More screen pages for M5Stack Core in UI window would be very helpful.
We have to place more than 130 text labels on different screen pages.
I would like to have for each page I am creating a separate screen, so that I am able to arrange all the labels.
Probably it could be also very helpful to enable and disable a layer number of the labels.
So, if I give all the labels on one page the same layer, it would be possible to disable all at once by a "disable layer" function in program code.
Just a short feedback.
I tested now the new RS485 to TTL converter.
It is working well together with the smart meter. Now communication is possible. All voltage levels are much higher.
The COMMU module is rubbish! Should not be used for RS485. I lost a couple of hours to fix this issue.
Now I have the issue to convert the float values from the smart meter into decimal / integer.
Any idea, how to do this with UIflow? is there a function available?
Ich habe ja jetzt fast 2 Stunden versucht das Programm irgendwie wieder angezeigt zu bekommen.
Letztendlich habe ich dann doch noch einen einzigen englischen Hinweis gefunden, der sich mit meinem Problem deckt.
Ich hatte nämlich einen Custom Block verwendet, der sich nicht automatisch lädt und somit das Laden des Programms abgebrochen wird. Es war der Custom Block für den Sensor DS18B20.
Das Erbärmliche dabei ist, dass UIflow keinen Hinweis ausgibt, bzw. dass z.B. ein Custom Block nicht geladen werden konnte bzw. zuvor geladen werden muss. Irgendeine Rückmeldung wäre auf jeden Fall extrem hilfreich gewesen und hätte mir etliche graue Haare erspart ...
Vielleicht hilft das dem ein oder anderen mit dem gleichen Problem.
Hallo Leute,
ich habe ein riesiges Problem.
Habe jetzt zwei Tage an einem Programm in UIflow für den Core 2 gearbeitet (im Chrome Browser) und immer wieder abgespeichert, auch unter anderem Namen.
Heute habe ich das Programm geladen, aber der gesamte Inhalt ist weg.
Die Datei hat noch 66kB, sollte also noch den Code enthalten. Im Editor scheint der Code der Blöcke noch vorhanden zu sein, er lässt sich in UIflow aber nicht mehr öffnen. Hier ein Ausschnitt:
Bin gerade ziemlich am Verzweifeln, da ich mir wirklich zwei Tage lang den Kopf zerbrochen habe, um ein Problem zu lösen.
Wenn ich auf die Python Ansicht wechsle, bekomme ich nur die Initialisierungen angezeigt.
Das Hauptprogramm fehlt komplett.
I found a workaround meanwhile with if-else.
It is not nice, but it´s working:
I convert the DAC Value into a String.
Then I check, if it is "None", if yes I send a 0 to the DAC.
If DAC Value is not "None" I convert it back to integer and send it directly to the DAC.
Hello,
I am working on a simple program.
I receive a value between 0 and 1000 by MQTT and convert it to a digital value from 0 to 255.
Then I want to put it on the DAC channel 0.
But if I want to proceed with the digital value within the main loop I get the error "Can´t convert NoneType to int".
I understand that this is a NoneType, which can´t convert into an integer, but I need to work with the digital value in the main loop, because I have to do some calculations (filtering), which is not possible in the MQTT function.
How can I solve this issue?
Thank you so much for this example. That´s what I am looking for.
It is not as comfortable as I expected, but it works. :)
@holofloh
Thanks so much for your explanation and ideas!
But I mean, is there no way in UIFlow (Blockly) to make the m5stack core accessable by IP from local network to get some data?
Just only to make the data vissible on internet browser? I would like to show real data, current status of the battery for monitoring in case of grid power loss.
I want/have to use Blockly, because I don´t have much time for programming in Python and I realized already some functions with UIFlow Blockly.
@ajb2k3 I will try it too, later today.
I now found the "remote+" block in UIFlow, which provides the function I am looking for, but it works only with access to external server. So, without internet access it is not working anymore, right?
Didn´t realized EZData. That could be an alternative solution.
But as I understand, internet is needed, which could be a problem for my project.
I want to read out a big battery, which must be accessable even if power from grid (and internet) is missing.
I am not sure how to realize a website to show sensor data.
For example:
I have a m5stack core which measures several temperatures and voltages.
Then I want to open a website on local network, where I can see all the data which are provided by m5stack.
How to start with UIFlow? Just only to show one sensor value on a small website, which is provided by m5stack via WLAN.
I have to convert a float value into decimal for modbus application.
I would like to realize this in UIflow.
Is there any function available or perhaps a program flow code?
Is it in general possible to realize this in UIflow blocks?
Just found an information how to create a custom block with Python.
Perhaps it already exists a m5b file? Otherwise I will try to create an m5b file.
Any other idea, how to convert float to decimal in UIflow?
Added:
I am reading out a smart meter with M5stack and UIflow:
The result is a floating point format value, here 17008.
Converting into decimal is not available in UIflow and converting into an integer value is not working, as expected.
Therefore the second value on display shows nothing (only default text).
Just a short feedback.
