2 ## 'make clean' needs after changing config.h
3 To build with new **config.h** you need
8 It is no longer recommended and may cause some problem.
9 See [Issue #99](https://github.com/tmk/tmk_keyboard/issues/99).
11 ## USB stack: LUFA or PJRC?
12 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?).
14 See also [Issue #50](https://github.com/tmk/tmk_keyboard/issues/50) and [Issue #58](https://github.com/tmk/tmk_keyboard/issues/58).
17 ## hid_listen can't find device
18 When debug console of your device is not ready you will see like this:
20 Waiting for device:.........
22 once the device is pluged in then *hid_listen* finds it you will get this message:
24 Waiting for new device:.........................
27 Check if you can't get this 'Listening:' message:
28 - build with `CONSOLE_ENABLE=yes` in **Makefile**.
30 ## Can't get message from console
32 - connect the device to *hid_listen*. See above.
33 - push **LShift+RShift+d** to enable debug. See [Magic Commands](https://github.com/tmk/tmk_keyboard#magic-commands).
34 - set `debug_enable=yes` usually in `matrix_init()` in **matrix.c**.
35 - try using 'print' function instead of debug print. See **common/print.h**.
36 - disconnect other devices with console function. See [Issue #97](https://github.com/tmk/tmk_keyboard/issues/97).
42 Build with this option of Makefile
46 And use `Magic` command **N** to toggle NKRO feature.
47 At this time NKRO is not used by default even if it is build with `NKRO_ENABLE`, you still need the `Magic`.
49 To turn on NKRO by default see this fix.

66 Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

72 ## Can't read comlumn of matrix beyond 16
73 Use `1UL<<16` intead of `1<<16` in `read_cols()` in **matrix.h** when your columns goes beyond 16.
75 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`.
