Hi @gewe, what do you want to build?

Maybe consider using Arduino as I had no troubles reading out the SHT30 on my PM2.5 with that.

I am sure you found it yourself already but just for reference: https://github.com/m5stack/M5Unified

Cheers

Maybe porting your code to M5Unified would make sense then

Thanks @teastain for the hint with USB CDC on Boot!

I forgot to mention that I am on PlatformIO but the snippet shown below added to the platform.ini file helped me to solve the problem. Previously I didn't had to specify any build_flags to see the Serial output, so maybe this is a change introduced by PlatformIO.

monitor_speed = 115200
build_flags = 
	-D ARDUINO_USB_MODE=1
	-D ARDUINO_USB_CDC_ON_BOOT=1

Hi,

I am using M5Unified on my AtomS3 but can't get Serial.println("hello") to show up on the host. I configured the baud rate correctly and things worked on a previous project without M5Unified on an AtomLite. I guess I am missing something obvious here.

Any help welcomed.

Marc

Alternatively - using M5Unified you can also call:

M5.Display.sleep();

To wake it up again use:

M5.Display.wakeup();

@ajb2k3 - exactly, it is the SMT32 based hub.
Thanks for sharing your experience - good to be not alone...

Thanks @felmue ,

I tried this in various variations - in setup - in the for loop - with and without delays - but with no effect whatsoever.

My guess is that this is an issue with the Firmware on the v1.1 version - maybe someone from M5Stack Support can confirm?

Hi @felmue ,

I am using the example you refer to but it does not work for me. I.e. any LED Unit I connect (or also the FADER Unit) - always only the first Lamp shows up.
Seems the V1.1 has an issue then and I have to buy the old Pb.Hub.. :-(.

Hi @gavin67890 ,

I am using Arduino.

Has anyone succeeded in driving all 3 LEDs in an RGB Unit from a Pb.Hub(v1.1)?
I only ever manage to set the first LED of the RGB Unit but never the other 2. Is there a known issue in the Pb.Hub firmware?

Take a look at the data-sheet: https://www.st.com/resource/en/datasheet/vl53l0x.pdf

Table 13 shows the dependency between time budget (20ms to 200ms) for ranging and resulting accuracy.

Hi,

FYI, I built this little robot using M5Stack components like ATOM Motion, Servo Kit 360, ToF HAT and others.

See the project description here:

Really great how M5Stack components can be combined and used together with LEGO parts.

— Best regards

Hi Paul,

I do this on my Atom Lite:

#include <FastLED.h>

CRGB mainLED;

void setup() {
  M5.begin();

  FastLED.addLeds<NEOPIXEL, 27>(&mainLED, 1);
  FastLED.setBrightness(10);
}

And then in loop to set the color I use:

      mainLED = CRGB::Red;
      FastLED.show();

Hope that is of any help.

Hi,

this PlatformIO project turns your M5StickC into a laser rangefinder.

For this you need to attach the ToF HAT to your M5StickC.

Happy range-finding!
