All of the IO pins have interrupt/pwm/I2C/one-wire support except D0 only pins 0, 2, 4, 5, 12, 13, 14, 15, and 16 can be used

Dateiname: sc.py
Dateiinhalt:
def echo(content)
  print(content)

print("Start bzw. Ausgabe nur bei import sc")
echo("Wird auch beim import ausgeführt. Danach nur über sc.echo() erreichbar")

Also möchte man seine Funktionen auf repl ausführen, sollte man den Dateinamen und Funktionsnamen kennen, damit man jederzeit auf sein Programm zugreifen kann.

Textdatei lesen (schreiben):
f=open("D:\\new_dir\\multiplelines.txt","r")
#Use print to print the line else will remain in buffer and replaced by next statement
for line in f:
    print(line)
f.close()

PLatz auf ESP8266:
==================
import uos
fs_stat = uos.statvfs('/')
fs_size = fs_stat[0] * fs_stat[2]
fs_free = fs_stat[0] * fs_stat[3]
print("File System Size {:,} - Free Space {:,}".format(fs_size, fs_free))

NETZWERK:
=============
import network

wlan = network.WLAN(network.STA_IF) # create station interface
wlan.active(True) # activate the interface
wlan.scan() # scan for access points
wlan.isconnected() # check if the station is connected to an AP
wlan.connect('essid', 'password') # connect to an AP
wlan.config('mac') # get the interface's MAC adddress
wlan.ifconfig() # get the interface's IP/netmask/gw/DNS addresses

ap = network.WLAN(network.AP_IF) # create access-point interface
ap.active(True) # activate the interface
ap.config(essid='ESP-AP') # set the ESSID of the access point

def do_connect():
    import network
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print('connecting to network...')
        wlan.connect('essid', 'password')
        while not wlan.isconnected():
            pass
    print('network config:', wlan.ifconfig())

MQTT Mosquitto:
================

mosquitto_pub -h test.mosquitto.org -t dfdfdf -m "Hello Raspberry Pi"
mosquitto_sub -h localhost -v -t test_channel
