+ − 29 ==============================================================================
+ − 30 ##### Firmware Info #####
+ − 31 ==============================================================================
+ − 32 [..] In settings.c including text and magic stuff
+ − 33 ==============================================================================
+ − 34 ##### IRQs #####
+ − 35 ==============================================================================
+ − 36 [..] The IRQs are very important and most functions should only run there.
+ − 37
+ − 38 PreemptPriority are as follows
+ − 39 (#) 2 (low) sprintf _only_ here. Don't use in maintask or anywhere else.
+ − 40 Called by Buttons und Timer3
+ − 41 Timer3 is 1/10 second
+ − 42 (#) 1 (mid) anything that should work while in IRQ2 like HalDelay(), VSYNC
+ − 43 and DMA2D Transfer Complete for housekeepingFrame();
+ − 44 (#) 0 (high) _very very short_ interrupts like The HAL hardware part for
+ − 45 spi, uart, i2c.
+ − 46
+ − 47 SubPriority within PreemptPriority give the order to execute.
+ − 48 Introduced 30.Oct.14 as it used by several HAL examples.
+ − 49 Three levelAmbients are available (2 low,1 mid,0 high)
+ − 50
+ − 51 The STM32F4 has 4bits for IRQ levelAmbients, divided 2/2 in this code
+ − 52 with the NVIC_PRIORITYGROUP_2 setting.
+ − 53
+ − 54 ==============================================================================
+ − 55 ##### MainTask #####
+ − 56 ==============================================================================
+ − 57 [..] For everthing slow without importance to be 'in time'.
+ − 58 Like VPM and Buehlmann.
+ − 59 No sprintf and probably no GFX_SetFramesTopBottom() stuff neither.
+ − 60 If sprintf is called while sprintf is executed it blows up everything.
+ − 61
+ − 62 ==============================================================================
+ − 63 ##### Frames / the external SDRAM #####
+ − 64 ==============================================================================
+ − 65 [..] The SDRAM is handled by getFrame() and releaseFrame().
+ − 66 Each frame with 800*480*2 Bytes.
+ − 67 Be carefull to release every frame
+ − 68 otherwise there will be a memory leakage over time.
+ − 69 housekeepingFrame() in the MainTask takes care of cleaning the frames.
+ − 70 All frames are filled with 0x00. This will be transparent with color of
+ − 71 CLUT_Font020 (is CLUT 0) if the alpha is set for a 16bit pair.
+ − 72 housekeepingFrame() delays the cleaning of frames still used as screen
+ − 73 buffer to prevent flickering.
+ − 74
+ − 75 [..] use global variable frameCounter[] in gfxengine.c to control memory
+ − 76 all but the last three are identical to caller_id
+ − 77 for example 0x05 are the menu frames
+ − 78 the last but one is a sum for higher numbers (shouldn't be any)
+ − 79 the last but one are those in status RELEASED
+ − 80 the last are those CLEAR (as of 151202 down to 4 in logbook mode)
+ − 81
+ − 82 [..] 4 pages are used for two double memories for screenshots (since Nov. 15)
+ − 83
+ − 84 ==============================================================================
+ − 85 ##### Display #####
+ − 86 ==============================================================================
+ − 87 [..] There is a Top layer, Bottom layer and background color.
+ − 88 All are perfectly alpha-blended by hardware.
+ − 89
+ − 90 (#) top layer has 800x480 option function calls only
+ − 91 as it is not used for cursors here
+ − 92 (#) bottom layer has free size and start option to be used
+ − 93 for cursors (or sprites in the future ;-)
+ − 94 (#) background only black in the moment.
+ − 95 ToDo: Could be anything else for warnings etc.
+ − 96 if needed
+ − 97
+ − 98 [..] Frame updates, switching and cursors is done with
+ − 99
+ − 100 (#) GFX_SetFramesTopBottom() and the subset
+ − 101 GFX_SetFrameTop() + GFX_SetFrameBottom()
+ − 102 Those do not change anything on the display but give commands to..
+ − 103 (#) GFX_change_LTDC() The only place that changes the pointer.
+ − 104 This prevents erratic behaviour if several changes
+ − 105 are made within one refresh rate of the screen.
+ − 106 Is called in IRQ by PD4 and HAL_GPIO_EXTI_IRQHandler
+ − 107 from VSYNC signal.
+ − 108
+ − 109 [..] Content
+ − 110
+ − 111 (#) Colors by LookupTable only. This could be modified by
+ − 112 system settings in the future. (gfx_color.h/.c)
+ − 113
+ − 114 (#) Text by text_multilinguage.h/.c with one char
+ − 115 necessary only starting from '\x80'
+ − 116 with automatic language switch by
+ − 117 selected_language in SSettings
+ − 118 see openEdit_Language() in tMenuEditSystem.c
+ − 119 Therefore there are differnent functions
+ − 120 for example:
+ − 121 write_label_fix() for single char multilanguage
+ − 122 write_label_var() for strings that could include
+ − 123 multilanguage as well
+ − 124 see GFX_write_string() to get an overview of the controls
+ − 125 as well as the command list in gfx_engine.h
+ − 126 There is no clear before writing, text overlay is always on.
+ − 127 Many options to have LargeFont.SmallFont for numbers etc.
+ − 128
+ − 129 ==============================================================================
+ − 130 ##### Update, DualBoot and build-in FLASH memory usage #####
+ − 131 ==============================================================================
+ − 132 [..] Boot0 pin, Boot1/PB2 pin and BFB2 software bit control the behaviour.
+ − 133 PB2 should be tied to GND.
+ − 134 Boot0 == VDD -> bootloader on start, otherwise boot from Bank1 or Bank2
+ − 135 depending on BFB2.
+ − 136 Bank2 contains the Fonts and should contain a proper test code in future
+ − 137 Bank1 is the main code (Bank1 is 1 MB too, usage as of Oct. 14 is 200 KB)
+ − 138 [..] Bootloader should be either UART or USB (on FS pins _only_)
+ − 139 USB HS to FS like on the Eval board does not work.
+ − 140 [..] Bootloader for the smaller CPU2 is implemented via the SPI used for DMA copy.
+ − 141
+ − 142 ==============================================================================
+ − 143 ##### Connection to CPU2 (STM32F411 as of Oct.14 #####
+ − 144 ==============================================================================
+ − 145 [..] Connected via SPI and DMA for every purpose.
+ − 146 two entire arrays are transfered for data security reasons
+ − 147 with respect to master (STM32F429) might interrupt internal
+ − 148 data copy in CPU2 (like hi byte, low byte, etc.).
+ − 149 [..] The entire life data is calculated in CPU2. Like tissues, CNS,...
+ − 150 Therefore the main unit is _not_ necessarily a Real Time system.
+ − 151 Simulation on the main unit can be executed without disrupting life data.
+ − 152 [..] SPI is triggered and timed by calling DataEX_call() in data_exchange_main.c
+ − 153 DataEX_copy_to_LifeData() does the transfer from buffer to variables used.
+ − 154
+ − 155 ==============================================================================
+ − 156 ##### Menu, MenuEdit, Info #####
+ − 157 ==============================================================================
+ − 158 [..] tMenu.c, tMenuEdit.c and tInfo.c is the system used.
+ − 159 logbook is part of Info not Menu.
+ − 160 The Info Menu is accessed by button 'Back'
+ − 161 The regular Menu is accessed by button 'Enter'
+ − 162 [..] Menu content is kept in frame memory for fast access.
+ − 163 There is no need to build pages if the 'Enter' button is pressed.
+ − 164 This is in contrast to MenuEdit pages.
+ − 165 [..] Button control for new pages (and pages in general) have to implemented
+ − 166 in tMenu.c, tMenuEdit.c or tInfo.c
+ − 167
+ − 168 [..] ToDo (Oct. 14) Timeout for menus via Timer3 / IRQ 2
+ − 169
+ − 170 ==============================================================================
+ − 171 ##### settings #####
+ − 172 ==============================================================================
+ − 173 [..] files: settings.c, settings.h
+ − 174 1. adjust struct SSettings in settings.h
+ − 175 2. adjust const SSettings SettingsStandard in settings.c
+ − 176 3. adjust set_new_settings_missing_in_ext_flash()
+ − 177 4. adjust check_and_correct_settings() IMPORTANT as it changes values!
+ − 178
+ − 179 ==============================================================================
+ − 180 ##### specials #####
+ − 181 ==============================================================================
+ − 182 [..] There was code for vector graphics from great demos
+ − 183 (peridiummmm and jupiter) that can be fitted again
+ − 184
+ − 185 ==============================================================================
+ − 186 ##### ppO2 sensors #####
+ − 187 ==============================================================================
+ − 188 [..] in tCCR.c is function get_ppO2SensorWeightedResult_cbar();
