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?
14 **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.
15 See also [Issue #50](https://github.com/tmk/tmk_keyboard/issues/50) and [Issue #58](https://github.com/tmk/tmk_keyboard/issues/58).
18 ## Edit configuration but not change
21 This will be needed when you edit **config.h**.
23 ### 2. Remove Drivers from Device Manager(Windows)
24 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**.
26 You will need this after editing `CONSOLE_ENABLE`, `NKRO_ENABLE`, `EXTRAKEY_ENABLE` or `MOUSEKEY_ENABLE` option in **Makefile**.
30 ## Power key doesn't work
31 Use `KC_PWR` instead of `KC_POWER` or vice versa.
32 - `KC_PWR` works with Windows and Linux, not with OSX.
33 - `KC_POWER` works with OSX and Linux, not with Windows.

40 ## hid_listen can't find device
41 When debug console of your device is not ready you will see like this:
43 Waiting for device:.........
45 once the device is pluged in then *hid_listen* finds it you will get this message:
47 Waiting for new device:.........................
50 Check if you can't get this 'Listening:' message:
51 - build with `CONSOLE_ENABLE=yes` in **Makefile**.
53 ## Can't get message from console
55 - connect the device to *hid_listen*. See above.
56 - push **LShift+RShift+d** to enable debug. See [Magic Commands](https://github.com/tmk/tmk_keyboard#magic-commands).
57 - set `debug_enable=yes` usually in `matrix_init()` in **matrix.c**.
58 - try using 'print' function instead of debug print. See **common/print.h**.
59 - disconnect other devices with console function. See [Issue #97](https://github.com/tmk/tmk_keyboard/issues/97).
65 1. Build with this option of Makefile
69 2. After boot keyboard may be in **boot mode**(6KRO), you will need to replug keyboard to enable NKRO.
71 3. Or use `Magic` **N** command to toggle NKRO function.(`LShift+RShift+N` by default)
75 ## TrackPoint needs reset circuit(PS/2 mouse support)
76 Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

82 ## Can't read comlumn of matrix beyond 16
83 Use `1UL<<16` intead of `1<<16` in `read_cols()` in **matrix.h** when your columns goes beyond 16.
85 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`.

92 In some case converters needed to have pull-up resistors to work correctly. Place the resistor between VCC and signal line in parallel.
101 Signal--+------|PD0 |
103 GND------------|GND |
109 ## Arduino Micro's pin naming is confusing
110 Note that Arduino Micro PCB marking is different from real AVR port name. D0 of Arduino Micro is not PD0, PD0 is D3. Check schematic yourself.

115 ## Bootloader jump doesn't work
116 Properly configure boot section size in Makefile. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.
117 - https://github.com/tmk/tmk_keyboard#magic-commands
118 - https://github.com/tmk/tmk_keyboard#bootloader
121 # Boot Section Size in *bytes*
123 # Teensy++ halfKay 1024
124 # Atmel DFU loader 4096 (TMK Alt Controller)
125 # LUFA bootloader 4096
127 OPT_DEFS += -DBOOTLOADER_SIZE=4096

132 ## Special Extra key doesn't work(System, Audio control keys)
133 You need to define `EXTRAKEY_ENABLE` in **makefile** to use them in TMK.
135 EXTRAKEY_ENABLE = yes # Audio control and System control

140 ## Wakeup from sleep doesn't work
141 In Windows check `Allow this device to wake the computer` setting in Power **Management property** tab of **Device Manager**. Also check BIOS setting.
143 Pressing any key during sleep should wake host.
