controlling relay HELP!!!!!

EagleFPV

im trying to control a relay using the m5stickc plus2 on g26

This is my code:

from M5 import * # Correct import for M5StickC in UIFlow 2.0
import time

Set GPIO pin for relay control (changed to GPIO 26)

RELAY_PIN = 26 # GPIO 26 for relay control

Initialize the relay pin as an output

relay_pin = M5.Pin(RELAY_PIN, M5.Pin.OUT) # Correct way to initialize the pin

Function to turn on relay

def turn_on_relay():
relay_pin.value(1) # Set relay pin to HIGH (turn on)

Function to turn off relay

def turn_off_relay():
relay_pin.value(0) # Set relay pin to LOW (turn off)

Main loop

while True:
try:
# Check if button A is pressed
if buttonA.isPressed():
turn_on_relay() # Turn on relay when button A is pressed
lcd.fill(0) # Clear the screen
lcd.text(50, 50, "Relay ON", color=lcd.WHITE, font=FONT_Default)
else:
turn_off_relay() # Turn off relay when button A is not pressed
lcd.fill(0) # Clear the screen
lcd.text(50, 50, "Relay OFF", color=lcd.WHITE, font=FONT_Default)

    time.sleep(0.1)  # Small delay to avoid overwhelming the system
except Exception as e:
    lcd.fill(0)  # Clear the screen on error
    lcd.text(50, 50, f"Error: {e}", color=lcd.WHITE, font=FONT_Default)
    time.sleep(2)  # Wait for a moment before trying again

this is the error im getting on uiflow2.0

Hello @EagleFPV

please have a look at the example I've just created in UIFlow2 Project Zone called: M5StickCPlus2_GPIO26_On_Off_UIFlow2.2.0

Thanks

@felmue hola he visto que ayuda mucho a la comunidad.
¿Podria ayudarme a saber porque me sale este error?
estoy intentando conectar mi m5 tough a mi wifi pero me sale el siguiente error
E (328421) wifi:NAN WiFi stop
este es mi codigo
import network

wlan = network.WLAN(network.STA_IF)
wlan.active(True)

Borra configuraciones anteriores

wlan.disconnect()
wlan.active(False)
wlan.active(True)
wlan.connect("TRC2021", "UoU@%0r3t6QON6ua")
if wlan.isconnected():
print("Conectado a WiFi con IP:", wlan.ifconfig()[0])
else:
print("No se pudo conectar a WiFi")

Hello @sat-informatica

below code works for me:

import network

wlan = network.WLAN(network.STA_IF)
wlan.connect('SSID', 'Password')
label0.setText(str('Connecting...'))
while not (wlan.isconnected()):
  pass
label0.setText(str('Connected'))

Thanks

Hello, I'm going to tell you everything I know and have tried so far.
I'm experiencing an issue with my M5 Hard devices. A few months ago, I purchased a couple of M5 Hard units for an MQTT data transmission project. I developed it in UIFlow 2, and everything worked perfectly.

Recently, I bought more M5 Hard devices to expand the project, but now I’m facing a problem: when I install the firmware and try to connect them to WiFi, they won’t connect. I have tried the following without success:

Reinstalling the USB drivers on my computer.
Resetting the device to factory settings.
Reinstalling the firmware.
Trying different WiFi networks.
Temporarily disabling the firewall and antivirus.
Using different firmware versions.
Checking the router configuration and connection parameters.
Despite all these attempts, I still cannot connect them to WiFi. I’m getting the following error:

arduino
Copiar
Editar
E (328401) wifi: sta is connecting, return error
Traceback (most recent call last):
File "<stdin>", line 19, in <module>
File "<stdin>", line 12, in setup
OSError: Wifi Internal Error
Additionally, I’m also getting this error:

nginx
Copiar
Editar
E (328338) i2c: i2c driver install error
I don’t believe this is a network issue (firewall, antivirus, etc.) because, as I mentioned earlier, I have successfully programmed and connected other devices without any issues.

I would really appreciate any suggestions or help.
