One thing about the DTH series is their low sample rate (around 1Hz). It is very possible you overwhelm the sensor by requesting values too frequently. Another thing would be to encapsulate the measures within a try: except: block and manage the errors...

I think the problem is in the to_bytes() method because if I remove it the error is not showing but the program is not functional. Any ideas on this ? You are missing the parameter specifying endianness. One should write: a=12345 print(a.to_bytes(2,'big')) print(a.to_bytes(2,'little')) and that eve...

Just to be sure: have you tried running your M5Stack using a USB charger instead of your computer? Apart from resetting the WDT, is there something else hapening in your code? The reset could very well be caused by a brown-out due to excessive current consumption. I had that on an ESP8266 connected ...

That's the weird bit: normally the bno's address should be 0x28 or 0x29, depending on the state of its COM3 pin. If you are using the adafruit package, this pin is accessed through the ADR pin and defaults to COM3 low and 0x28 as the I2C address. So first things first: check if your bno is properly ...

Weird. The scan should consistently show 40 (or 41) not a mix of 40, 41 and none of the others.

What addresses do you see? The bno055 chip should answer 0x28 or 0x29, and the SSD1306 0x3c or 0x3d

Excluding the UNIX port, I am not quite sure that one can get such a figure. In many cases micropython is running on bare metal without any os, so the "load" would be 100%...

You could use picoweb to implement a very simple web server on your microcontroller.

Can I run specify .py file (e.g aaa.py store on Micropython board , not boot.py or main.py .) via REPL prompt after boot done?

shoud do the trick. note: no .py extension, just the file (module) name...

Not as such. However there are alternatives on the ESP32: uasyncio , but that might cause you to completely rewrite your scripts use lightweight threads with the _thread module. It is documented for the lobo port . However, I cannot find documentation for the mainline (apart form the fact that it is...
