I want to make the same signal like the following images using an Arduino Uno. But I can't find the baudrate of this signal.
I calculated baudrate the same way as Wikipedia. But when I used the baudrate I got framing error.
The duration of the start bit: 0.2223 ms
1/ ( 0.2233 / 1000) = 4478 bit/s
What did I do wrong?
Update
The device has the following 4 pins.
- VIN: 12 V
- GND
- GND
- SIGNAL: 3.3 V
I don't have any documents like a datasheet or a manual. I think that it uses UART communication because there is only one signal pin.
I upload the logicdata file on my Dropbox account: Here!
