* Improved heap and PSRAM handling
- Segment `allocateData()` uses more elaborate DRAM checking to reduce fragmentation and allow for larger setups to run on low heap
- Segment data allocation fails if minimum contiguous block size runs low to keep the UI working
- Increased `MAX_SEGMENT_DATA` to account for better segment data handling
- Memory allocation functions try to keep enough DRAM for segment data
- Added constant `PSRAM_THRESHOLD` to improve PSARM usage
- Increase MIN_HEAP_SIZE to reduce risk of breaking UI due to low memory for JSON response
- ESP32 makes use of IRAM (no 8bit access) for pixeluffers, freeing up to 50kB of RAM
- Fix to properly get available heap on all platforms: added function `getFreeHeapSize()`
- Bugfix for effects that divide by SEGLEN: don't run FX in service() if segment is not active
-Syntax fix in AR: calloc() uses (numelements, size) as arguments
* Added new functions for allocation and heap checking
- added `allocate_buffer()` function that can be used to allocate large buffers: takes parameters to set preferred ram location, including 32bit accessible RAM on ESP32. Returns null if heap runs low or switches to PSRAM
- getFreeHeapSize() and getContiguousFreeHeap() helper functions for all platforms to correctly report free useable heap
- updated some constants
- updated segment data allocation to free the data if it is large
- replaced "psramsafe" variable with it's #ifdef: BOARD_HAS_PSRAM and made accomodating changes
- added some compile-time checks to handle invalid env. definitions
- updated all allocation functions and some of the logic behind them
- added use of fast RTC-Memory where available
- increased MIN_HEAP_SIZE for all systems (improved stability in tests)
- updated memory calculation in web-UI to account for required segment buffer
- added UI alerts if buffer allocation fails
- made getUsedSegmentData() non-private (used in buffer alloc function)
- changed MAX_SEGMENT_DATA
- added more detailed memory log to DEBUG output
- added debug output to buffer alloc function
* Fix bootloop if config missing/reset
Can't reset the config if there's nothing to reset!
* ESP8266: Commit ACTIONT_TRACKER
* Use consistent naming for backups and reset cfgs
Use 'rst.cfg.json' instead of 'cfg.json.rst.json' for configs that were
reset.
* Add a little more PSTR to bootloop handling
* added boot loop detection and config backup
* automatic OTA rollback if loading backup does not fix it
* added new file handling functions
* adding verification of json files, added config restore at bootup if broken
* added function to compare contents of two files for future use (currently not used)
- Photoshop-style segment/layer blending
- return of strip ABL
- remove global LED buffer in favour of segment-local buffer
- new effect blending modes/transitions
- custom palettes moved out of WS2812FX class
- increased limits (matrix size, LED RAM)
- added "rainbow"-mode colorwheel
- replaced palettes with gamma unmodified ones
- move gamma adjustment to last step before sending to LEDs
- Segment & WS2812FX class reorganisation (mutable members, reordered members, protected members)
* changed some parameters to "pointer to const", so compiler can better optimize code size and performance - because data behind a const pointer will never be modified by the called function.
* made setPixelColor `const`
* fixed a few potentially uninitialized local vars (the may have random values if not initialized)
* avoid shadowing "state" in handleSerial()
* plus a few very minor improvements
* trying to make the caching mechanism bulletproof.
`cacheInvalidate` is changed when
- autosave usermod updates presets
- a file was upload
* (coding style) fixed some unitialized variables
* use size_t instead of uint16_t -> prevents random behaviour (corruption) in case that JSON files get larger than 64Kbytes.
* use a constant for max large file space (was UINT16_MAX)
* reduced the scope of some functions and variables to "static" - avoids name clashes and may support better optimization by the compiler
* Use arduino-esp32 2.0.2 for ESP32-S2
LittleFS is merged into it.
* Fix filesystem error for ESP32-S2
Use platform of tasmota until upstream released it and
use board_build.flash_mode = qio
* Fix empty disk usage
* Add esp32s2_saola to default_envs
* Remove lorol LITTLEFS for esp32dev, too
* Revert "Remove lorol LITTLEFS for esp32dev, too"
This reverts commit 3586d5eef7.
* Remove -w (Suppress all warnings, including those which GNU CPP issues by default.) and add back in -Wall (Turn on all optional warnings which are desirable for normal code.) from build_flags
* Fixes warning: suggest parentheses around '+' in operand of '&' [-Wparentheses]
* Fixes warning: "CONFIG_LITTLEFS_FOR_IDF_3_2" redefined
* Fixes warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'uint64_t {aka long long unsigned int}' [-Wformat=]
* Fixes warning: enumeration value 'onoff' not handled in switch [-Wswitch]
* Fixes warning: "ntohl" redefined, warning: "ntohs" redefined, warning: "htonl" redefined, warning: "htons" redefined
- Original fix: 858f8f4ee9
* Fixes warning: unused variable 'mainSeg' [-Wunused-variable]
* Fixes warning: unused variable 'start' [-Wunused-variable]
* (untested!) Fixes warning: operation on '...' may be undefined [-Wsequence-point]
* Fixes warning: unused variable
* Fixes warning: unused variable and warning: narrowing conversion
* Fixes warning: unused variable
* Fixes warning: unused variable
* (untested!) Fixes warning: statement has no effect [-Wunused-value]
* Fixes warning: control reaches end of non-void function
* Fixes warning: unused variable
* Fixes warning: left operand of comma operator has no effect
* Fixes warning: no return statement in function returning non-void
* (untested!) Fixes warning: ISO C++ forbids converting a string constant to 'char*' and fixes warning: unused variable 'nPins'
* Fixes warning: deleting array 'dmxData'
* Fixes warning: unused variable
* Remove all warning suppression buildflags
