@jcabad100 And I thought that was just me.
If you have facebook, join the official M5Stack group link text and drop them a message.

Sorry, the FB group needs to be added to the FAQ.

@zhouyangwen Thanks. This is works. Now i am abo

@lurk_ Because there are SY8089, RT9182 chip between BAT pin and ESP32_VCC, in order to transfer high voltage to 3.3V.

So you need a battery with higher voltage capacity.

Thank you very much!

@lukasmaximus said in [Solved]Official Grove cables - buckled or unbuckled?:

Just a caveat guys, beware that some vendors of the grove cables have the yellow and white wires switched so if you find your units aren't functioning correctly remember to check the cables first.

@lukasmaximus Thanks, i will add that to the book.

@yellowelise Really sorry about that. It's my fault. WEIGHT does not communicate with core through IIC.

@jpilarski
If you want to realize face recognition function with F camera, you just need to change the pin map that is corresponding to F camera.

@cepics Do you have some manual sheet of this lidar sensor?

Hello @cepics 20 pulse each way

@rolandp Open? Do you mean to open the casing of the unit?

@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

in the firmware there is the option for this but you will need to edit the firmware, recompile it and upload to the camera.

I tested a hub device attached to port A with a few 100cm grove cables and I was able to successfully read the i2c address of the ENV sensor and also others. I tested with the i2c_tester arduino program https://github.com/m5stack/M5Stack/blob/master/examples/Advanced/I2C_Tester/I2C_Tester.ino perhaps its just an isolated incident.

@playthegame thank you for help!
I updated esp32-arduino with this link - nothing happens
The same result - just 0x68 in I2C scanner listing(

@lukasmaximus
That’s what I needed to know. Thanks!

@yellowelise

I was glad that I could understand why I could not get the data.
Thank you.

@ajb2k3
Appreciate you!
