Hi,
Example in MicroPython:

...
def setup():
  global wlan, http_req

  M5.begin()
  wlan = network.WLAN(network.STA_IF)
  if wlan.isconnected():
    print('Connected')
  http_req = requests2.get('https://test/test.php?val1=aaa&val2=bbb', headers={'Content-Type': 'application/json'})
  print(http_req.status_code)

And UI Flow2

Hi, I used the chat, but it didn’t help.

I’m using a similar code with Pulse mode:

AtomS3 Lite + QRCode2 Base = 230mA
AtomS3 Lite + QRCode1.1 Base = 75mA

That’s too big of a difference when using a battery.

import os, sys, io
import M5
from M5 import *
import time
from base import AtomicQRCode2Base

base_qrcode2 = None

def setup():
  global base_qrcode2, data

  M5.begin()
  base_qrcode2 = AtomicQRCode2Base(2, 5, 6, 7)
  base_qrcode2.set_trigger_mode(base_qrcode2.TRIGGER_MODE_PULSE)
  base_qrcode2.set_trig(0)
  time.sleep_ms(30)
  base_qrcode2.set_trig(1)
  print('take measurements')


def loop():
  global base_qrcode2, data
  time.sleep_ms(30)

Hi, I’m using the AtomS3 Lite with the QRCode2 Base.
The QRCode2 draws a high current of around 170 mA at 5 V and starts to heat up after a few minutes, even in pulse mode.

Is this normal?
Is there any way to reduce its power consumption?

What is the difference in using AtomicQRCodeBase with the functions start_decode(), stop_decode(), and set_trig(...)? What are the advantages of each approach?
