/**
Hyundai TPMS (VDO) FSK 10 byte Manchester encoded CRC-8 TPMS data.
Tested on a Hyundai i30 PDE. It uses sensors from Continental/VDO. VDO reference/part no.: A2C98607702, generation TG1C, FCC ID: KR5TIS-01
Similar sensors and probably protocol are used in models from BMW, Fiat-Chrysler-Alfa, Peugeot-Citroen, Hyundai-KIA, Mitsubishi, Mazda, etc.
https://www.vdo.com/media/746526/2019-10_tpms-oe-sensors_application-list.pdf
Hence my compilation and fine-tuning the already present as of late 2020 source for Citroen, Abarth and Jansite.
Working Temperature: -50°C to 125°C (but according to some sources the chip can only handle -40°C)
Working Frequency: 433.92MHz+-38KHz
Tire monitoring range value: 0kPa-350kPa+-7kPa
- Working Temperature: -50°C to 125°C (but according to some sources the chip can only handle -40°C)
- Working Frequency: 433.92MHz+-38KHz
- Tire monitoring range value: 0kPa-350kPa+-7kPa
Packet nibbles:
PRE UU IIIIIIII FR PP TT BB CC
PRE UU IIIIIIII FR PP TT BB CC
- PRE = preamble is 55 55 55 56 (inverted: aa aa aa a9)
- U = state, decoding unknown. In all tests has values 20,21,22,23 in hex.
Probably codes the information how was the sensor activated - external service tool or internal accelometer (first byte) and the speed of transmission?

- I = sensor Id in hex
- F = Flags, in my tests always 0. Most probably here are coded in separate bits the alert flags for low pressure (below 150kPa), temperature and low battery.
So it should be something like 00 (0) - all ok, 01 (1) - low pressure, 11 (3) - low pressure and low battery and so on, but more testing is necessary

- R = packet Repetition in every burst (about 10-11 identical packets are transmitted in every burst approximately once per 64 seconds)
- P = Pressure X/5=PSI or X(dec).1.375=kPa
- T = Temperature (deg C offset by 50)
