DeskHop v0.61 - Promoted RC to Stable 

- Single unified firmware binary
- Improved support for NKRO keyboards
- Report mode default for keyboard port
- Improved consumer control parser for variable
  data types (media keys should be better supported)
- System control forwarding
- Improved HID parser
- Web UI to configure instead of keyboard shortcuts
- Firmware upgrade while the device remains functional
- Only one end will need upgrade, the other will get it automatically
- No need to recompile to set most settings
- Improved UART routines to use DMA, more reliable link
- Fixed a bunch of bugs and issues

## Using pre-built images
additionally, to rebuild web UI check webconfig/ and execute ```./render.py```, you'll need jinja2 installed.
Alternatively, you can use the [pre-built images](binaries/). Take the Pico board that goes to slot A on the PCB and hold the on-board button while connecting the cable.
To rebuild the disk, check disk/ folder and run ```./create.sh```, tweak to your system if needed. You'll need **dosfstools** (to provide mkdosfs),
It should appear as a USB drive on your system. Copy the corresponding board_A.uf2 file there and repeat the same with B.
## Using a pre-built image
Alternatively, you can use the [pre-built images](https://github.com/hrvach/deskhop/releases). Since version 0.6 there is only a single universal image. You need the .uf2 file which you simply copy to the device in one of the following ways:
## Upgrading firmware
Option 1 - Open the case, hold the button while connecting each Pico and copy the right uf2 to it.
**Option 1** - (firmware 0.6 and later) Put the device in "config mode" by simultaneously pressing **left shift + right shift + c + o**. Device your keyboard is plugged into will reboot and turn into a USB drive called "DESKHOP". All you need to do is copy the .uf2 file to it. Once image is verified, device will flash and reboot, then proceed to upgrade the other board. During this operation the led will blink. Once it's done, it will write flash and reboot, completing the operation.
Option 2 - Switch a board to BOOTSEL mode by using a special key combination (listed below).
_Note_ - This is not an actual generic USB drive, you can't use it to copy files to it.
This will make the corresponding Pico board enter the bootloader upgrade mode and act as USB flash drive. Now you can drag-and-drop the .uf2 file to it (you might need to plug in your mouse directly).
**Option 2** - Using the ROM bootloader - hold the on-board button while connecting each Pico and copy the uf2 to the flash drive that appears. Images later than 0.6 support holding the button without having to fiddle around the power supply, but the "hold button while plugging" should always work, regardless of device state.

## Hardware
[The circuit](schematics/DeskHop_v1.1.pdf) is based on two Raspberry Pi Pico boards, chosen because they are cheap (4.10 € / pc), can be hand soldered and most suppliers have them in stock.
The Picos are connected using UART and separated by an Analog Devices ADuM1201 dual-channel digital isolator (~3€) or a much cheaper, faster and pin-compatible TI ISO7721DR (~1.5€).
The Picos are connected using UART and separated by an Analog Devices ADuM1201 dual-channel digital isolator (~3€) or a much cheaper, faster and pin-compatible TI ISO7721DR (~1.5€) which is the preferred choice.
While they normally don't have support for dual USB, thanks to an [amazing project](https://github.com/sekigon-gonnoc/Pico-PIO-USB) where USB is implemented using the programmable IO wizardry found in RP2040, there is support for it to act both as an USB host and device.
## PCB [updated]
To keep things as simple as possible for DIY builds, the traces were kept on one side and the number of parts kept to a theoretical minimum.

### Multiple screens per output
Windows and Mac have issues with multiple screens and absolute positioning, so workarounds are needed (still experimental). Your main screens need to be in the middle, and secondary screen(s) on the edges. Move the mouse to the screen with multiple desktops and press *right shift + backspace + 2* if you have 2 desktops and *right shift + backspace + 7, 8 or 9* depending on your OS (Linux, Windows, Mac).
Windows and Mac have issues with multiple screens and absolute positioning, so workarounds are needed (still experimental). There is a better workaround under construction, but for now you have to set the operating system for each output and number of screens.
Your main screens need to be in the middle, and secondary screen(s) on the edges. To configure the actual options, open the web configuration page for your device.

### Other configuration
### Web configuration mode
Mouse speed can now be configured per output screen and per axis. If you have multiple displays under Linux, your X speed might be too fast, so you need to configure it in user_config.h and rebuild. In the future, this will be configurable without having to do that.
Starting with fw 0.6, an improved configuration mode is introduced. To configure your device, follow these instructions:
1. Press Left Shift + Right Shift + C + O - your device will reboot and enter configuration mode (on the side your keyboard is plugged into). LED will keep blinking during the configuration session.
2. A new USB drive will appear named "DESKHOP" with a single file, config.htm
3. Open that file with Chromium / Chrome. Unfortunately FF is not supported right now, since they avoid implementing WebHID.
4. Click connect and allow deskhop device to pair.
![Image](img/connect-dialog.png)
5. Configure the options as you wish and click save to write to device.
6. Click "exit" in the menu to leave configuration mode for added safety.

Q: Why not simply create a nice online web page like Via instead of dealing with this weird USB drive thing?
A: Loading javascript from a random online location that interacts with your input devices is a potential security risk. The configuration web page is local only and nothing is ever loaded externally.
<details closed>
<summary>Linux doesn't see device? Click here.</summary>
Q: Chromium on Linux doesn't work.
A: You probably need to tweak /dev permissions or create a corresponding udev rules file and make sure your user is in the right group, like so:
/etc/udev/rules.d/99-deskhop.rules
```
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="c000", GROUP="plugdev", MODE="0660"
```
</details><br />
Please note the config web page is not "weird" because of deliberate obfuscation - it's self-decompressing due to very limited storage. Entire source is 100% open and a part of this repo. You are encouraged to rebuild everything yourself.

Some features are missing on purpose, despite the fact it would make the device easier to use or simpler to configure. Here is a quick breakdown of these decisions:
- There is no copy-paste or *any* information sharing between systems. This prevents information leakage.
- No webhid device management or any inbound connectivity from the output computers, with the only exception of standard keyboard LED on/off messages, hard limited to 1 byte of data.
- No webhid device management without explicit user consent. No inbound connectivity from the output computers, with the only exception of standard keyboard LED on/off messages and hard limited to 1 byte of data.
- No FW upgrade triggering from the outputs. Only explicit and deliberate user action through a special keyboard shortcut may do that.
- No plugged-in keyboard/mouse custom endpoints are exposed or information forwarded towards these devices. Their potential vulnerabilities are effectively firewalled from the computer.
- No input history is allowed to be retained.
- No device-initiated keystrokes, for any reason. Only thing that comes out is what you type/trigger.
- Outputs are physically separated and galvanically isolated with a minimal isolation voltage of 2kV.
- All packets exchanged between devices are of fixed length, no code is transferred and no raw config exchange of any kind can take place.
- There is no bluetooth or wifi, networking, Internet access, usb drives etc.
- All packets exchanged between devices are of fixed length, config options transferred are limited to a short list. Most options are read-only. Cross-device firmware upgrades can be disabled.
- There is no bluetooth or wifi, networking, Internet access, etc.
- No connected computer is considered trusted under any circumstances.
- Configuration mode is automatically disabled after a period of inactivity.
- Entirety of the code is open source, without any binary blobs and thoroughly commented to explain its purpose. I encourage you to never trust anyone and always make sure you know what you are running by doing a manual audit.

- Windows 10 broke HID absolute coordinates behavior in KB5003637, so you can't use more than 1 screen on Windows (mouse will stay on the main screen). There is an experimental workaround with a better one on the way.
- Code needs cleanup, some refactoring etc.
- Not tested with a wide variety of devices, I don't know how it will work with your hardware. There is a reasonable chance things might not work out-of-the-box.
- Advanced keyboards (with knobs, extra buttons or sliders) will probably face issues where this additional hardware doesn't work.
- Super-modern mice with 300 buttons might see some buttons not work as expected.
- NOTE: Both computers need to be connected and provide power to the USB for this to work (as each board gets powered by the computer it plugs into). Many desktops and laptops will provide power even when shut down nowadays. If you need to run with one board fully disconnected, you should be able to use a USB hub to plug both keyboard and mouse to a single port.

So, what's the deal with all the enthusiasm? I can't believe it - please allow me to thank you all! I've never expected this kind of interest in a simple personal project, so the initial features are pretty basic (just like my cooking skills) and mostly cover my own usecase. Stay tuned for firmware updates that should bring wider device compatibility, more features and less bugs. As this is a hobby project, I appreciate your understanding for being time-constrained and promise to do the best I can.
Planned features:
- ~~Proper TinyUSB host integration~~ (done)
- ~~HID report protocol parsing, not just boot protocol~~ (mostly done)
- ~~Support for unified dongle receivers~~
- ~~Support for USB hubs and single-sided operation~~
- ~~Configurable screens (done)~~
- ~~Permament configuration stored in flash~~
- Better support for keyboards with knobs and mice with mickeys
- Unified firmware for both Picos
- Better workarounds for multiscreen windows and macos
- Transparent / Gaming mode
- Support for more than 2 outputs
- Improvements on the configuration UI
- ... and more!
Working on a *lite* version which provides basic functionality with just a single Pico W board, lowering the cost even further and enabling you to try it out even with no added hardware or PCB.

## Sponsor / donate
I'm NOT doing this for profit or any other reason except to try and help people by creating a better working environment for everyone.
I have, however, decided to accept donations for a single purpose only - to buy some keyboards/mice with media keys, buttons, nkro and other weird stuff people reported issues with in order to fix bugs, improve the state of the project and provide a better user experience overall.
Having said that, if you want to support the project, you can use this link:

/**
* \defgroup pico_btstack pico_btstack
* \brief Integration/wrapper libraries for <a href="https://github.com/bluekitchen/btstack">BTstack</a>
* the documentation for which is <a href="https://bluekitchen-gmbh.com/btstack/">here</a>.
*
* A supplemental license for BTstack (in addition to the stock BTstack licensing terms) is provided <a href="https://github.com/raspberrypi/pico-sdk/blob/master/src/rp2_common/pico_btstack/LICENSE.RP">here</a>.
*
* The \c \b pico_btstack_ble library adds the support needed for Bluetooth Low Energy (BLE). The \c \b pico_btstack_classic library adds the support needed for Bluetooth Classic.
* You can link to either library individually, or to both libraries thus enabling dual-mode support provided by BTstack.
*
* To use BTstack you need to provide a \c btstack_config.h file in your source tree and add its location to your include path.
* The BTstack configuration macros \c ENABLE_CLASSIC and \c ENABLE_BLE are defined for you when you link the \c pico_btstack_classic and \c pico_btstack_ble libraries respectively, so you should not define them yourself.
*
* For more details, see <a href="https://bluekitchen-gmbh.com/btstack/develop/#how_to/">How to configure BTstack</a> and the relevant <a href="https://github.com/raspberrypi/pico-examples#pico-w-bluetooth">pico-examples</a>.
*
* The follow libraries are provided for you to link.
* * \c \b pico_btstack_ble - Adds Bluetooth Low Energy (LE) support.
* * \c \b pico_btstack_classic - Adds Bluetooth Classic support.
* * \c \b pico_btstack_sbc_encoder - Adds Bluetooth Sub Band Coding (SBC) encoder support.
* * \c \b pico_btstack_sbc_decoder - Adds Bluetooth Sub Band Coding (SBC) decoder support.
* * \c \b pico_btstack_bnep_lwip - Adds Bluetooth Network Encapsulation Protocol (BNEP) support using LwIP.
* * \c \b pico_btstack_bnep_lwip_sys_freertos - Adds Bluetooth Network Encapsulation Protocol (BNEP) support using LwIP with FreeRTOS for NO_SYS=0.
*
* \note The CMake function pico_btstack_make_gatt_header can be used to run the BTstack compile_gatt tool to make a GATT header file from a BTstack GATT file.
*
* \sa pico_btstack_cyw43 in pico_cyw43_driver, which adds the cyw43 driver support needed for BTstack including BTstack run loop support.

/** \file pico/cyw43_arch.h
* \defgroup pico_cyw43_arch pico_cyw43_arch
*
* Architecture for integrating the CYW43 driver (for the wireless on Pico W) and lwIP (for TCP/IP stack) into the SDK. It is also necessary for accessing the on-board LED on Pico W
*
* Both the low level \c cyw43_driver and the lwIP stack require periodic servicing, and have limitations
* on whether they can be called from multiple cores/threads.
*
* \c pico_cyw43_arch attempts to abstract these complications into several behavioral groups:
*
* * \em 'poll' - This not multi-core/IRQ safe, and requires the user to call \ref cyw43_arch_poll periodically from their main loop
* * \em 'thread_safe_background' - This is multi-core/thread/task safe, and maintenance of the driver and TCP/IP stack is handled automatically in the background
* * \em 'freertos' - This is multi-core/thread/task safe, and uses a separate FreeRTOS task to handle lwIP and and driver work.
*
* As of right now, lwIP is the only supported TCP/IP stack, however the use of \c pico_cyw43_arch is intended to be independent of
* the particular TCP/IP stack used (and possibly Bluetooth stack used) in the future. For this reason, the integration of lwIP
* is handled in the base (\c pico_cyw43_arch) library based on the #define \ref CYW43_LWIP used by the \c cyw43_driver.
*
* \note As of version 1.5.0 of the Raspberry Pi Pico SDK, the \c pico_cyw43_arch library no longer directly implements
* the distinct behavioral abstractions. This is now handled by the more general \ref pico_async_context library. The
* user facing behavior of pico_cyw43_arch has not changed as a result of this implementation detail, however pico_cyw43_arch
* is now just a thin wrapper which creates an appropriate async_context and makes a simple call to add lwIP or cyw43_driver support
* as appropriate. You are free to perform this context creation and adding of lwIP, cyw43_driver or indeed any other additional
* future protocol/driver support to your async_context, however for now pico_cyw43_arch does still provide a few cyw43_ specific (i.e. Pico W)
* APIs for connection management, locking and GPIO interaction.
*
* \note The connection management APIs at least may be moved
* to a more generic library in a future release. The locking methods are now backed by their \ref pico_async_context equivalents, and
* those methods may be used interchangeably (see \ref cyw43_arch_lwip_begin, \ref cyw43_arch_lwip_end and \ref cyw43_arch_lwip_check for more details).
*
* \note For examples of creating of your own async_context and addition of \c cyw43_driver and \c lwIP support, please
* refer to the specific source files \c cyw43_arch_poll.c, \c cyw43_arch_threadsafe_background.c and \c cyw43_arch_freertos.c.
*
* Whilst you can use the \c pico_cyw43_arch library directly and specify \ref CYW43_LWIP (and other defines) yourself, several
* other libraries are made available to the build which aggregate the defines and other dependencies for you:
*
* * \b pico_cyw43_arch_lwip_poll - For using the RAW lwIP API (in `NO_SYS=1` mode) without any background processing or multi-core/thread safety.
*
* The user must call \ref cyw43_arch_poll periodically from their main loop.
*
* This wrapper library:
* - Sets \c CYW43_LWIP=1 to enable lwIP support in \c pico_cyw43_arch and \c cyw43_driver.
* - Sets \c PICO_CYW43_ARCH_POLL=1 to select the polling behavior.
* - Adds the \c pico_lwip as a dependency to pull in lwIP.
*
* * \b pico_cyw43_arch_lwip_threadsafe_background - For using the RAW lwIP API (in `NO_SYS=1` mode) with multi-core/thread safety, and automatic servicing of the \c cyw43_driver and
* lwIP in background.
*
* Calls into the \c cyw43_driver high level API (cyw43.h) may be made from either core or from lwIP callbacks, however calls into lwIP (which
* is not thread-safe) other than those made from lwIP callbacks, must be bracketed with \ref cyw43_arch_lwip_begin and \ref cyw43_arch_lwip_end. It is fine to bracket
* calls made from within lwIP callbacks too; you just don't have to.
*
* \note lwIP callbacks happen in a (low priority) IRQ context (similar to an alarm callback), so care should be taken when interacting
* with other code.
*
* This wrapper library:
* - Sets \c CYW43_LWIP=1 to enable lwIP support in \c pico_cyw43_arch and \c cyw43_driver
* - Sets \c PICO_CYW43_ARCH_THREADSAFE_BACKGROUND=1 to select the thread-safe/non-polling behavior.
* - Adds the pico_lwip as a dependency to pull in lwIP.
*
*
* This library \em can also be used under the RP2040 port of FreeRTOS with lwIP in `NO_SYS=1` mode (allowing you to call \c cyw43_driver APIs
* from any task, and to call lwIP from lwIP callbacks, or from any task if you bracket the calls with \ref cyw43_arch_lwip_begin and \ref cyw43_arch_lwip_end. Again, you should be
* careful about what you do in lwIP callbacks, as you cannot call most FreeRTOS APIs from within an IRQ context. Unless you have good reason, you should probably
* use the full FreeRTOS integration (with `NO_SYS=0`) provided by \c pico_cyw43_arch_lwip_sys_freertos.
*
* * \b pico_cyw43_arch_lwip_sys_freertos - For using the full lwIP API including blocking sockets in OS (`NO_SYS=0`) mode, along with with multi-core/task/thread safety, and automatic servicing of the \c cyw43_driver and
* the lwIP stack.
*
* This wrapper library:
* - Sets \c CYW43_LWIP=1 to enable lwIP support in \c pico_cyw43_arch and \c cyw43_driver.
* - Sets \c PICO_CYW43_ARCH_FREERTOS=1 to select the NO_SYS=0 lwip/FreeRTOS integration
* - Sets \c LWIP_PROVIDE_ERRNO=1 to provide error numbers needed for compilation without an OS
* - Adds the \c pico_lwip as a dependency to pull in lwIP.
* - Adds the lwIP/FreeRTOS code from lwip-contrib (in the contrib directory of lwIP)
*
* Calls into the \c cyw43_driver high level API (cyw43.h) may be made from any task or from lwIP callbacks, but not from IRQs. Calls into the lwIP RAW API (which is not thread safe)
* must be bracketed with \ref cyw43_arch_lwip_begin and \ref cyw43_arch_lwip_end. It is fine to bracket calls made from within lwIP callbacks too; you just don't have to.
*
* \note this wrapper library requires you to link FreeRTOS functionality with your application yourself.
*
* * \b pico_cyw43_arch_none - If you do not need the TCP/IP stack but wish to use the on-board LED.
*
* This wrapper library:
* - Sets \c CYW43_LWIP=0 to disable lwIP support in \c pico_cyw43_arch and \c cyw43_driver
