Very nice simulator.
I've tested it with a MPU6050.

Re: paralel functions
You can read Multicore Support in this document, chapter 3.5 . import time, _thread, machine def task(n, delay): led = machine.Pin(25, machine.Pin.OUT) for i in range(n): led.high() time.sleep(delay) led.low() time.sleep(delay) print('done') _thread.start_new_thread(task, (10, 0.5))

Re: vehicle anti-theft device with movement detection - question
Can you look this topic Detection if device is moving (in motion) or not?
It sounds similar to me.

Re: Accessing hardware from native .mpy code
Can you give us the i2c device reference you're using?
For i2c you can start with this documentation.

Re: Detection if device is moving (in motion) or not
It's now time to apply standard score to MPU6050 gyro sensor to detect if we move. I reset cumulative gyro every 200 measures, it's because this method is not perfect, but to detect if we move it's acceptable. The same approach can be apply to acceleration sensor. # Created: 2021-12-19 11:06:43 # Li...

Re: Detection if device is moving (in motion) or not
When reading MPU6050's raw data, while the sensor is static on a table, we can observe a Gaussian distribution (blue histogram) . We can standardize those data using standard score (orange histogram) . This simple standardization will be sufficient to code a simple motion detector with a MPU6050. I'...

Re: Detection if device is moving (in motion) or not
...Sum those variations and you get the velocity... This is fine in physics textbooks. ... I agree with you Peter. I've been able to find, in my toolbox, a GY-521 MPU-6050 3-axis gyroscope and acceleration sensor. Here is a small test based on this excellent video . # Created: 2021-12-16 19:54:43 #...

Re: Detection if device is moving (in motion) or not
If you consider that your sensor is static when powered on and that you are doing one acceleration measure per second you get the velocity variation . Sum those variations and you get the velocity. from utime import sleep # Init velocity at power on velocity = 0 # m/s period = 1 # second def get_acc...

Re: Detection if device is moving (in motion) or not
Can you share with us, which 3-axis accelerometer and gyroscope sensor you are using?
