## How do I test my keyboard? :id=testing
|
|
|
|
Testing your keyboard is usually pretty straightforward. Press every single key and make sure it sends the keys you expect. You can use [QMK Configurator](https://config.qmk.fm/#/test/)'s test mode to check your keyboard, even if it doesn't run QMK.
|
|
|
|
## Safety Considerations
|
|
|
|
You probably don't want to "brick" your keyboard, making it impossible
|
|
to rewrite firmware onto it. Here are some of the parameters to show
|
|
what things are (and likely aren't) too risky.
|
|
|
|
- If your keyboard map does not include RESET, then, to get into DFU
|
|
mode, you will need to press the reset button on the PCB, which
|
|
requires unscrewing the bottom.
|
|
- Messing with tmk_core / common files might make the keyboard
|
|
inoperable
|
|
- Too large a .hex file is trouble; `make dfu` will erase the block,
|
|
test the size (oops, wrong order!), which errors out, failing to
|
|
flash the keyboard, leaving it in DFU mode.
|
|
- To this end, note that the maximum .hex file size on Planck is
|
|
7000h (28672 decimal)
|
|
|
|
```
|
|
Linking: .build/planck_rev4_cbbrowne.elf [OK]
|
|
Creating load file for Flash: .build/planck_rev4_cbbrowne.hex [OK]
|
|
|
|
Size after:
|
|
text data bss dec hex filename
|
|
0 22396 0 22396 577c planck_rev4_cbbrowne.hex
|
|
```
|
|
|
|
- The above file is of size 22396/577ch, which is less than
|
|
28672/7000h
|
|
- As long as you have a suitable alternative .hex file around, you
|
|
can retry, loading that one
|
|
- Some of the options you might specify in your keyboard's Makefile
|
|
consume extra memory; watch out for BOOTMAGIC_ENABLE,
|
|
MOUSEKEY_ENABLE, EXTRAKEY_ENABLE, CONSOLE_ENABLE, API_SYSEX_ENABLE
|
|
- DFU tools do /not/ allow you to write into the bootloader (unless
|
|
you throw in extra fruit salad of options), so there is little risk
|
|
there.
|
|
- EEPROM has around a 100000 write cycle. You shouldn't rewrite the
|
|
firmware repeatedly and continually; that'll burn the EEPROM
|
|
eventually.
|
|
|
|
## NKRO Doesn't work
|
|
First you have to compile firmware with this build option `NKRO_ENABLE` in **Makefile**.
|
|
|
|
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, in particular when you are in BIOS.
|
|
|
|
If your firmware 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 kept over power cycles.

## TrackPoint Needs Reset Circuit (PS/2 Mouse Support)
|
|
Without reset circuit you will have inconsistent result due to improper initialize of the hardware. See circuit schematic of TPM754.

## Can't Read Column of Matrix Beyond 16
|
|
Use `1UL<<16` instead 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 [16 bit] 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`.

|
|
## Special Extra Key Doesn't Work (System, Audio Control Keys)
|
|
You need to define `EXTRAKEY_ENABLE` in `rules.mk` to use them in QMK.
|
|
|
|
```
|
|
EXTRAKEY_ENABLE = yes # Audio control and System control
|
|
```
|
|
|
|
## 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-micro-schematic.pdf
|
|
|
|
Arduino Leonardo and micro have **ATMega32U4** and can be used for TMK, though Arduino bootloader may be a problem.
|
|
|
|
## Enabling JTAG
|
|
|
|
By default, the JTAG debugging interface is disabled as soon as the keyboard starts up. JTAG-capable MCUs come from the factory with the `JTAGEN` fuse set, and it takes over certain pins of the MCU that the board may be using for the switch matrix, LEDs, etc.
|
|
|
|
If you would like to keep JTAG enabled, just add the following to your `config.h`:
|
|
|
|
```c
|
|
#define NO_JTAG_DISABLE
|
|
```
|
|
|
|
## USB 3 Compatibility
|
|
I heard some people have a problem with USB 3 port, try USB 2 port.
|
|
|
|
|
|
## Mac Compatibility
|
|
### OS X 10.11 and Hub

## Problem on BIOS (UEFI)/Resume (Sleep & Wake)/Power Cycles
|
|
Some people reported their keyboard stops working on BIOS and/or after resume(power cycles).
|
|
|
|
As of now root of its cause is not clear but some build options seem to be related. In Makefile try to disable those options like `CONSOLE_ENABLE`, `NKRO_ENABLE`, `SLEEP_LED_ENABLE` and/or others.
