The Acceleration sensor MPU6886 has a pin that can be used get an interrupt on when a configurable threshold has been reached over a certain acceleration value.
My question is: is this pin connected to one of the ESP32 IO pins so it can be avoided to have a separate task running in this way. If the chip itself can do the work, then I guess it would be a good idea to use that capability.
Looking through the information of M5Atom-Matrix and M5Stack-Grey I cannot find any reference to this.
