Hi guys, im porting froma nd arduino nano, to a stand alone board.

Y got some atmega48 TQFP that i get as a gift, and i want to know if there is a way to make it work whit arduino ide.

I try to upload the hex file (blink led) for the mega328 to the mega48 but the led didint blink.

Can anyone help me on this?

Well ill awnser myself.

To get working an atmega48 whit arduino ide, just add this board to Boards.txt in the arduino directory.

Code: [Select]
atmega48.name=Rotceh-hack QM7298 w/ ATmega48V xD

attiny48.upload.using=arduino
atmega48.upload.maximum_size=4094
atmega48.upload.speed=19200

atmega48.bootloader.low_fuses=0xE2
atmega48.bootloader.high_fuses=0xDF
atmega48.bootloader.extended_fuses=0xFF
atmega48.bootloader.path=atmega
atmega48.bootloader.file=atmega48.hex
atmega48.bootloader.unlock_bits=0x3F
atmega48.bootloader.lock_bits=0x0F

atmega48.build.mcu=atmega48
atmega48.build.f_cpu=8000000L
atmega48.build.core=arduino
atmega48.build.variant=standard

Then just compile ur scketch and upload it whit avrdude in command promp.

Or if u want upload it whit the arduino interfaz ull need to modifie the avrdude.conf file ( arduino-1.0.1\hardware\tools\avr\etc) and change the signature of the atmega48.

I tried the same thing but it did not work. When I try to compile the bare minimum or blink sketch I get this error:

\arduino\arduino-1.0.5\hardware\arduino\cores\arduino/Arduino.h:213:26: error: pins_arduino.h: No such file or directory

any ideas?
