moving Q15 trig functions to Q15 retval
progress
configuration update
transmitResults takes uin16_t flags, not uint8_t
better rounding for trig; 16bit trig uses 24bit LUT for rounding
mostly uin16_t, not uint8_t variables for FIR.c
explicit casts from int16_t to uint8_t
include timerDrv.h, not timer.h in timerDrv.c
improvements for trig LUTs
oops, -0h7fffff00 == -2147483392, not 214748339
