# HHKB Alternate Controller (YANG HHKB BLE Mod)
|
|
|
|
|
|
|
|
An alternative controler for the HHKB designed by YANG (yangdigi)
|
|
based on the hasu controller.
|
|
|
|
* Keyboard Maintainer: [Kan-Ru Chen](https://github.com/kanru)
|
|
* Hardware Supported: YANG HHKB BLE Controller
|
|
* Hardware Availability: https://kbdfans.com/products/hhkb-ble-mod-upgrade-module
|
|
|
|
Make example for this keyboard (after setting up your build environment):
|
|
|
|
make hhkb/yang:default
|
|
|
|
To flash, first boot your keyboard into bootloader (hold ESC and attach usb cable)
|
|
then a virtual USB storage should appear. You can copy the `hhkb_yang_default.bin`
|
|
file to the virtual USB storage and override the `HHKB_BLE.BIN` file in there.
|
|
|
|
Make sure to unmount and eject the virtual USB storage.
|
|
|
|

|
|
|
|
- [x] QMK (via USB)
|
|
- [x] Bluetooth (BLE)

|
|
- [x] Special commands
|

|
|
|
|
## Entering flash mode
|
|
|
|
Different ways to enter flash mode:
|
|
|
|
* Press and hold the ESC key. Insert the USB cable to enter the flash
|
|
mode. When the OS shows the drive disk, you can release the key.
|
|
|
|
* Use the magic command LSHIFT+RSHIFT+B to reboot to bootloader then
|
|
quickly hold the ESC key.
|
|
|
|
If you reflash the wrong firmware or did not reflash successfully, you
|
|
can no longer enter the flash mode, especially the wireless keyboard
|
|
with battery. You need to turn off the keyboard's power switch, and
|
|
re-enter the flash mode, reflash the correct firmware.
|
|
|
|
After entering the bootloader(flash mode), three indicators on the top
|
|
right of the HHKB BLE controller will flash. LED3(green) will flash
|
|
quickly when writing firmware to the controller.
|
|
|
|
If these three leds are not soldered or your hhkb case is black, you
|
|
can't know their status, but you can still see LED3 under the right
|
|
USB port.

|
|
|
## How to reliably flash LUFA MassStorage bootloader on Linux
|
|
|
|
The FAT filesystem on Linux very often cannot flush the write cache,
|
|
leading to broken firmware in the flash.
|
|
|
|
We can use `dd` to write to the virtual block storage directly to
|
|
bypass the vfs layer.
|
|
|
|
```
|
|
dd if=FLASH.bin of=<path of virtual block device> seek=4
|
|
```
|
|
|
|
Skip 4 sectors because the default sector size of the virtual device
|
|
and dd is 512 bytes and the emulated flash file starts at 5th sector.
|
|
|
|
## How to find the path of the virtual block device
|
|
|
|
After the keyboard boots into flash mode, on Linux system you should
|
|
be able to find the block device in `dmesg` logs.
|
|
|
|
For exmaple if you type
|
|
|
|
```
|
|
sudo dmesg
|
|
```
|
|
|
|
You should find something like
|
|
|
|
```
|
|
[357885.143593] usb 1-1.4: USB disconnect, device number 24

[357886.859528] sd 0:0:0:0: [sdx] Attached SCSI removable disk
|
|
```
|
|
|
|
The `sdx` is the block device name and the full path is at `/dev/sdx`
|
|
The above flash command will become
|
|
|
|
```
|
|
dd if=FLASH.bin of=/dev/sdx seek=4
|
|
```
|
|
|
|
**Caution**: if set to incorrect device it may wipe out
|
|
your actual disk.
