Hi, are you sure to remove the line 'Serial.begin(115200);' in setup() and not change it to 'Serial.begin(9600);' or something else? I remove this line and compile it , a lot of error occured. Any advise. Thank you.

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.

@kenneth123 Just tried and logged in with no issues.

Hi @felmue
Friend, thank you very much for your interest in our problems.
Cheers.

Hi, I had the same problem as you, my M5stack did not connect or crash if you did it by force, for cons I solved my problem by installing a new firmware and changing USB port, I was on a HUB and now I'm using a USB port on my PC

Link of the firmware : https://github.com/botofancalin/M5Stack-MultiApp-Advanced

It is for M5StickC Plus. M5StickC is nearly the same:

@thrasher hi , maybe because the model file too big. you could use V-Training serve to Training a new Model ， then will be solve

@doublep hello, could you refer me to where you read that value from?

@m5stack
Could you please correct the UnitCamForUIFlow firmware as follows?
Set the WROOM-32 clock to XCLK=8MHz and the ov2640 clock to twice the current clock.

This solution has been found by Sohtamei in the following thread;
https://community.m5stack.com/topic/3649/unitcam-hw-issue-cannot-stream-video/8

Thanks a lot.

@ajb2k3
ESP-NOW uses only the MAC address of the station.
However, SoftAP is displayed as your own MAC address of ESP-NOW.
I want the MAC address of the station to be displayed.

The problem is that the received MAC address is different from your own MAC address.

I FOUND THE SOLUTION!!!
After diving into deep of operating system I figured out a possible solution which worked for me:

I had a usbserial.kext laying in /Library/Extensions/ and I figured out that it was also a WCH driver I deleted usbserial.kext and restarted the Mac again => no success I deleted CH34xVCPControlDriver.kext and CH34xVCPDriver.kext in /Library/Extensions/ and restarted again I installed another driver: FTDIUSBSerialDextInstaller_1_4_7 and had to confirm SIP integrity In system preferences -> security I had to enable access for the FTDI driver and saw another process pending named something with Quinheng As I remembered that Quinheng has something to do with WCH I ticked this process too and restarted I installed CH34xVCPDriver.pkg V1.7 again and restarted => no success I plugged in a CH340G device and suddenly a /dev/cu.wchusbserialXXX port appears in my Arduino IDE and is working with my CH9102 device Plugging out CH340G device continues /dev/cu.wchusbserialXXX working

Hope that this solution will work for other people too!

Hello @Pajdzian

I measure about 62 mA charging current (at the battery) when using M5Launcher and the same amount when running Cardputer UIFlow2 or Demo firmware (the one preloaded).

So I am curious: what other firmware did give you a slower charging rate?

Thanks
Felix

@vshymanskyy please, could you send schematic of IP56306 I2C connection? I try to connect to my (which should have I2C) - but she doesn't reply. I use external microcontroller with external supply. Also I connect SCL to 2nd and SDA to 3st pin pin of IP5306. IP5306 powered from li-ion battery.

Concise code for sure. I need all the speed I can get so it'll be Arduino for now.
I'm surprised you wouldn't see any flicker on the display since you print every frame, also surprised that there is no clearScreen preceding the print. I'm thinking the python print has a background.

@chriswr Ok solved.. disable the watchdog..

disableCore0WDT();
disableCore1WDT();

@cepics said in Step Motor Module:

can I use this motor with this module?

It looks like it should work but you would need to adjust the drivers. I don’t have one so I can’t say for certain but it is a 4 wire stepper

https://github.com/m5stack/GoPlus/blob/master/src/src.ino this is sourece code

@shintobi check out some of the scenes like ping-pong. It’s in a script on a GO.

The encoder signal is displayed very accurately and also evaluated very precisely. Of course also with the NXT motors and EV3 motors. I will see that I make a video the days once again where you can see how precisely he drives the set values.
@liemph
I will then connect a NXT motor and run it on different values of the encoder! The GlideWheel PF and RCX motor controller for NXT or EV3 cannot be mounted directly on the old motors, because it is designed for the power motors (on these it is mounted with two pins), but you can mount it somewhere in the system on the shaft of the motor. So you can make an encoder motor out of any Lego motor.

@Michael1968,

Yes, there it goes really very fast, I ordered the Base NodeSKU:M017 on Saturday. Yesterday he already went out. I am curious when he will be here but from the Netherlands it doesn't take so long after Siegen !
I can only recommend the shop !
