-  ==============================================================================
-              ##### bootloader specific #####
-  ==============================================================================
-
-	151130	chsw	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

+	==============================================================================
+							##### bootloader specific #####
+	==============================================================================
+
+	151130	chsw	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
