Thank you very much for your answer.
I use Arduino

Dear All,
I have an SHT31 (adafruit, with Grove connector).
How can I connect it to my Atom?
Can I use the G26/G32 pins?
Thank you and best regards

Good evening.
Is there the possibility to acquire some data, save it on an SD card and send it to an external storage service, such as GDrive or Dropbox?
Could be possible to do it with UIFlow?
I have a Core2 system.
Thank you very much and best regards

Dear all,
I need a better resolution for a project and I have seen that the internal ADC of the ESP32 is really noisy. So I ordered an ADS1100 for my Core2.
In the meantime I tried to connect an ADS1100 hat (that I bought for an M5Stick).
I connected it to the Port A of my Core2

Here the code:

from m5stack import *
from m5stack_ui import *
from uiflow import *
import time
import unit
screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)
adc_0 = unit.get(unit.ADC, unit.PORTA)
label0 = M5Label('Text', x=126, y=113, color=0x000, font=FONT_MONT_14, parent=None)
while not (btnA.isPressed()):
label0.set_text(str(adc_0.voltage))
wait_ms(1)

When I upload I read:
ADC unit maybe not connect

Any suggestion?
Thank you!

Happy new year to everyone!
I am working with UIFlow (and uPython) to allow an UDP communication with a software on my PC.
I need to send a certain string over my network and this is the code that I wrote:

from m5stack import
from m5stack_ui import
from uiflow import
import wifiCfg
import socket
from easyIO import
screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)
wifiCfg.doConnect('NET', 'PSW')
udpsocket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
udpsocket.connect(('', 52790))
while True:
udpsocket.sendto(str((analogRead(36))), ('255.255.255.255', 52791))
wait_ms(1)

Everything works, but the communication is really slow, less than 50 messages per second.
When I use Arduino IDE, I can do the same at a sample rate of 500 messages per second.
Is this a limitation of uPython or do I commit an error?

Thank you very much and best regards

Good morning.
I am using the dual core function on my Stack 2, so I cannot use UIFlow, but Arduino.
I need to save on SD with one core and read with the other.
Is there an example on how to write (and read) on an SD card with M5Stack2.h library?
Thank you

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!

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
