encountered this problem, but not since I started doing this in my makefiles:

PROJ=keyboard

all:    ${PROJ}-upload

${PROJ}.hex: ${PROJ}.c

etc.

bretm, Great idea! Thanks Bob

I copied the source files from the project website to a directory named keyboard including the font.txt keymap.h and keymapper.py files. I created a makefile but all I get is ? and I type a letter I get ?? also can please someone explain the python code ? thank you

Ooops Data and clock were swapped. Ignore last post

Sorry to hijack the thread but I am having the same sort of error response when trying to make my latest project. I would think the error lies somewhere within the makefile aswell, but cannot find where I went wrong. Sorry to bother you all with something so trivial, but this really is bugging me.Thanks

Makefile (template from the initialload makefile)

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 /dev/ttyUSB0
ProjectName = {testmotor}
LINKOBJECTS=../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o

all:    ${ProjectName}-upload

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

${ProjectName}.ass:    ${ProjectName}.hex
avr-objdump -S -d ${ProjectName}.o > ${ProjectName}.ass

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

comes back with this error code: No rule to make target '{testmotor}.c' needed by '{testmotor}.hex

Only put the braces where you are substituting the variable value, not where you assign it. Try this:

ProjectName = testmotor
