Usage
- Pairing: press SW button for 2s, indicator led turns on to enter into pairing mode; release the button, indicator led turns off. Press one of the buttons on RF remote(one button every time), indicator led flashes 4 times every 300ms, which means paired successfully, saved value of the button and exited pairing mode.
- Output: press a successfully paired button to receive valid data, indicator led will be on for 200ms, data port (corresponding one in D0~D3) will be leveled up for 200ms.
- Clear: press SW for 8s, indicator led will be on at 2s and off at 8s. All pairing codes will be cleared, all buttons will be invalid.
