Introduces new memory allocation functions, based on wled#4895 by @DedeHai
* keep a minimum of 15KB RAM available to UI - improves stability
* S3/S2/C3 automatically use "fast RTC Ram" for small data (reduces fragmentation)
* auto-detects PSRAM (or no PSRAM) when firmware was built with -D BOARD_HAS_PSRAM
* d_malloc() and d_calloc() prefer DRAM if possible (faster), but fall back to PSRAM when free RAM gets low.
- if log file cannot be created, switch to serial logging
- fixing a broken format string
- usermod_arti: avoid to copy more than what fits into the buffer
- check that programName is not too long (fileNameLength-7 is the limit)
- try to fix a memory leak, as programText must be free'd in case of error.
@ewoudwijma please review my changes, I'm not 100% sure I did it right.
Add ARTI-FX to esp8266_4MB_M (experimental!)
Arti.h
- FREE_SIZE ESP.getFreeHeap() for 8266
- define asChar(x) to print to Serial/File depending on ESP32/8266
- artiPrintf: print to USER_PRINTF (experimental)
Arti_wled.h
- add ARDUINO_ARCH_ESP8266 to ARTI_ARDUINO
- add soundPressure
usermod_v2_artifx.h: use FREE_SIZE
