Re: Detection if device is moving (in motion) or not

Now everything is awesome! Thanks for the new driver, Olivier, and for asyncio comments, Peter. This attached code seems to work in asyncio, I have not modified the class at all, and I am OK with initial calibration which does not have to run concurrently with other code. As I restart my micro-contr...

Re: Detection if device is moving (in motion) or not

Hi Olivier, your approach looks very promising indeed, but I have colossal problems rewriting it for asyncio :cry: Are you able to give any hints how to make it async-able? My current code never shows "you move" :( async def gyro_raw(): #Read and unpack gyro raw data r = await unpack('>hhh', i2c.re...

Re: Detection if device is moving (in motion) or

The only problem is, that it still takes 3-5 min for the GPS to fix its position. But I guess there is no way around if I don’t want to let the GPS run all the time. And there is no way to do this without draining the battery to much when the car is parked… I'm making a similar project and I decide...

vehicle anti-theft device with movement detection - question

Hi, don't have a clear idea how to design a correct algorithm for detection movement, counting the fact we have very limited resources on microcontrollers. I plan to use MPU-6050 sensor but the question is more general and does not depend on sensor. Main issue is that I want to observe a trend, not ...
