UKUS_Toyota_TPMS_Monitor_V11_8

Arduino
//Changes:
//V1.0 - Originally published version
//V2.0 - Altered to allow support for spare tyre reporting (although not displayed on LCD display)
//V3.0 - Added #define in globals.h to switch between BAR and PSI
//V4.0 - Now uses synchronous data from CC1101 and option of using either the SPI or the hardware pin for the CD signal (#define USE_HW_CD in globals.h). Also tideied up debug information if required (globals.h #defines)
//V5.0 - Corrected possible sync error when looking for start of data stream. Fix should improve hit rate on valid TPMS detection
//V5.1 - Added freq offset updates (SWRA159) - removed again(makes it worse!)
//V5.1.1 - Added functions for extracting RSSI as dbm
//V6.0 - Added code for options for US (315MHz) or UK (433MHz), also for different sensor types (PMV-C210, PMV-107J)
//V6.1 - Added support for Seeeduino Xiao
//V6.2 - Included support for Renault (Renault Clio, Renault Captur and maybe Dacia Sandero?) as an option (to be verified)
//V6.3 - Included support for Citroen (possibly also includes Peugeot and likely Fiat, Mitsubishi, VDO-types) as an option (to be verified)
//V6.4 - Some code rationalisation, all sensor timings now in Configs.h
//V6.5 - Tried to improve PMV-107J decode by starting at the end of the buffer and working forwards
//V6.6 - Added other car types (under development), changed PMV-107J frequency deviation, added #define as option to only detect specified IDs, stripped leading 4 bits from ID (as per 'Glopes' comment) for Toyota, moved some globals settings to Config.h, changed AGC settings 
//V6.7 - Adjusted PMV_C210 presure calculation to lower PSI by 0.3 (as suggested by Steven Andrews by comparing with Autel programmer). 
//     - Added option for displaying Fahrenheit (#ifdef DISPLAY_TEMP_AS_FAHRENHEIT in configs.h) rather than centigrade.
//     - Re-introduced flashing display if pressures outside of pre-set limits (enabled by #define ENABLE_PRESSURE_ALARMS in configs.h. PressureLowLimits and PressureHighLimits in config.h should be set as required)
//V7.0 - Included option for 1.8" TFT display (requires Seeeduino Xiao for extra memory)
//V8.0 - Added optional audible alarm for pressure alarms. Improved display flashing. Tested with Nissan Leaf 433MHz OK
//V9.0 - Added Pontiac (US) decoder option, moved all CC1101 configs to sensor-spcific include files, improved timer handling. Added temperature compensation for pressure limits (set pressure limits reference temperature in configs.h). Added kPA pressure display option.
//       Pressures always stored locally as psi and temperatures as deg C - including limits (converted if required for the display).
//       Tyre pressure and temperature limits are assumed to be in the required units e.g. bar, kpa, psi, degC, degF depending on config choice.
//       Added support for 240x240 round display (Steven Andrews' display code)
//V9.1 - Added provisional support for Arduino Nano 33 IOT board
//V9.2 - Fixed bugs in audible alarm for temperatures.. Fixed missing F/C for round display.
//V9.3 - Corrected some title positioning for display.h, Added support for Renault Zoe (pre 07/2019)
//V9.4 - Corrected compile error when not using display - thanks Zaran on Hackster.io
//V9.5 - Changes to cope with multiple tyre sets (Summer/Winter). Corrected bug in ID matching (IDs were allocated to PROGMEM but referenced as SRAM for lookups), this meant tyre position was not being reported correctly. Moved Ref[3] to globals.
//V9.6 - Fixed bug where lcd display was partially obliterated if TYRECOUNT > 4 (the default is now 5)
//V9.7 - Fixed bug in Ford.h which caused out of range temperture values to be displayed on screen when temperture below 0C. 
//       Changes to support new larger screen type (supplied by Steven Andrews' - thank you!). 2.4inch LCD Display Module 65K RGB Colors, ILI9341 2.4" TFT 240320. Requires Adafruit ILI9341 library.
//V9.8 - Added support for Truck Solar TPMS and Mega256 build
//V9.9 - Added support for Ford strange Ford E-series (Tom Logan). It appears temperature format is reported in 2 ways depending upon whether or not the sensor was manually triggered (or not)
//V10.0 - Improved Ford incoming message handling
//V10.1 - Changed Ford pressure decode in line with actual E-series Schrader sensor feedback. This sensor also seems to delay sending temperatures after sleeping and sends a counter instead.
//V10.2 - Missing conditional for 2.4" screen in setup in .ino file (line 350) preventing initialisation of display (USE_24_INCH_ILI9341_DISPLAY). Causes screen to continually display white.
//V10.3 - Changed PMV-107J & PMV-C210 to try to improve detections. Code now walks through the received bit stream until a valid checksum match is found (or runs out of data)
//        This avoids the need to look for sync bits which may not be reliable at the start of the bit stream (includes change to common.h)
//V10.4 - Added trial for Toyota Sienna (TRW C070 sensor)
//V10.5 - Improvements to Toyota Sienna TRW C070 detection/validation. Added Hyundai I35 as option for this same sensor. 
//        Fixed temperature display bug (thanks Larry on Hackster for pointing this out.) - it would overflow/underflow with certain readings
//        Feedback from Alistair Clark on Hackster indicates that the C210 decode also works for Toyota Corolla (2019-22 PMV-C215 sensor)
//V10.6 - Corrected slight bug in display.h for Hyundai (should have been newline print)/ Thanks to grigata on Hackster for pointing this out.
//        Reported by gamer765 that PMV-107J also works for PMV-C11A sensors.
//        Added support for Hyundai Tucson TL/TLE (2015) using Schrader C1100/C8000 sensor. Many thanks to RM for helping on this one.
//V10.7 - Correct bug in CC1101.h in ReadFIFO function - it was missing the return statement (but worked for Xiao without it???)! Thanks to Nomake Wan for helping out on this one.
//        Added possible support for Xiao RP2040 (TBC)
//        Added support for Schrader A0009054100 senosr used on Smart Fortwo 01/2007-02/2014 (433MHz) - OOK
//V10.8 - Debugged to get Xiao RP2040 working. Same schematic as previous Xiao
//V11.0 - Added Winter tyre pressure limits (optionally). These could be easily be missed and cause an indexing outside of the array if INCLUDE_WINTER_SET enabled.
//        Added suport for Summer/Winter tyres on the displays (previously only available on serial output). Basically, if so configured, the
//        Summer and Winter tyre IDs will be recognised and displayed in their position on the display - user should make sure the other tyre set is out of range!
//V11.1 - Abandonded (not published)
//V11.2 - Changed handling of CD in main routine. Need to configure a valid ENDTIMING_MAX for each sensor type. This is used to exit the CD loop early if a reasonable number of bits have been received and it's been > ENDTIMING_MAX since the last edge (i.e. an ivalid bit timing - probably only valid for Manchester coded data)
//V11.3 - Added processor option for Adafruit 3v itsybitsy
//      - Put in conditionals for the TFT display include files to handle different GPIO formats (e.g. D1 vs just 1) depending on processor selected
//V11.4 - Changes from 10.8 affected CDWidth timings causing some sensors not to be detected. Fixed.
//      - Added software version to serial print out at startup
//V11.5 - Added LCD type to serial print out at startup. Debugged Jansite Solar code. Corrected bug in CRC routines. Changed all general declarations to width-specific types e.g. int to int16_t
//V11.6 - Trial of Subaru Impreza sensors code, both 433MHz and 315MHz (the two frequencies have different protocols)
//V11.7 - Tidied sloppy coding as much as possible in order to remove compiler warnings 
//V11.8 - Corrected bug in Manchester decoding under cetain circumstances when the number of leading 'short' timings before a 'long' timing is an odd number.
//        My thanks to Andrey Oleynik for pointing this out. Affected Toyota PMV_C210 and PMV107J
//        Fixed bug in Toyota_PMV_C210 around line 426,, DecodeBitArray call was missing a parameter and therefore calling the wrong instance. 
//        This caused the search for possible alternative valid checksum somewhere in the sequence to have always failed
//        Adjusted Deviation, data rate, AGC settings for PMV107J (US - 315MHz) as recommended by Andrey Oleynik to improve reception
