블루투스 조이스틱 DIY

음.. 근데 이거는 하나도.. 두개로 나눠진걸 합쳐서 보낼수도 있으려나?

큭.. 19.95$

좋은 제품이긴 한데 내가 상상한 걸 만들기에는 조금 많이 부족한 듯?

단순하게 On/Off만 되는 12개 짜리 조이스틱 보드인듯

Control and LEDs To the right of the power pins, there are some control pins RS - this is the reset pin. To reset the module, pull this pin to ground. It does not affect pairing. L2 - this is the same output that is connected to the PairLED. If you want to put this in a box and have an external Pair indicator LED, wire an LED from this pin, through a 1K resistor, to ground. PB - this is the pair button pin. It is connected to the button onboard that is used to reset the pairing. If you want to make another, external pair button, connect a switch from this key to 3V (not ground!) L1 - this is the same output that is connected to the KeyLED. If you want to put this in a box and have an external Key-press indicator LED, wire an LED from this pin, through a 1K resistor, to ground. RX - this is the UART input, used if you want to send UART->Keypress data, or re-map the buttons. It is 5V compliant, use 3V-5V TTL logic, 9600 baud. TX - this is the UART output, used for watching debug data or re-mapping the buttons. It is 3V logic level output.

HC-05 인지 RN-42인지 잘 모르겠네.. 아무튼 이렇게 설정하면 HID JOYPAD로 인식을 하나보다 ㄷㄷ

그냥.. BT HID로 설정하고

6바이트 날리면 되는건가?

RN-42

정확하게는 RN-42로는 안되고(SPP만 지원) RN42HID나 RN42NHID로 된 녀석이 필요하다.

대충 찾아 보는데.. RN42HID로 된 녀석들이 잘 안보이는지라.. 잘못샀다가는 돈만 날릴 듯?

모델명은 같은데 HID 여부가 다르니 주의 

30000원 / 정찰가 인듯?
