Averaging loop only iterates over 30 elements, but divides by 32.

[zenith-parsec]

The average_signal_pulse is calculated incorrectly in the detectInput() function. The number of elements added by the loop is 30, but sum of those 30 elements is divided by 32.

The loop is here:

AM32/Src/signal.c

Line 241 in 97f0d66

for (int j = 1; j < 31; j++) {

and the division is here:

AM32/Src/signal.c

Line 250 in 97f0d66

average_signal_pulse = average_signal_pulse / 32;

The fix is to change either the range being sampled (did you mean to say

for(int j = 0; j < 32; j++) {

instead?) or change the value it is dividing by (to 30).
