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 Repo is https://github.com/pollrobots/ch57x-programmer
