/**
 * Controls and reads actual measured distance from LCD bus of a Sndway SW-A40 laser distance meter.
 * Improved version not using Arduino delay that causes random problems with serial interface.
 *
 * Serial control characters:
 *
 * ?  Return identifier string.
 * c  Clears measurement results and turns off laser.
 *    Can be used as keep alive command to prevent auto power off after 150s.
 * M  Turns on device when off and triggers a measurement.

## main.c
/*
 * Creates sinus and cosinus lookup tables for IQ signal generation
 * for AD9361 (ADALM-Pluto) simulating TX channel settings.
 *
 * channel_convert_inverse Converts I or Q sample from host format into hardware format.
 * channel_convert         Converts I or Q sample from hardware format into host format.
