All Rights Reserved.* $Revision: 1.3** This S-function block sends values to the instruments from the computer to* the PhEagle flight sim cab. This is the a basic version of the outputs* to the Sim cab sending out only the altitude, airspeed, attitude, direction* g’s, angle of attack, side slip, L-rpm, R-rpm, Vertical speed, and the* forces back to the sim cab stick. The stick positions are read in the* stick block - ph_stick.c*****************************************************************************/#define S_FUNCTION_NAME ph_inst#define S_FUNCTION_LEVEL 2#include "simstruc.h"#include #include #include #include #include #include #include #include "cyda.h"char errorChecking;float pi = 3.14159;struct DAC d16, d12;struct DACChannelaltimeter,pitch8Ball,124
