سلام من تازه بورد node mcu esp8266 گرفتم ولی هنگام اپلود برنامه به خطای زیر میخورم
Executable segment sizes:
ICACHE : 32768 - flash instruction cache
IROM : 248276 - code in flash (default or ICACHE_FLASH_ATTR)
IRAM : 27273 / 32768 - code in IRAM (IRAM_ATTR, ISRs...)
DATA : 1504 ) - initialized variables (global, static) in RAM/HEAP
RODATA : 1948 ) / 81920 - constants (global, static) in RAM/HEAP
BSS : 25824 ) - zeroed variables (global, static) in RAM/HEAP
Sketch uses 279001 bytes (26%) of program storage space. Maximum is 1044464 bytes.
Global variables use 29276 bytes (35%) of dynamic memory, leaving 52644 bytes for local variables. Maximum is 81920 bytes.
