What is the Hall sensor actually measuring in that example? I dont see any evidence of a changing external magnetic field. Also I wonder if it's a problem that there is also a magnet in the M5StickC case.

RE: M5StickC usb driver not working
@brain-brawn Have you tried installing the FTDI drivers (https://www.ftdichip.com/FTDrivers.htm)? I have found that this solved USB connection problems with obsolete versions of Windows in a couple cases.

RE: 5V input concern on M5StickC
@ajb2k3 Until Espressif changes their datasheet on the ESP32 this is officially not a 5V tolerant device. Many devices will work with it, but I will continue to test each one before telling people it is OK.

RE: live motion tracking with multiple m5stickc in unity [QUESTION]
Have you considered using Bluetooth? I have connected a single Bluetooth tracking device (not from M5) to Unity without too much trouble. I believe Bluetooth supports up 7 clients connected at once.

RE: M5stickC and VL53L1X sensor GROVE port
@cepics said in M5stickC and VL53L1X sensor GROVE port:
VL53L1X
I tried the VL53L0X unit on the grove port of the stick several times and could not get it to work. I know that really doesn't really help you but at least your are not alone in this quest :)

RE: Too into the stick?
@ajb2k3 That group was actually part of an order of 20. I am using them to teach a series of workshops called "Beyond the Arduino" http://tinkerfarm.net/workshops/m5stickc-workshop-2019/.
The idea is that you can learn basic Arduino using the sticks but then you can go much farther with the extra on board hardware or expansion via the grove port or header pins. Just finished the first one and I have learned getting people comfortable with the setup process--how to expand the Arduino IDE past the built in boards and libraries by itself expands their horizons on what is possible with micro controller platforms. -
Too into the stick?
Maybe you have too many of these things when you nave to buy a mass charger for them :)

M5StickC built in LED
Any insight on how the red led on pin 10 of the M5StickC is wired up?
I noticed that, using the Arduino IDE
pinMode(10, OUTPUT);
turns the LED on and subsequently
digitalWrite(10, HIGH);
turns it OFF, while
digitalWrite(10, LOW);
turns it ON again -
RE: All my sticks are defective...
For whatever its worth: I bought 3 to experiment with and they were all fine. I just tested 20 more that I bought for a class. 17 started up in the factory test program. The other 3 had no software installed but worked fine after I downloaded the factory test example.
