All my project sources *.py files is 15K I compiled *.py files into *.mpy with micropython mpy-cross utility for linux and got 8K of *.mpy Sent them to esp8266 flash with a command: mpy-cross Inc/NetHttp.py -o Inc/NetHttp.mpy .... .... ampy --port /dev/ttyUSB0 --baud 115200 put Inc In both cases (*....

In pure micropython ver 1.12 there is approx 32K of free memory to use. Earlier versions 1.9 had only 30k free. So thanks micropython team for great job to save 2K. It is a lot! I have already included asyncio, mqtt, http server, captive DNS, wifi connection, logging, settings saving, queues. This m...

Thatks Peter
with LabelEnd you are right

any idea about LabelA?

VladVons

I know all horrow stories about GOTO, but nevertheless.... under python for PC there is a 6k library "goto-statement" It is not small for ESP8266 how to exit from nested loop? def LabeledNestedLoop(aMax): for A in range(10): #LabelA for B in range(10): for C in range(10): print(A, B, C) if (C == aMa...

Two reasons: 1) Main is less code size It gives more free usefull RAM for tiny esp8266 (32K free pure memory only !) 2) Less WrongNamedCallers in a bullshits code By the way how to free memory from unused imports, classes, functions? Relative post was here, but no sucsess with it. https://forum.micr...

I use this trick for logging both message + caller

Code: Select all

def Log(aMsg, aCallerName = 'unknown'):
  # to minimize code size it would be good to get a aCallerName from a stack here
  print(aMsg, aCallerName )
  
def Func1():
  Log('Message1', 'Func1()')

def Func2():
  Log('Message2')

While button is in a pressed state the application is still alive (i see terminal screen) but freezed If i release a button than application reboots. So i want to u...
