@felmue said in Core2 MBus Power Mode 5V Output AXP2101 / AXP192:

M5.Power.setExtPower(true/false)

Hi Felix

Thank you so much for your response and the help!
I tried to change the code (I use UI Flow 1 and MicroPython), unfortunatelly there always occur errors… Is there maybe a library missing?

If I use the function: M5.Power.setExtPower(true/false) following error occurs:
Name ‘M5’ isn’t defined

If I use the function: power.setExtPower(true/false) following error occurs:
‘Axp2101’ object has no attribute ‘setExtPower’

Thanks!

Couldn't decide, so I bought both lol.

Each seems to have some different strengths - the Fire has more ports, the cool magnetic base and physical buttons that often work better than touchscreens. As such it's great for tinkering. But the Core 2 seems a bit more 'polished' for portable applications.

@ajb2k3 Thanks for the response. Yes, I had found these before, but there for the FT6336U there is only an .xlsx document with a very brief description of the chip registers.

I am looking for a bit more detail...

@felmue thanx a lot! I use UiFlow1.1 and an example for LED control in python is here:

from m5stack import *
from m5stack_ui import *
from uiflow import *
import i2c_bus
import time

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)

i2c0 = i2c_bus.easyI2C((21, 22), 0x00, freq=400000)
i2c0.addr=(0x34)
while True:
i2c0.write_u8(0x69, 0x05)
wait(1)
i2c0.write_u8(0x69, 0x35)
wait(1)

@cchakons The error message you have implies that you have the wrong firmware selected for the stick Cplus2

@ajb2k3 Thank you soo much!
I turned off the VPN, and then it worked.

Hello @G3D_Design

please have a look at this simple RTC alarm trigger example in the UIFlow2 Project Zone: M5Core2_RTC_Alarm_Trigger_UIFlow2.1.1

Thanks
Felix

@virgile Have you charged the battery?

@Balboa yes and it can be used to send data it can not be used as a WiFi modem.
You can use it to receive data and commands from sensors to send to the internet just not browse internet

@themaker did you erase the firmware before writing?

@Revilo_oli
With some testing it was found that the core 2 was faulty and it had to be replaced

You can’t directly but if you use thonny, you can retrieve the Micropython code from the controller as its save on the controller as pure text

Looking at the schematics, the RST pin if pulled low, will do the same thing as if S1 is pressed. I assume S1 is the reset button.

I don't have a CORE2, but from experience with some other M5Stack products the function of the reset button depends on whether the device is on external power (e.g. USB) or on battery power.
External power: restarts , battery power: shuts down. (but that is something you can test yourself)

Ok, I found the issue and it's a stupid mistake on my part. I had forgot that M5 Stack is the company, not the device name and had downloaded the M5Stack examples, which aren't aimed at this particular device. When I started using the M5 Core2 library, it looks like it is actually working, so that's good news. Sorry for the confusion!

@felmue Thanks a lot. This solved my project
