Sensor calibration
I worked for about 12 hours on the project today. I had some help calibrating the gyros. We did this by setting the imu on a piece of rotating farm equipment and timing the revolutions to find the rate. This worked well for the pitch and roll gyros, but the yaw gyro has a problem. I might not be able to use it for the yaw rate controller.
I also made many refinements to the flight software. I corrected some errors and added more file outputs. I ran into a problem, though. There are so many outputs to a data file that the main loop isn’t fast enough to clear the IMU buffer at full speed anymore. I guess I’ve reached the upper limit of performance for the 386 computer.
Tomorrow I intend to install the system in the airplane. I doubt if it will fly tomorrow because I have too many other school things to do this weekend.
Next weekend is the very last chance I will get to fly the airplane.
