用 Embassy 开发 Xinput 协议手柄

Project repository: GitHub repo

Road Map¶

• proof of concept
  • implement xinput on stm32f103
  • implement keypad scan on stm32f103
    • now use existing keypad from crates.io
  • act like a gamepad
• implement keymap on stm32f103
• port to nrf52840
• implement ble (different modes)
  • hid keyboard & mouse
  • gamepad
• improve overall structure
• implement mode switch
• board abstraction
• package/lib?
• custom board (prototype)
  • NFC
  • battery
  • rumble
  • LED
• and custom shell
• production design

Important thing:

• what about the marketing?

about bluetooth¶

https://en.wikipedia.org/wiki/Xbox_Wireless_Controller#Summary

• Classic Bluetooth HID profile
• HID over GATT Profile

I wonder if they are mostly the same protocol on a higher level, because there are evidences showing the existence of Bluetooth LE XInput compatible controller.
