36
+ − 41 151130 hw sleep on button3
960
+ − 42 (MX_tell_reset_logik_alles_ok() + DataEX_call() in endless loop)
30
+ − 43
+ − 44 ==============================================================================
+ − 45 ##### bootloader specific #####
+ − 46 ==============================================================================
+ − 47
+ − 48 Bootloader info is set right here in this file.
+ − 49 The location is 0x0800A000 instead of 0x08050000 (firmware)
+ − 50
+ − 51 on system reset (Menu Start Bootloader in firmware) the update process
+ − 52 is started automatically if no button is pressed
+ − 53
+ − 54 if the right button is pressed the bootloader menu is started
+ − 55
+ − 56 after update process (with update or empty) cleaning of EEPROM is started
+ − 57 afterwards the watchdog reset starts without activating the update process
+ − 58
+ − 59 bluetooth chip is started in tComm on start of the mini bootloader firmware
+ − 60
+ − 61 SMALLCPU_CSB_PIN must be re-set to 0 to communicate with small CPU / CPU2 / RTE
+ − 62
+ − 63 for RealTerm to send file / firmware, Delays has to be increased to 0
+ − 64
+ − 65 RTE update / SPI1 with DMA gave IBUSERR, now it is working fine :-) 150828
+ − 66 ==============================================================================
+ − 67 from standard firmware, parts might be invalid here:
+ − 68 ==============================================================================
+ − 69 ##### IRQs #####
+ − 70 ==============================================================================
+ − 71 [..] The IRQs are very important and most functions should only run there.
+ − 72
+ − 73 PreemptPriority are as follows
+ − 74 (#) 2 (low) sprintf _only_ here. Don't use in maintask or anywhere else.
+ − 75 Called by Buttons und Timer3
+ − 76 Timer3 is 1/10 second
+ − 77 (#) 1 (mid) anything that should work while in IRQ2 like HalDelay(), VSYNC
+ − 78 and DMA2D Transfer Complete for housekeepingFrame();
+ − 79 (#) 0 (high) _very very short_ interrupts like The HAL hardware part for
+ − 80 spi, uart, i2c.
+ − 81
+ − 82 SubPriority within PreemptPriority give the order to execute.
+ − 83 Introduced 30.Oct.14 as it used by several HAL examples.
+ − 84 Three levelAmbients are available (2 low,1 mid,0 high)
+ − 85
+ − 86 The STM32F4 has 4bits for IRQ levelAmbients, divided 2/2 in this code
+ − 87 with the NVIC_PRIORITYGROUP_2 setting.
+ − 88
+ − 89 ==============================================================================
+ − 90 ##### MainTask #####
+ − 91 ==============================================================================
960
+ − 92 [..] For everything slow without importance to be 'in time'.
30
+ − 93 Like VPM and Buehlmann.
+ − 94 No sprintf and probably no GFX_SetFramesTopBottom() stuff neither.
+ − 95 If sprintf is called while sprintf is executed it blows up everything.
+ − 96
+ − 97 ==============================================================================
+ − 98 ##### Frames / the external SDRAM #####
+ − 99 ==============================================================================
+ − 100 [..] The SDRAM is handled by getFrame() and releaseFrame().
+ − 101 Each frame with 800*480*2 Bytes.
960
+ − 102 Be careful to release every frame
30
+ − 103 otherwise there will be a memory leakage over time.
+ − 104 housekeepingFrame() in the MainTask takes care of cleaning the frames.
+ − 105 All frames are filled with 0x00. This will be transparent with color of
+ − 106 CLUT_Font020 (is CLUT 0) if the alpha is set for a 16bit pair.
+ − 107 housekeepingFrame() delays the cleaning of frames still used as screen
+ − 108 buffer to prevent flickering.
+ − 109
+ − 110 ==============================================================================
+ − 111 ##### Display #####
+ − 112 ==============================================================================
+ − 113 [..] There is a Top layer, Bottom layer and background color.
+ − 114 All are perfectly alpha-blended by hardware.
+ − 115
+ − 116 (#) top layer has 800x480 option function calls only
+ − 117 as it is not used for cursors here
+ − 118 (#) bottom layer has free size and start option to be used
+ − 119 for cursors (or sprites in the future ;-)
+ − 120 (#) background only black in the moment.
+ − 121 ToDo: Could be anything else for warnings etc.
+ − 122 if needed
+ − 123
+ − 124 [..] Frame updates, switching and cursors is done with
+ − 125
+ − 126 (#) GFX_SetFramesTopBottom() and the subset
+ − 127 GFX_SetFrameTop() + GFX_SetFrameBottom()
+ − 128 Those do not change anything on the display but give commands to..
+ − 129 (#) GFX_change_LTDC() The only place that changes the pointer.
960
+ − 130 This prevents erratic behavior if several changes
30
+ − 131 are made within one refresh rate of the screen.
+ − 132 Is called in IRQ by PD4 and HAL_GPIO_EXTI_IRQHandler
+ − 133 from VSYNC signal.
+ − 134
+ − 135 [..] Content
+ − 136
+ − 137 (#) Colors by LookupTable only. This could be modified by
+ − 138 system settings in the future. (gfx_color.h/.c)
+ − 139
+ − 140 (#) Text by text_multilinguage.h/.c with one char
+ − 141 necessary only starting from '\x80'
+ − 142 with automatic language switch by
+ − 143 selected_language in SSettings
+ − 144 see openEdit_Language() in tMenuEditSystem.c
960
+ − 145 Therefore there are different functions
30
+ − 146 for example:
+ − 147 write_label_fix() for single char multilanguage
+ − 148 write_label_var() for strings that could include
+ − 149 multilanguage as well
+ − 150 see GFX_write_string() to get an overview of the controls
+ − 151 as well as the command list in gfx_engine.h
+ − 152 There is no clear before writing, text overlay is always on.
+ − 153 Many options to have LargeFont.SmallFont for numbers etc.
+ − 154
+ − 155 ==============================================================================
+ − 156 ##### Update, DualBoot and build-in FLASH memory usage #####
+ − 157 ==============================================================================
+ − 158 [..] Boot0 pin, Boot1/PB2 pin and BFB2 software bit control the behaviour.
+ − 159 PB2 should be tied to GND.
+ − 160 Boot0 == VDD -> bootloader on start, otherwise boot from Bank1 or Bank2
+ − 161 depending on BFB2.
+ − 162 Bank2 contains the Fonts and should contain a proper test code in future
+ − 163 Bank1 is the main code (Bank1 is 1 MB too, usage as of Oct. 14 is 200 KB)
+ − 164 [..] Bootloader should be either UART or USB (on FS pins _only_)
+ − 165 USB HS to FS like on the Eval board does not work.
+ − 166 [..] Bootloader for the smaller CPU2 is implemented via the SPI used for DMA copy.
+ − 167
+ − 168 ==============================================================================
+ − 169 ##### Connection to CPU2 (STM32F411 as of Oct.14 #####
+ − 170 ==============================================================================
+ − 171 [..] Connected via SPI and DMA for every purpose.
+ − 172 two entire arrays are transfered for data security reasons
+ − 173 with respect to master (STM32F429) might interrupt internal
+ − 174 data copy in CPU2 (like hi byte, low byte, etc.).
+ − 175 [..] The entire life data is calculated in CPU2. Like tissues, CNS,...
+ − 176 Therefore the main unit is _not_ necessarily a Real Time system.
+ − 177 Simulation on the main unit can be executed without disrupting life data.
+ − 178 [..] SPI is triggered and timed by calling DataEX_call() in data_exchange_main.c
+ − 179 DataEX_copy_to_LifeData() does the transfer from buffer to variables used.
+ − 180
+ − 181 ==============================================================================
+ − 182 ##### Menu, MenuEdit, Info #####
+ − 183 ==============================================================================
+ − 184 [..] tMenu.c, tMenuEdit.c and tInfo.c is the system used.
+ − 185 logbook is part of Info not Menu.
+ − 186 The Info Menu is accessed by button 'Back'
+ − 187 The regular Menu is accessed by button 'Enter'
+ − 188 [..] Menu content is kept in frame memory for fast access.
+ − 189 There is no need to build pages if the 'Enter' button is pressed.
+ − 190 This is in contrast to MenuEdit pages.
+ − 191 [..] Button control for new pages (and pages in general) have to implemented
+ − 192 in tMenu.c, tMenuEdit.c or tInfo.c
+ − 193
+ − 194 [..] ToDo (Oct. 14) Timeout for menus via Timer3 / IRQ 2
+ − 195
+ − 196 ==============================================================================
+ − 197 ##### specials #####
+ − 198 ==============================================================================
+ − 199 [..] There was code for vector graphics from great demos
+ − 200 (peridiummmm and jupiter) that can be fitted again
