Hi, I am just trying to get a DHT11 sensor to play with me on a wemos d1 mini esp8266. I have 2 of them and both fail to read a value, that makes me wonder if I am the issue here as I still sometimes get the pin numbers wrong I am just hoping someone can tell me if I have connected it correctly or i...

Hmm i have seen watchdog being mentioned as well as power outage. watchdog still goes over my head, need to spend more time understandig what it is. I just erased and flashed another wemos mini D1 I have and tried with just the wifi connection script and the same crash happened. So far I have used 3...

Hi! Is this a common/expected issue? I have found several threads with similar issue but I have not found how to solve it yet? I get this error only when I am using a wifi connection. Using a wifi connection in my projects is the only reason I got started with micropython so now I am stuck from star...

I soldered a second wemos and tried to upload again. The result was exactly the same. Sometime when I use ampy to put file on it I get ampy.pyboard.PyboardError: could not enter raw repl If I abort and try again it works again and I can see the file on the wemos. But when I enter the repl through pu...

Hi! Keep running into odd issues it seem.. I have written a small util.py file that only include a function to connect to network import network def wifi_connect(): """Connect to the configured Wi-Fi network.""" sta_if = network.WLAN(network.STA_IF) if not sta_if.isconnected(): print('connecting to ...

Thank you guys for the suggestions. I am on a steep learning curve with microcontroller and micropython it seems. I finally found the error! I had connected the wire wrong to wake up the unit again so instead everything crashed. Once the wiring was resolved I was able to communicate with ampy again....

I have uploaded a main.py file. Whenever I press the reset button the the code is run again. But I cannot make any changes since the unit is busy ampy <any commands> serial.serialutil.SerialException: GetOverlappedResult failed (PermissionError(13, 'Access is denied.', None, 5)) So far I have to fla...

Ok, so i did some testing using the syntax from the doc RTC.irq(*, trigger, handler=None, wake=machine.IDLE) However my code produce an error: rtc.irq(trigger=rtc.ALARM0, handler=turn_on_led_callback, wake=machine.DEEPSLEEP) TypeError: extra keyword arguments given I am using a wemos 8266 but it onl...

Hi! I am working on a basic watering system. The plan is to control when to water and for how long with some sort of timer. For example "activate pump at time x for 15 seconds". Working with time in general is quite tricky so I am asking for advice. I dont want the time schedule to be hard corded, I...

Turns out nothing was wrong with wiring or code. I seem to have a faulty unit that just sometimes work. I had another one and that work fine everytime. Annoying when you spend so much time on it Oh well
