I am trying to decode this signal coming from a control board for car ultrasound sensors. The first part of the signal seems to be a kind of sync frame. In the second part, instead, I should find the sensor id and the detected distance. The third part should be a reset.
I think it's encoded in PWM or Manchester encoding. Can anybody give me some more information?
UPDATE N.1: Opening the case, i found this board: It is driven by this microcontroller: UPD78F9222MC(T)-5A4-A - Microcontrollore 8 Bit, 78K0S/Kx, 10 MHz, 4 KB, 256 Byte, 20 Pin, SSOP. So trasmission should be UART or LIN (but i think that is UART).
I expect as payload some bits (min. 3) that can identify one of eight's sensor, and a float that rappresent distance.
