| 20 ##### bootloader specific ##### | |
| 21 ============================================================================== | |
| 22 | |
| 23 151130 chsw sleep on button3 | |
| 24 (MX_tell_reset_logik_alles_ok() + DataEX_call() in endlos loop) | |
| 25 | |
| 26 ============================================================================== | |
| 27 ##### bootloader specific ##### | |
| 28 ============================================================================== | |
| 29 | |
| 30 Bootloader info is set right here in this file. | |
| 31 The location is 0x0800A000 instead of 0x08050000 (firmware) | |
| 32 | |
| 33 on system reset (Menu Start Bootloader in firmware) the update process | |
| 34 is started automatically if no button is pressed | |
| 35 | |
| 36 if the right button is pressed the bootloader menu is started | |
| 37 | |
| 38 after update process (with update or empty) cleaning of EEPROM is started | |
| 39 afterwards the watchdog reset starts without activating the update process | |
| 40 | |
| 41 bluetooth chip is started in tComm on start of the mini bootloader firmware | |
| 42 | |
| 43 SMALLCPU_CSB_PIN must be re-set to 0 to communicate with small CPU / CPU2 / RTE | |
| 44 | |
| 45 for RealTerm to send file / firmware, Delays has to be increased to 0 | |
| 46 | |
| 47 RTE update / SPI1 with DMA gave IBUSERR, now it is working fine :-) 150828 | |
| 48 ============================================================================== | |
| 49 from standard firmware, parts might be invalid here: | |
| 50 ============================================================================== | |
| 51 ##### IRQs ##### | |
| 52 ============================================================================== | |
| 53 [..] The IRQs are very important and most functions should only run there. | |
| 54 | |
| 55 PreemptPriority are as follows | |
| 56 (#) 2 (low) sprintf _only_ here. Don't use in maintask or anywhere else. | |
| 57 Called by Buttons und Timer3 | |
| 58 Timer3 is 1/10 second | |
| 59 (#) 1 (mid) anything that should work while in IRQ2 like HalDelay(), VSYNC | |
| 60 and DMA2D Transfer Complete for housekeepingFrame(); | |
| 61 (#) 0 (high) _very very short_ interrupts like The HAL hardware part for | |
| 62 spi, uart, i2c. | |
| 63 | |
| 64 SubPriority within PreemptPriority give the order to execute. | |
| 65 Introduced 30.Oct.14 as it used by several HAL examples. | |
| 66 Three levelAmbients are available (2 low,1 mid,0 high) | |
| 67 | |
| 68 The STM32F4 has 4bits for IRQ levelAmbients, divided 2/2 in this code | |
| 69 with the NVIC_PRIORITYGROUP_2 setting. | |
| 70 | |
| 71 ============================================================================== | |
| 72 ##### MainTask ##### | |
| 73 ============================================================================== | |
| 74 [..] For everthing slow without importance to be 'in time'. | |
| 75 Like VPM and Buehlmann. | |
| 76 No sprintf and probably no GFX_SetFramesTopBottom() stuff neither. | |
| 77 If sprintf is called while sprintf is executed it blows up everything. | |
| 78 | |
| 79 ============================================================================== | |
| 80 ##### Frames / the external SDRAM ##### | |
| 81 ============================================================================== | |
| 82 [..] The SDRAM is handled by getFrame() and releaseFrame(). | |
| 83 Each frame with 800*480*2 Bytes. | |
| 84 Be carefull to release every frame | |
| 85 otherwise there will be a memory leakage over time. | |
| 86 housekeepingFrame() in the MainTask takes care of cleaning the frames. | |
| 87 All frames are filled with 0x00. This will be transparent with color of | |
| 88 CLUT_Font020 (is CLUT 0) if the alpha is set for a 16bit pair. | |
| 89 housekeepingFrame() delays the cleaning of frames still used as screen | |
| 90 buffer to prevent flickering. | |
| 91 | |
| 92 ============================================================================== | |
| 93 ##### Display ##### | |
| 94 ============================================================================== | |
| 95 [..] There is a Top layer, Bottom layer and background color. | |
| 96 All are perfectly alpha-blended by hardware. | |
| 97 | |
| 98 (#) top layer has 800x480 option function calls only | |
| 99 as it is not used for cursors here | |
| 100 (#) bottom layer has free size and start option to be used | |
| 101 for cursors (or sprites in the future ;-) | |
| 102 (#) background only black in the moment. | |
| 103 ToDo: Could be anything else for warnings etc. | |
| 104 if needed | |
| 105 | |
| 106 [..] Frame updates, switching and cursors is done with | |
| 107 | |
| 108 (#) GFX_SetFramesTopBottom() and the subset | |
| 109 GFX_SetFrameTop() + GFX_SetFrameBottom() | |
| 110 Those do not change anything on the display but give commands to.. | |
| 111 (#) GFX_change_LTDC() The only place that changes the pointer. | |
| 112 This prevents erratic behaviour if several changes | |
| 113 are made within one refresh rate of the screen. | |
| 114 Is called in IRQ by PD4 and HAL_GPIO_EXTI_IRQHandler | |
| 115 from VSYNC signal. | |
| 116 | |
| 117 [..] Content | |
| 118 | |
| 119 (#) Colors by LookupTable only. This could be modified by | |
| 120 system settings in the future. (gfx_color.h/.c) | |
| 121 | |
| 122 (#) Text by text_multilinguage.h/.c with one char | |
| 123 necessary only starting from '\x80' | |
| 124 with automatic language switch by | |
| 125 selected_language in SSettings | |
| 126 see openEdit_Language() in tMenuEditSystem.c | |
| 127 Therefore there are differnent functions | |
| 128 for example: | |
| 129 write_label_fix() for single char multilanguage | |
| 130 write_label_var() for strings that could include | |
| 131 multilanguage as well | |
| 132 see GFX_write_string() to get an overview of the controls | |
| 133 as well as the command list in gfx_engine.h | |
| 134 There is no clear before writing, text overlay is always on. | |
| 135 Many options to have LargeFont.SmallFont for numbers etc. | |
| 136 | |
| 137 ============================================================================== | |
| 138 ##### Update, DualBoot and build-in FLASH memory usage ##### | |
| 139 ============================================================================== | |
| 140 [..] Boot0 pin, Boot1/PB2 pin and BFB2 software bit control the behaviour. | |
| 141 PB2 should be tied to GND. | |
| 142 Boot0 == VDD -> bootloader on start, otherwise boot from Bank1 or Bank2 | |
| 143 depending on BFB2. | |
| 144 Bank2 contains the Fonts and should contain a proper test code in future | |
| 145 Bank1 is the main code (Bank1 is 1 MB too, usage as of Oct. 14 is 200 KB) | |
| 146 [..] Bootloader should be either UART or USB (on FS pins _only_) | |
| 147 USB HS to FS like on the Eval board does not work. | |
| 148 [..] Bootloader for the smaller CPU2 is implemented via the SPI used for DMA copy. | |
| 149 | |
| 150 ============================================================================== | |
| 151 ##### Connection to CPU2 (STM32F411 as of Oct.14 ##### | |
| 152 ============================================================================== | |
| 153 [..] Connected via SPI and DMA for every purpose. | |
| 154 two entire arrays are transfered for data security reasons | |
| 155 with respect to master (STM32F429) might interrupt internal | |
| 156 data copy in CPU2 (like hi byte, low byte, etc.). | |
| 157 [..] The entire life data is calculated in CPU2. Like tissues, CNS,... | |
| 158 Therefore the main unit is _not_ necessarily a Real Time system. | |
| 159 Simulation on the main unit can be executed without disrupting life data. | |
| 160 [..] SPI is triggered and timed by calling DataEX_call() in data_exchange_main.c | |
| 161 DataEX_copy_to_LifeData() does the transfer from buffer to variables used. | |
| 162 | |
| 163 ============================================================================== | |
| 164 ##### Menu, MenuEdit, Info ##### | |
| 165 ============================================================================== | |
| 166 [..] tMenu.c, tMenuEdit.c and tInfo.c is the system used. | |
| 167 logbook is part of Info not Menu. | |
| 168 The Info Menu is accessed by button 'Back' | |
| 169 The regular Menu is accessed by button 'Enter' | |
| 170 [..] Menu content is kept in frame memory for fast access. | |
| 171 There is no need to build pages if the 'Enter' button is pressed. | |
| 172 This is in contrast to MenuEdit pages. | |
| 173 [..] Button control for new pages (and pages in general) have to implemented | |
| 174 in tMenu.c, tMenuEdit.c or tInfo.c | |
| 175 | |
| 176 [..] ToDo (Oct. 14) Timeout for menus via Timer3 / IRQ 2 | |
| 177 | |
| 178 ============================================================================== | |
| 179 ##### specials ##### | |
| 180 ============================================================================== | |
| 181 [..] There was code for vector graphics from great demos | |
| 182 (peridiummmm and jupiter) that can be fitted again | |
