Here below the second part of the algorithm describing the basic PEDOMETER. The picture here below shows the second and last part of the related FSM code: it is dedicated to recognize when the debouncing phase is over (n INCR command), and to count the further steps until the algorithm resets. In attachment you can find the state machine code to upload on your Unico tool.
Input data are the axl output stream (select ODR >= 26Hz)
Masks selects as interesting orientation the overall resultant v+ (MASK_C=0x02),
Thresholds are set to 1.1g (TH1) and 1.2g (TH2)
Timeout have been selected and tuned as 3sec (short counter, TI3) and 0xFFFF (long counter, T4)
Output of this section of the code is when a step and a debounce phase steps are detected
This is the last technical poos about FSM, so... Enjoy it!
