|
|
|
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
