WebHID keyboard programmer replacing Windows-only official tool with cross-platform browser access.

Strengths

•WebHID API enables cross-platform keyboard programming without Windows-only official software.
•Multiple profile storage allows switching layouts without reflashing keyboard firmware each time.

Weaknesses

•Chrome-only browser support excludes Firefox and Safari users from WebHID functionality.
•No mobile browser support limits on-the-go keyboard configuration and adjustments.

Post Description

I have a ch57x based keyboard/macropad, and hate (unsurprisingly) the (windows only) programming tool that it comes with.

Given that I can use a web based tool for my wooting keyboard, I figured the same must be true for the ch57x, I couldn't find one, so I wrote one.

Capabilities:

Reading and writing configurations to a ch57x keyboard Storing multiple profiles for switching layouts Key sequences, media keys, and mouse events

Works on MacOS and Windows (and presumably Linux, but not tested yet)

Current limitations:

Chrome/Chromium, Edge, and Opera only. I haven't tested Chromium or Opera so ymmv No mobile browser that I'm aware of supports WebHID Firefox and Safari will likely never support programming HID devices
