	==============================================================================
							##### bootloader specific #####
	==============================================================================

	151130	hw	sleep on button3
								(MX_tell_reset_logik_alles_ok() + DataEX_call() in endlos loop)

	==============================================================================
							##### bootloader specific #####
	==============================================================================

	Bootloader info is set right here in this file.
	The location is 0x0800A000 instead of 0x08050000 (firmware)

	on system reset (Menu Start Bootloader in firmware) the update process
	is started automatically if no button is pressed

	if the right button is pressed the bootloader menu is started

	after update process (with update or empty) cleaning of EEPROM is started
	afterwards the watchdog reset starts without activating the update process

	bluetooth chip is started in tComm on start of the mini bootloader firmware

	SMALLCPU_CSB_PIN must be re-set to 0 to communicate with small CPU / CPU2 / RTE

	for RealTerm to send file / firmware, Delays has to be increased to 0

	RTE update / SPI1 with DMA gave IBUSERR, now it is working fine :-) 150828
	==============================================================================
	from standard firmware, parts might be invalid here:
	==============================================================================
							##### IRQs #####
	==============================================================================
	[..] The IRQs are very important and most functions should only run there.

				PreemptPriority are as follows
				(#) 2 (low)		sprintf _only_ here. Don't use in maintask or anywhere else.
											Called by Buttons und Timer3
											Timer3 is 1/10 second
				(#) 1 (mid)		anything that should work while in IRQ2 like HalDelay(), VSYNC
											and DMA2D Transfer Complete for housekeepingFrame();
				(#)	0 (high)	_very very short_ interrupts like The HAL hardware part for
											spi, uart, i2c.

				SubPriority within 	PreemptPriority give the order to execute.
				Introduced 30.Oct.14 as it used by several HAL examples.
				Three levelAmbients are available (2 low,1 mid,0 high)

				The STM32F4 has 4bits for IRQ levelAmbients, divided 2/2 in this code
				with the NVIC_PRIORITYGROUP_2 setting.

	==============================================================================
							##### MainTask #####
	==============================================================================
	[..] For everthing slow without importance to be 'in time'.
			 Like VPM and Buehlmann.
			 No sprintf and probably no GFX_SetFramesTopBottom() stuff neither.
			 If sprintf is called while sprintf is executed it blows up everything.

	==============================================================================
							##### Frames / the external SDRAM #####
	==============================================================================
	[..] The SDRAM is handled by getFrame() and releaseFrame().
			 Each frame with 800*480*2 Bytes.
			 Be carefull to release every frame
			 otherwise there will be a memory leakage over time.
			 housekeepingFrame() in the MainTask takes care of cleaning the frames.
			 All frames are filled with 0x00. This will be transparent with color of
			 CLUT_Font020 (is CLUT 0) if the alpha is set for a 16bit pair.
			 housekeepingFrame() delays the cleaning of frames still used as screen
			 buffer to prevent flickering.

	==============================================================================
							##### Display #####
	==============================================================================
	[..] There is a Top layer, Bottom layer and background color.
			 All are perfectly alpha-blended by hardware.

				(#) top layer			has 800x480 option function calls only
													as it is not used for cursors here
				(#)	bottom layer	has free size and start option to be used
													for cursors (or sprites in the future ;-)
				(#) background		only black in the moment.
													ToDo: Could be anything else for warnings etc.
													if needed

	[..] Frame updates, switching and cursors is done with

				(#) GFX_SetFramesTopBottom() and the subset
						GFX_SetFrameTop() + GFX_SetFrameBottom()
						Those do not change anything on the display but give commands to..
				(#) GFX_change_LTDC()	The only place that changes the pointer.
															This prevents erratic behaviour if several changes
															are made within one refresh rate of the screen.
															Is called in IRQ by PD4 and HAL_GPIO_EXTI_IRQHandler
															from VSYNC signal.

	[..] Content

				(#) Colors	by LookupTable only. This could be modified by
										system settings in the future. (gfx_color.h/.c)

				(#) Text		by text_multilinguage.h/.c with one char
										necessary only starting from '\x80'
										with automatic language switch by
										selected_language in SSettings
										see openEdit_Language() in tMenuEditSystem.c
										Therefore there are differnent functions
										for example:
										write_label_fix() for single char multilanguage
										write_label_var() for strings that could include
										multilanguage as well
										see GFX_write_string() to get an overview of the controls
										as well as the command list in gfx_engine.h
										There is no clear before writing, text overlay is always on.
										Many options to have LargeFont.SmallFont for numbers etc.

	==============================================================================
							##### Update, DualBoot and build-in FLASH memory usage #####
	==============================================================================
	[..] Boot0 pin, Boot1/PB2 pin and BFB2 software bit control the behaviour.
				PB2 should be tied to GND.
				Boot0 == VDD -> bootloader on start, otherwise boot from Bank1 or Bank2
				depending on BFB2.
				Bank2 contains the Fonts and should contain a proper test code in future
				Bank1 is the main code (Bank1 is 1 MB too, usage as of Oct. 14 is 200 KB)
	[..] Bootloader should be either UART or USB (on FS pins _only_)
				USB HS to FS like on the Eval board does not work.
	[..] Bootloader for the smaller CPU2 is implemented via the SPI used for DMA copy.

	==============================================================================
							##### Connection to CPU2 (STM32F411 as of Oct.14 #####
	==============================================================================
	[..] Connected via SPI and DMA for every purpose.
				two entire arrays are transfered for data security reasons
				with respect to master (STM32F429) might interrupt internal
				data copy in CPU2 (like hi byte, low byte, etc.).
	[..] The entire life data is calculated in CPU2. Like tissues, CNS,...
				Therefore the main unit is _not_ necessarily a Real Time system.
				Simulation on the main unit can be executed without disrupting life data.
	[..] SPI is triggered and timed by calling DataEX_call() in data_exchange_main.c
				DataEX_copy_to_LifeData() does the transfer from buffer to variables used.

	==============================================================================
							##### Menu, MenuEdit, Info #####
	==============================================================================
	[..] tMenu.c, tMenuEdit.c and tInfo.c is the system used.
				logbook is part of Info not Menu.
				The Info Menu is accessed by button 'Back'
				The regular Menu is accessed by button 'Enter'
	[..] Menu content is kept in frame memory for fast access.
				There is no need to build pages if the 'Enter' button is pressed.
				This is in contrast to MenuEdit pages.
	[..] Button control for new pages (and pages in general) have to implemented
				in tMenu.c, tMenuEdit.c or tInfo.c

	[..] ToDo (Oct. 14) Timeout for menus via Timer3 / IRQ 2

	==============================================================================
							##### specials #####
	==============================================================================
	[..] There was code for vector graphics from great demos
				(peridiummmm and jupiter) that can be fitted again
