READ FIRST

In short,

$ make [-f Makefile.<variant>] [KEYMAP=...] clean
$ make [-f Makefile.<variant>] [KEYMAP=...]
$ make [-f Makefile.<variant>] [KEYMAP=...] dfu

Do 'make clean' before 'make'

You'll need make clean after you edit config.h or change options like KEYMAP.

Frist remove all files made in previous build,

$ make clean

then build new frimware.

$ make [KEYMAP=...]

Also you can always try make clean when you get other strange result during build.

WINAVR is obsolete

It is no longer recommended and may cause some problem. See Issue #99.

USB stack: LUFA or PJRC?

Use LUFA.

PJRC stack won't be supported actively anymore. There is no reason to hesitate to use LUFA except for binary size(about 1KB lager?). But PJRC is still very useful for debug and development purpose. See also Issue #50 and Issue #58.

Edit configuration but not change

Try these.

1. make clean

This will be needed when you edit config.h.

2. Remove Drivers from Device Manager(Windows)

Windows only. Linux, OSX and other OS's doesn't require this. It looks like Windows keeps using driver installed when device was connected first time even after the device changes its configuration. To load proper drivers for new configuration you need to remove existent drivers from Drvice Manager.

You will need this after editing CONSOLE_ENABLE, NKRO_ENABLE, EXTRAKEY_ENABLE or MOUSEKEY_ENABLE option in Makefile.

USB VID and PID

You can use any ID you want with editing config.h. Using any presumably unused ID will be no problem in fact except for very least chance of collision with other product.

For example TMK uses following numbers by default.

keyboard:
hhkb: FEED:CAFE
gh60: FEED:6060

converter:
x68k: FEED:6800
ps2: FEED:6512
adb: FEED:0ADB
ibm4704: FEED:4704
pc98: FEED:9898

Also see this. https://github.com/tmk/tmk_keyboard/issues/150

You can buy a really unique VID:PID here. I don't think you need this for personal use.
