Hello @houkensjtu
ok, I see. In UI-FLOW you could use an Execute code block and add something like this for deep sleep:
import machine
#sleep for 10 seconds
machine.deepsleep(10000)
or light sleep:
import machine
#sleep for 10 seconds
machine.lightsleep(10000)
BTW: I found a nice tutorial about MicroPython and sleep modes here.

Hi,
I have a project with:
1 DS18B20 sensor (3 wires)
2 water flow meters (3 wires)
2 relays
I will probably use the M5 PLC module to prototype the circuit.
What is for you the best pins to use for sensors and relays?
Thanks
I'm having a problem with my M5Go, it was working perfectly for weeks but since some hours i can't connect it to the PC anymore.
I tried 3 different wires and 2 different PC's
The CP210 driver has been reinstalled and all Software related things have been checked several times
It doesn't even show up in the device manager anymore....
Has anyone had a similar problem or has an idea how to solve it?
Thanks in advance
Hello
I try to execute the Maixpy example: "Button" in https://github.com/m5stack/m5-docs/blob/master/docs/en/related_documents/M5StickV-Maixpy.md
unsing MaixPy IDE, and I have the error (line 12):
AttibutError: 'Board_info' object has no attribut 'BUTTON_A'
Note:
I burnt my M5StickV before with the latest maixpy firmware (maixpy_v0.5.1_103_gf9bb0bb.bin)
My MaixPy IDE (v0.2.5) is configured for using my M5StickV board (tools>Select Board>M5StickV)
Is there something to configure for using the "Board_info" lib with the M5StickV configuration ?
Hello @ckuehnel
Without opening M5CoreInk you probably cannot measure battery voltage with a multimeter. However you can use GPIO35 to read the battery voltage. Check out float getBatVoltage() here.
BTW: I've opened my M5CoreInk today and added some photos to my page (link below). Measuring power consumption in light sleep, deep sleep and shutdown will be next.

I stumbled on this restriction again, and dug a bit deeper in the issue.
It appears that the hardware is not limiting the baudrate, but the M5Stack library. More specifically, M5.begin();
Luckily, you can skip the UART init, and do it yourself like this:
M5.begin(true,true,false);
Serial.begin(2000000);
Serial.flush();
And now it works for 2000000 baud.
Hello @AndyT
hmm, strange, if anything I'd expected the M5Stack Gray to work with low brightness level and the M5Stack Black to not behave due to the fact that the M5Stack Gray has additional hardware (e.g. IMU) consuming power to keep the device powered on.
That said, I suspect the IP5306 switching off due to too light load. Try to add the following statement before going into deep sleep. It should prevent the IP5306 from shutting down under light load.
M5.Power.setPowerBoostKeepOn(true);
Happy Stacking!

@sparkinman
Check that:
You have added the M5Core2 library and are doing #include <M5Core2.h> and not using M5Stack.h. Until they merge it my Pull Request and release a new version, my version is more like it will be, better documented and has graphical buttons. (Simply clone it or get the zip file and unpack so that M5Core2 is a subdir of your Arduino libraries dir.)
In Arduino Preferences, you have added https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json as an "Additional Board Manager URL"
Make sure you then select M5Stack-core2 from the "Tools / Board / M5Stack-Arduino" menu.
If this is all good, then you should be able to run one of the examples from the "File / Examples / M5Core2" menu.
Hello @veryalien
Sorry to hear about your troubles.
I looked into the factory test program today and got it to compile and running after enabling PSRAM, the above mentioned fix in SetLDOVoltage() and some cleanup of the old Wire vs Wire1 fight that seems to come back every now and then. I wished the developers could make up their mind and always use Wire for internal I2C devices. Oh well.
The factory test code does something interesting regarding vibration motor voltage. During the startup sequence it is first set to 2 volts, then the motor is quickly turned on and off again and then later on it is set to 3.3 volts (not sure why though). When testing the vibration motor from within the settings menu the latter voltage is used.

@efried said in Snap in fixture?:
I can't find such in the webshop.

thanks
This isn't an M5Stack product, that is a user created free to download addon that needs 3D Printing.
To avoid possible conflicts with my app, I tested with Wifi Examples from ESP-IDF repo:
https://github.com/espressif/esp-idf/blob/master/examples/wifi/getting_started/station/main/station_example_main.c
Sorry for this missing point.
it's a library to control a sensor, I had already built my custom blocks that worked with that library, but when I updated everything I was unable to make it go.
so do I have to import the library into the / flash root?
and then?
Hi @m5stack
you could pip install a pyserial module to solve it.
I tried that but the problem persists. As a quick fix, I just flashed it using a window virtual machine.
the LED always RED? which program are you use?
Yes, but after I flashed the new firmware everything is behaving well.
which program are you use?
It turned RED, after I tried to flash it with the newer esptool (2.8) as I showed in my initial topic
we will fix this bug in next version.
🤞🏻
Have a nice day
@robalstona excellent. Thank you for the clarification. It’s logical, and I agree that I don’t require anything higher, but I wanted to make sure for safety’s sake.
