@BobPossible same error, any solutions?

Ok, it worked finally. At least, I needed to use module_llm.melotts instead of module_llm.tts.

The model specification in tts_config doesn't matter for my case. It picks melotts-en-default somehow automatically even though the default value is melotts_zh-cn.

The module is very unstable when the controller is powered on. It requires several clicks of the reset button until it finally speaks. (The return value of melotts.inference is -97 when it's successful.)

@simondid have you even tried to look it up yourself? Google's first hit is literally this thread from April, including a full ESPHome config.

ESPHome also has a draft PR for including EPDiy as a generic display platform, and EPDiy itself has a PaperS3 pull request, which will allow the BMI270 component from the above thread to work (currently EPDiy tries to import some legacy code that breaks I2C, as patrick3399 used a custom fork of EPDiy that isn't exactly up to date).

@robski
it failed at 2%

have you tried to use M5Burner and "erase" option first? have you tried to load any simple Arduino code? or any available EasyLoader project from M5 product page?

@sapphire said in Tab 5 screen flicker after firmware update:

@Jomac If you watch the video, I have this little defect that doesn't happen often (a flashing).

The link doesn't work for me

Well I flashed the firmware several times and also flashed a couple of apps on M5Burner and nothing made any difference, everything just flickered so I switched off and left it for the night, next morning I was going to video the issue and when I switched on my Tab 5 again, the fault had cleared.

The Problem seems to still persist. Had the same issue and solved it this way.
Thanks @Dan-Perren and @teastain for the solution!

Okay, posting to help others as I did find the solution to this. As the error message states, the binary has to be suid root. You can get it going by typing:

sudo chmod 4755 bin/chrome-sandbox

From wherever you installed M5Burner. This, and adding the current user to the dialout group, should really be part of the installation instructions. I can't see how anyone on Linux would avoid doing both of these steps.

Now I if I can figure out why the Tab5 is bootlooping i'll be up and running...

I'm curious—will the iOS version of EzData support the same modules and data types as the M5Stack Core devices? Also wondering if there's going to be integration with iCloud or local storage for exporting logs. I’ve been exploring some related iOS app development workflows, such as those outlined at Idea Maker, and wondering how closely EzData aligns with those practices. Looking forward to seeing how it develops.

@robski said in Cardputer Driver Issues:

do you use m5burner?
if so what com port it shows there when you connect cardputer?
also what com port it is showing when cardputers on/off switch is in off and then you press and hold BOOT btn and then connect usb?

It depends on how it feels, sometimes it will connect on Com 4 and other times on Com 9???

thing is that comport you see with just connecting cardputer to usb is one of two available

second comport (needed for programming) is visible when on dead device you press and hold boot button G0 and then connect to usb

For the M5Stack Core2, Grove Port A uses I2C on GPIO 21 (SDA) and GPIO 22 (SCL). However, when using a Pb.HUB, you're communicating with the hub over I2C, and each connected unit (like relays or RGB) is addressed virtually via the hub.

Since openHASP doesn't natively support Pb.HUB devices, you can’t directly control GPIOs through it. Instead, you’d need custom firmware or integrate via ESPHome or Arduino to bridge Pb.HUB control with openHASP.

TL;DR: GPIO 21/22 for I2C, but control of devices via Pb.HUB needs extra handling outside openHASP.

@teastain

Here the answer:

M5.Lcd.print("Temp:"); M5.Lcd.print(t,0); M5.Lcd.print(char(247));M5.Lcd.println("C");

I guess you have found it meanwhile, but perhaps it is useful for others.

Hey @roanevic, just jumping in here, I’ve tried that same setup recently. The example code Kuriko linked is a good starting point:
https://github.com/m5stack/M5-RoverC/tree/master/examples/RoverC_JoyC_Remote

It’s designed for StickC, StickC Plus, and the StickC Plus2, so it should work with your hardware. Just make sure you have all the necessary libraries installed (like M5StickCPlus2, RoverC, and JoyC) in the Arduino IDE. Let me know if you hit any snags setting it up.

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?

Hello @daniel-edge456

in UIFlow2 v2.2.6 using touch blocks for M5Paper and then look into the Python tab I get the following code to get touch coordinates:

if (M5.Touch.getCount()) > 0: x = M5.Touch.getX() y = M5.Touch.getY()

doing the same with power blocks I get:

Power.deepSleep(1000, True)

to put M5Paper into deep sleep.

Thanks
Felix

@jgude said in cannot connect M5capsule:

@robski yes indeed.. but i get the fatal error it cant connect to espressif device, no serial data received. Do i need to clean it first somehow? Lools like it cannot get mac when i try to use the burn button

try erase first before burn
pressing boot booton on power up is important step on firmware operations
