# Build
## 'make clean' needs after changing config.h
To build with new **config.h** you need

    $ make clean

## WINAVR is obsolete
It is no longer recommended and may cause some problem.
See [Issue #99](https://github.com/tmk/tmk_keyboard/issues/99).



# Degug Console
## hid_listen can't find device
When debug console of your device is not ready you will see like this:

    Waiting for device:.........

once the device is pluged in then *hid_listen* finds it you will get this message:

    Waiting for new device:.........................
    Listening:

Check if you can't get this 'Listening:' message:
- build with `CONSOLE_ENABLE=yes` in **Makefile**.

## Can't get message from console
Check:
- connect the device to *hid_listen*. See above.
- push **LShift+RShift+d** to enable debug. See [Magic Commands](https://github.com/tmk/tmk_keyboard#magic-commands).
- set `debug_enable=yes` usually in `matrix_init()` in **matrix.c**.
- try using 'print' function instead of debug print. See **common/print.h**.
- disconnect other devices with console function. See [Issue #97](https://github.com/tmk/tmk_keyboard/issues/97).

# Miscellaneous
## NKRO Doesn't work
Build with this option of Makefile

    NKRO_ENABLE = yes

And use `Magic` command **N** to toggle NKRO feature.
At this time NKRO is not used by default even if it is build with `NKRO_ENABLE`, you still need the `Magic`.


## TrackPoint needs reset circuit(PS/2 mouse support)
Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.
