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WINAVR is obsolete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.

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.
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.

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.

To turn on NKRO by default see this fix. https://github.com/shayneholmes/tmk_keyboard/commit/b8375a0

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.

Can't read comlumn of matrix beyond 16

Use 1UL<<16 intead of 1<<16 in read_cols() in matrix.h when your columns goes beyond 16.

In C 1 means one of int type which is 16bit in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say 1<<16. You have to use unsigned long type with 1UL.
