## READ FIRST
|

- **README** of top directory : https://github.com/tmk/tmk_keyboard/blob/master/README.md
|
||
- **README** of target project(keyboard/converter) directory.
|

Note that you'll need to read **both**.

# Degug Console
|
||
## hid_listen can't recognize 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 on console
|
||
Check:
|
||
- *hid_listen* finds your device. See above.
|
||
- Enable debug with pressing **Magic**+d. 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).
|
||
|
||
## Linux or UNIX like system requires Super User privilege
|
||
Just use 'sudo' to execute *hid_listen* with privilege.
|
||
```
|
||
$ sudo hid_listen
|
||
```
|
||
|
||
Or add an *udev rule* for TMK devices with placing a file in rules directory. The directory may vary on each system.
|
||
|
||
File: /etc/udev/rules.d/52-tmk-keyboard.rules(in case of Ubuntu)
|
||
```
|
||
# tmk keyboard products https://github.com/tmk/tmk_keyboard
|
||
SUBSYSTEMS=="usb", ATTRS{idVendor}=="feed", MODE:="0666"
|
||
```

# Miscellaneous
|
||
## NKRO Doesn't work
|
||
First you have to compile frimware with this build option in `Makefile`.
|
||
|
||
NKRO_ENABLE = yes
|
||
|
||
Try `Magic` **N** command(`LShift+RShift+N` by default) when **NKRO** still doesn't work. You can use this command to toggle between **NKRO** and **6KRO** mode temporarily. In some situations **NKRO** doesn't work you need to switch to **6KRO** mode.
|
||
|
||
If your firmeare built with `BOOTMAGIC_ENABLE` you need to turn its switch on by `BootMagic` **N** command(`Space+N` by default). This setting is stored in EEPROM and keeped over power cycles.
|
||
https://github.com/tmk/tmk_keyboard#boot-magic-configuration---virtual-dip-switch
|
||
|
||
Note that host(in particular BIOS) can force keyboard to turn into **6KRO** mode.
|
||
|
||
|
||
## 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`.

||
|
||
## Pull-up Resistor
|
||
In some case converters needed to have pull-up resistors to work correctly. Place the resistor between VCC and signal line in parallel.
|
||
|
||
For example:
|
||
```
|
||
Keyboard Conveter
|
||
,------.
|
||
5V------+------|VCC |
|
||
| | |
|
||
R | |
|
||
| | |
|
||
Signal--+------|PD0 |
|
||
| |
|
||
GND------------|GND |
|
||
`------'
|
||
R: 1K Ohm resistor
|
||
```
|
||
|
||

|
||
|
||
|
||
## Arduino Micro's pin naming is confusing
|
||
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.

|
||
|
||
|
||
|
||
## Bootloader jump doesn't work
|
||
Properly configure boot section size in Makefile. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.
|
||
- https://github.com/tmk/tmk_keyboard#magic-commands
|
||
- https://github.com/tmk/tmk_keyboard#bootloader
|
||
|
||
```
|
||
# Boot Section Size in *bytes*
|
||
# Teensy halfKay 512
|
||
# Teensy++ halfKay 1024
|
||
# Atmel DFU loader 4096 (TMK Alt Controller)
|
||
# LUFA bootloader 4096
|
||
# USBaspLoader 2048
|
||
OPT_DEFS += -DBOOTLOADER_SIZE=4096
|
||
```
|
||
http://geekhack.org/index.php?topic=12047.msg1292018#msg1292018
|
||
|
||
|
||
## Special Extra key doesn't work(System, Audio control keys)
|
||
You need to define `EXTRAKEY_ENABLE` in **makefile** to use them in TMK.
|
||
```
|
||
EXTRAKEY_ENABLE = yes # Audio control and System control
|
||
```
|
||
http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-60.html#p157919
|
||
|
||
|
||
## Wakeup from sleep doesn't work
|
||
In Windows check `Allow this device to wake the computer` setting in Power **Management property** tab of **Device Manager**. Also check BIOS setting.
|
||
|
||
Pressing any key during sleep should wake host.
|
||
|
||
|
||
## Using Arduino?
|
||
**Note that Arduino pin naming is different from actual chip.** For example, Arduino pin `D0` is not `PD0`. Check circuit with its schematics yourself.
|
||
|
||
- http://arduino.cc/en/uploads/Main/arduino-leonardo-schematic_3b.pdf
|
||
- http://arduino.cc/en/uploads/Main/arduino-micro-schematic.pdf
|
||
|
||
Arduino leonardo and micro have **ATMega32U4** and can be used for TMK, though Arduino bootloader may be a problem.
|
||
|
||
|
||
## Using PF4-7 pins of USB AVR?
|
||
You need to set JTD bit of MCUCR yourself to use PF4-7 as GPIO. Those pins are configured to serve JTAG function by default. MCUs like ATMega*U* or AT90USB* are affeteced with this.
|
||
|
||
If you are using Teensy this isn't needed. Teensy is shipped with JTAGEN fuse bit unprogrammed to disable the function.
|
||
|
||
See this code.
|
||
```
|
||
// JTAG disable for PORT F. write JTD bit twice within four cycles.
|
||
MCUCR |= (1<<JTD);
|
||
MCUCR |= (1<<JTD);
|
||
```
|
||
https://github.com/tmk/tmk_keyboard/blob/master/keyboard/hbkb/matrix.c#L67
|
||
|
||
And read **26.5.1 MCU Control Register – MCUCR** of ATMega32U4 datasheet.
|
||
|
||
|
||
## Adding LED indicators of Lock keys
|
||
You need your own LED indicators for CapsLock, ScrollLock and NumLock? See this post.
|
||
|
||
http://deskthority.net/workshop-f7/tmk-keyboard-firmware-collection-t4478-120.html#p191560
|
||
|
||
## Program Arduino Micro/Leonardo
|
||
Push reset button and then run command like this within 8 seconds.
|
||
|
||
```
|
||
avrdude -patmega32u4 -cavr109 -b57600 -Uflash:w:adb_usb.hex -P/dev/ttyACM0
|
||
```
|
||
|
||
Device name will vary depending on your system.
