 @verbatim
 ==============================================================================
 ##### What about hardware without 8 MHz oscillator #####
 ==============================================================================
 [..] modify OTP Byte 1 at 0x1FFF7800 with ST-Link utility

 ==============================================================================
 ##### Where is the RTE Firmware version #####
 ==============================================================================
 [..] in baseCPU2.c <just here below :->

 ==============================================================================
 ##### What to do with the RTE Firmware version #####
 ==============================================================================
 [..] change the values RTErequiredHigh and RTErequiredLow in settings.c
 to start warning via the firmware if not updated

 ==============================================================================
 ##### What it does #####
 ==============================================================================
 [..] All realtime stuff and all what has to be done during sleep

 [..] RealTimeClock. The entire time and date handling (including divetime)
 [..] Hardware control for pressure sensor, compass, battery monitor
 [..] Calculations of tissue load, critical radius, otu, cns
 [..] Switching off the power of the main CPU after request from it.

 ==============================================================================
 ##### IRQs #####
 ==============================================================================
 [..] The IRQs are are only used for SystemTick and SPI TransferComplete after
 DMA data reception.

 [..] HAL_SPI_TxRxCpltCallback() restarts DMA and will call
 scheduleSpecial_Evaluate_DataSendToSlave() only if it is not blocked
 by I2C.
 If the evaluation is blocked it has to be tested and executed afterwards.
 I2C is executed _without_ the usage of interrupts.

 ==============================================================================
 ##### Main loop #####
 ==============================================================================
 [..] is a combination of the while loop below in main.c and code in scheduler.c
 It is similar to the DR5 code / logic - in contrast to the main CPU
 Switching the state is done via global.mode
 The loops in scheduler all run in the main execution thread without
 any job stacks (like it was in the DR5).

 ==============================================================================
 ##### Real Time Clock #####
 ==============================================================================
  The RTC is a separate part of hardware inside the CPU and is not affected
 by reset. Only power-on reset does change something.
 This is fine but the RTC is vital for the Sleep mode as Wakeuptimer.
 This is the only date/time system in the OSTC. The main CPU is passive.
 Data transfer is done with localtime_rtc_tr and localtime_rtc_dr
 in HAL_RTC format to the main CPU and as HAL_RTC structs the way back for
 setting the actual time and date.
 The RTC unit has 20 Byte of V_bat powered SRAM. It could be used
 for something useful in both CPUs.

 ==============================================================================
 ##### File system  #####
 ==============================================================================
 [..] some files are used for both CPUs, like decom.c/.h, data_central.h, ...


 ==============================================================================
 ##### Unique device ID register (96 bits)  #####
 ==============================================================================
 [..] some files are used for both CPUs, like decom.c/.h, data_central.h, ...


 ==============================================================================
 ##### I2C  #####
 ==============================================================================
 [..] used for pressure, compass, (accelerator) and battery gauge
 main cpu and pic (button) is spi


 ==============================================================================
 ##### Firmware Update Info #####
 ==============================================================================
 V0.85			160531	scheduleCheck_pressure_reached_dive_mode_level() changes
 160606	global.no_fly_time_minutes is at least 24h after the dive
 160613	ambient light fixed
 160720	compass calib to Flash  (8000 writes max. as erase has problems)
 160829	do not reset main CPU on power on!
 V0.91			161018	pressure_calculation_AN520_004_mod_MS5803_30BA__09_2015();
 V0.92+		161020	global.sensorError[MAX_SENSORS]
 fix missing init_pressure(); at powerUp of RTE
 added HAL_StatusTypeDef for many functions in pressure.c
 161024	no_fly_time_minutes Backup FIX
 seconds_since_last_dive now related to RTC clock
 161121	close to surface starts at 1 meter below last known surface pressure
 161121	in surface mode dive mode starts @1 mtr difference if surface 880 hPa instead of 700 hPa before
 V0.97+		170213	added global.dataSendToSlave.diveModeInfo for DIVEMODE_Apnea
 added global.dataSendToSlave.setEndDive
 DIVEMODE_Apnea special in scheduler.c (ticksdiff >= 1000) -> no tissue, cns, otu, no change in noFly Time etc.
 V0.99			170320	new HAL Driver Repository
 V1.01			170509	old HAL Driver Repository
