USB communication
-
Dear All,
I like UIFlow but I am not an expert of Python. I have always programmed through the standard Arduino IDE.
I need to interface my M5Stack Core 2 with MegunoLink. This can be easily done if I use the standard IDE, but I am not able to do it with UIFlow.
Basically I need to send to my PC through the USB a set of strings such as: {XYPLOT|DATA|Name|x|y}
Could you help me?
Thank you very much

Dear felmue,
At first thank you very much for your answer. I apreciate this.
I tried. It works (!) but I have some problems. First of all, the data transmission is really slow. I tried to modify the row:
print((str(((str(((str(((str('{XYPLOT|DATA|Analog Measurements|') + str(tt)))) + str('|')))) + str((adc0.read()))))) + str('}')))
with
print("{XYPLOT|DATA|Analog Measurements|}, tt, "|", adc0.read(), "}")
but without success.
Another problem is that when I open the USB communication from my software on the PC the M5 has a reset...
Could you help me?
Thank you! -
Hello @brvus76
I don't really know why the communication might be slow. I can only guess that UIFlow firmware maybe has some safeguards in place to prevent serial from flooding the line.
I guess that your software on the PC manipulates the control lines (CTS, etc.) on the serial port in a way which triggers the auto download / reset mechanism in M5Core2. Unless there is some setting in your software to configure that behavior I don't think there is much you can do.
Thanks
Felix
