Re: Flashing error? (memory allocation failed)

You need to include the font files (and as many other files as you can) as frozen files. Thanks from me as well. I have some reading up to do and then hopefully it'll work for me too. I have a "wifi_connect.py" which is importet in the boot.py. I should freeze that too? Anything else? Since you sai...

Re: Flashing error? (memory allocation failed)

You're talking to a beginner :lol: First I will look up allocate and array, since I'm not a native english speaker but I'm afraid after that I won't know how to do what you are asking :oops:

Re: module documentation (ssd1306)

Thanks again. Okay, I now get how it's supposed to work. However I'm sadly encountering problems. I've read a lot, tried a lot, changed a lot. the writer.py seems to be the troublemaker. For example: from writer import Writer import courier20 Traceback (most recent call last): File "<stdin>", line 1...

Countdown timer

Hello, I'm trying to write my first real MicroPython script. It's supposed to be a timer that starts to count down from 60, when a button is pushed and visualise it on a display. This works fine so far: import machine from machine import Pin, I2C import ssd1306 from time import sleep i2c = I2C(-1, P...

Re: umqtt.simple trouble

Well this: c = MQTTClient("umqtt_client", "localhost") can't work on the esp8266 because the broker is not running on localhost, which would be the esp8266 itself. It has to be the IP-Adress of the mqtt broker. Thanks, that was my initial suspicion but I forgot the " " :roll: :oops: Now it works, t...
