file 'main.py' is edited under ESPLORER, and transfered to the esp8266.
At RESET, it did not work.
the solution must be added an EOL ('\ n') to each line.
example:
import time\n
import machine\n
pin = machine.Pin(2, machine.Pin.OUT)\n
print('Hello world! I can count:')\n
i = 1\n
for i in range(10):\n
pin.low()\n
time.sleep(0.5)\n
pin.high()\n
time.sleep(0.5)\n
print(i)\n
so for the developper... could you automate this feature! Thank you in advance.
