@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!

Thank you. I will try it again after buying the wire
