Hi all - I am new to this forum and very new to the the Teensy. I appreciate any advice anyone might have as to how to solve this problem and thank you for your patience.
I am building a static Boeing 727 simulator using all OEM parts. One element of the instrumentation requires that I transduce a synchro/control transformer (which is AC based), which is basically a way to determine where a heading bug is set on the face of a 360 degree instrument face. In order to do that, I have a synchro to digital converter which takes the signal from the synchro and converts it to a 14 bit 'word' where each pin of the converter is 'on' when it is supplied with 5vdc. I need the Teensy to read all 14 pins of the synchro converter and using some math come up with the angle in degrees that the heading bug is set to.
I have done all of the other elements of this project using Teensy 4.1's, but am aware that the 4.1 is limited to 3.3vdc. So, I bought up a bunch of Teen$y 3.5's in order to accommodate the 5vdc.
Those arrived today and I was eager to try it out. Unfortunately the code (which I suspect is very very simple relative to what others are capable of in this group) would not compile and I keep getting 'Compilation error. Exit status 1'. I have tried muting each line of the code and then adding them back one at a time and the problem starts as soon as I send it any code. The code will compile and go to a Teensy 4.1 without a problem. I am using the most current Arduino IDE and I have tried loading Arduino IDE v 1.8.16 without any luck. Note also that I have the Flight Sim Controls plug in running and the appropriate line checked in the tools/USB tab.
Here is the code:
/* define the pins for the 14 separate input channels*/
int dpin1 = 23;
int dpin2 = 22;
int dpin3 = 21;
int dpin4 = 20;

int dpin10 = 14;
int dpin11 = 41;
int dpin12 = 40;
int dpin13 = 39;
int dpin14 = 38;

/* reset the work variable to 0 with each cycle of the loop*/
