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();
