UART Gnss: Added fletcher calculation:
Communication is verified using the Fletcher check. In the example code the commands were har coded including the check bytes. To make definition of new commands easier the check bytes are now calculated at runtime. This may be referted to hardcoded values once the implementation is getting a mature state.

| 38 ##### bootloader specific ##### | |
| 39 ============================================================================== | |
| 40 | |
| 36 | 41 151130 hw sleep on button3 |
| 30 | 42 (MX_tell_reset_logik_alles_ok() + DataEX_call() in endlos loop) |
| 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 ============================================================================== | |
| 92 [..] For everthing slow without importance to be 'in time'. | |
| 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. | |
| 102 Be carefull to release every frame | |
| 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. | |
| 130 This prevents erratic behaviour if several changes | |
| 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 | |
| 145 Therefore there are differnent functions | |
| 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 | |
