cleanup: factor out dataSendToSlaveStopEval
The global dataSendToSlaveStopEval was set all over the place, but never
tested, so useless to set it. And remove an unused piece of code. Trivial
cleanup.

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. [..] use global variable frameCounter[] in gfxengine.c to control memory all but the last three are identical to caller_id for example 0x05 are the menu frames the last but one is a sum for higher numbers (shouldn't be any) the last but one are those in status RELEASED the last are those CLEAR (as of 151202 down to 4 in logbook mode) [..] 4 pages are used for two double memories for screenshots (since Nov. 15) ============================================================================== ##### 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 ============================================================================== ##### settings ##### ============================================================================== [..] files: settings.c, settings.h 1. adjust struct SSettings in settings.h 2. adjust const SSettings SettingsStandard in settings.c 3. adjust set_new_settings_missing_in_ext_flash() 4. adjust check_and_correct_settings() IMPORTANT as it changes values! ============================================================================== ##### specials ##### ============================================================================== [..] There was code for vector graphics from great demos (peridiummmm and jupiter) that can be fitted again ============================================================================== ##### ppO2 sensors ##### ============================================================================== [..] in tCCR.c is function get_ppO2SensorWeightedResult_cbar();
