# Hey Emacs, this is a -*- makefile -*-
#----------------------------------------------------------------------------
# avr-gcc Makefile
#
# by Steffen Vogel <info@steffenvogel.de>
#
# Released to the Public Domain - Credits to:
# Eric B. Weddington, Jörg Wunsch, Peter Fleury, Tim Henigan Colin O'Flynn,
# Reiner Patommel, Markus Pfaff, Sander Pool, Frederik Rouleau, Carlos Lamas
#----------------------------------------------------------------------------
# On command line:
#
# make all = Make software
#
# make clean = Clean out built project files
#
# make program = Download the hex file to the device, using avrdude
# Please customize the avrdude settings below first!
#
# make filename.s = Just compile filename.c into the assembler code only
#
# make filename.i = Create a preprocessed source file for use in submitting
# bug reports to the GCC project.
#
# To rebuild project do "make clean" then "make all".
#----------------------------------------------------------------------------
#------------------------------ General Options -----------------------------
# MCU name
MCU = atmega8
# Processor frequency
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
# Typical values are:
F_CPU = 12000000
#F_CPU = 1843200
#F_CPU = 2000000
#F_CPU = 3686400

General Description:
This file is an example configuration (with inline documentation) for the USB
driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
wire the lines to any other port, as long as D+ is also wired to INT0 (or any
other hardware interrupt, as long as it is the highest level interrupt, see
section at the end of this file).
+ To create your own usbconfig.h file, copy this file to your project's
+ firmware source directory) and rename it to "usbconfig.h".
+ Then edit it accordingly.

/* This is the port where the USB bus is connected. When you configure it to
* "B", the registers PORTB, PINB and DDRB will be used.

/* This is the bit number in USB_CFG_IOPORT where the USB D- line is connected.
* This may be any bit in the port.
*/
#define USB_CFG_DPLUS_BIT 1
/* This is the bit number in USB_CFG_IOPORT where the USB D+ line is connected.
* This may be any bit in the port. Please note that D+ must also be connected
* to interrupt pin INT0! [You can also use other interrupts, see section
* "Optional MCU Description" below, or you can connect D- to the interrupt, as
* it is required if you use the USB_COUNT_SOF feature. If you use D- for the
* interrupt, the USB interrupt will also be triggered at Start-Of-Frame
* markers every millisecond.]

/* ------------------- Fine Control over USB Descriptors ------------------- */

* runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
* information about this function.
* Descriptor handling is configured through the descriptor's properties. If
* no properties are defined or if they are 0, the default descriptor is used.
* Possible properties are:
* + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
* at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
* used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
* you want RAM pointers.
* + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
* in static memory is in RAM, not in flash memory.
* + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
* the driver must know the descriptor's length. The descriptor itself is
* found at the address of a well known identifier (see below).
* List of static descriptor names (must be declared PROGMEM if in flash):
* char usbDescriptorDevice[];
* char usbDescriptorConfiguration[];
* char usbDescriptorHidReport[];
* char usbDescriptorString0[];
* int usbDescriptorStringVendor[];
* int usbDescriptorStringDevice[];
* int usbDescriptorStringSerialNumber[];
* Other descriptors can't be provided statically, they must be provided
* dynamically at runtime.
*
* Descriptor properties are or-ed or added together, e.g.:
* #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
*
* The following descriptors are defined:
* USB_CFG_DESCR_PROPS_DEVICE
* USB_CFG_DESCR_PROPS_CONFIGURATION
* USB_CFG_DESCR_PROPS_STRINGS
* USB_CFG_DESCR_PROPS_STRING_0
* USB_CFG_DESCR_PROPS_STRING_VENDOR
* USB_CFG_DESCR_PROPS_STRING_PRODUCT
* USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER
* USB_CFG_DESCR_PROPS_HID
* USB_CFG_DESCR_PROPS_HID_REPORT
* USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
*
* Note about string descriptors: String descriptors are not just strings, they
* are Unicode strings prefixed with a 2 byte header. Example:
* int serialNumberDescriptor[] = {
* USB_STRING_DESCRIPTOR_HEADER(6),
* 'S', 'e', 'r', 'i', 'a', 'l'
* };
