Timo Karppinen / Mbed OS Pmod_ACL2_ADXL362_L432KC_OS6_tk1

Accelerations in 3D with Analog Devices ADXL362. The PmodACL2 was used but should work with almost any sensor module with the ADXL362. The ADXL362 connects with SPI. The library ADXL362 published by Analog Devises includes the necessary methods for setting up the sensor and reading the acceleration results.

Dependencies:   ADXL362

+For the vibration detector code fragment, basically, 
+
+1. we use an inner-while loop for continuously getting xyz data from accelerometer, 
+we store two values in 10ms delay inside two different variables x1, x2, and compare their differences. 
+2. If the difference is bigger than a certain threshold( in our test,
+ our x, y difference thresholds are 7 and z is 20), it will break out this inner loop, 
+ and go to outer loop which controls the led to turn on 2s. 
+3. After each time the led turns on, counter will add one and will print how many knocks we have.
