I'm trying to set up a setWatch equivalent for the ICM20948. Is there anyway I can use the function on a variable or a simple way I can set up an equivalent function to watch a variable?
This is on an MDBT42Q btw.
I'm not sure I understand the question... The ICM20948 is a 9 axis acceleration sensor?
Usually if you want to get a callback when there's movement from an accelerometer you configure the sensor so that it changes the state of its INT pin when the moment happens - then you just connect that wire to Espruino and setWatch on that.
Unfortunately, the PCB that I'm using doesn't have the INT pin connected to the MDBT42Q. That's why I'm trying to configure a software setWatch equivalent by watching the register or a variable. I hope that makes sense?
I just set up a small function to read every 50ms and calculate the euclidian distance with the previous value and it works fine. Thanks!
Ok, great! But yes - just to confirm - that's about the only thing you could do (read continuously and check the values).
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
