AVR Template Creator
This project aims to create a generic makefile useful for developing for AVR devices. While it is not perfect,
it does its job. I believe it's good for most AVR microprocessors. If you don't want to retype everything
every time, you can create a file with just the answers to the questions, such as in - then project creation
will be as simple as ./avr_template < in!
Sample run:
[adam@adam-Y510P /tmp]λ ~/avr/generic/avr_template
Hello! This script will interactively create an AVR project.
Please type project name: justTest
Creating project justTest...
Listing possible processor choices:
avr-gcc: note: devices natively supported: ata5272 ata5505 ata5702m322 ata5782 [... snipped ...] at90usb646 at90usb647 at90usb82 at94k m3000
Please choose processor (one of above): atmega328p
You chose atmega328p.
Listing possible processor choices (for avrdude):
Valid parts are:
uc3a0512 = AT32UC3A0512
c128 = AT90CAN128
c32 = AT90CAN32
c64 = AT90CAN64
pwm2 = AT90PWM2
pwm216 = AT90PWM216
[... snipped ...]
x64a3 = ATxmega64A3
x64a3u = ATxmega64A3U
x64a4 = ATxmega64A4
x64a4u = ATxmega64A4U
x64b1 = ATxmega64B1
x64b3 = ATxmega64B3
x64c3 = ATxmega64C3
x64d3 = ATxmega64D3
x64d4 = ATxmega64D4
x8e5 = ATxmega8E5
ucr2 = deprecated, use 'uc3a0512'
Please choose processor (one of above): m328p
You chose m328p.
Creating simple blink file - hopefully it compiles.
Patching makefile...
