Please follow this instruction and see if helps:

Observe whether there are any obvious physical damage marks on the device. Install the device driver: Windows: https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/drivers/CH9102_VCP_SER_Windows.exe macOS: https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/drivers/CH9102_VCP_MacOS_v1.7.zip Connect the device using a USB cable and open the device manager. Check whether the device manager page refreshes when the device is inserted, and whether a new device appears in Universal Serial Bus controllers. If not: If you are using USB C to C cable: First disconnect the StickCPlus, turn off the device, and then plug in the cable (press and hold the power button until the green light turns on to indicate that it is turned off). Or replace it with an A to C cable. If you are using USB A to C cable: "Try to change the data cable", "Try to reinstall the driver", "Try to change the PC". Reburn the factory firmware: https://docs.m5stack.com/en/guide/restore_factory/m5stickc_plus. The screen is still black after burning: Press and hold the leftmost button until the green light inside turns on, then plug in the USB cable Observe whether the screen is black but has a faint backlight, and whether there is a beep sound when pressing the button

@Zverik
that's a bit of weird, i think you should try flash the factory firmware to test out if that was a hardware failure

I've just uploaded it to a M5stack CoreS3 but the audio is very choppy like the streaming isn't smooth. Any way to adjust anything since there seems to be no other parameters except wifi?

Hi, When it will be back ?

Will EZ Data work in UIFlow 2.2.7 ? Because if not, i might have to redo entire work with UIFlow 1.0.

@kuriko
Thank you for your hint. However, I don't know how it could help to solve my requirements.
In M5StickC-Plus example, IMU will remain powered on and will send interrupt on gpio 35 on motion.
In my requirement, axp2101 could send interrupt on power-on (usb), but its interrupt pin is not connected to esp32.
AXP2101 usually wakes up esp32 by simply powering on esp32, it is not a real wake up by interrupt. Therefore, wake up by power-on (usb) works only if esp32 was powered off by axp2101 previously. I cannot power-off esp32 because it should also wake up on gpio interrupt from PIR.

Got it working with a different USB cable, and I didn't need to push any buttons to get it in to download mode. M5Burner worked fine.

To write Key A and Key B onto a WS1850S, connect the device to your PC and use compatible software. Place the MIFARE card on the reader, authenticate the target sector using the default key, and access the sector trailer block. Input your new Key A, access bits, and Key B in the correct format. Write the data, verify authentication with new keys, and ensure access settings are not misconfigured.

@scroggyg I also have the Tab5 and it says it accepts a Stamp Lorawan Module.
Does that Stamp LoraWan exist???

If you are using Windows 10, upgrade your Windows system to the latest version. Use other operating systems to compile (such as Linux distributions). First, make sure that "rom\miniz.h" exists in Arduino's ESP32 board manager files. Then try to manually change all paths containing #include <rom/miniz.h> to absolute paths. For example, #include "C:\Users\admin\Documents\Arduino\libraries\esp32-xxx\xxxxxx\rom\miniz.h"

@mdseldon
are you able to access the serial log?

@kuriko yes！I tried this but it is not the frequency-amplitude data?

@twigs said in Using M5Stack for Custom Signage Displays – Need Advice:

Hey everyone, I’ve been exploring M5Stack modules for a custom signage controller project—curious if anyone here has experience using UIFlow or MicroPython for real-time display updates?"
"Also open to suggestions on the best units for LED or TFT screen integrations—appreciate any tips!

For a start, Micropython is not a realtime language, it is an interpreted language.

The biggest issue for signage is that of memory and ram, the bigger the sign, the more the memory is required.
