Last week I fixed my MATLAB code that doesn’t use forces. I found that our ground speed will have a great effect on the lead distance than the altitude. Several figures are below from the script.
Altitude varying slope: 0.492
Ground Speed varying slope: 3.67
Varying ground speed has a larger impact on the lead distance.
I started writing the code for the microcontroller and found that I have to use a serial peripheral interface (SPI) technique. Since I am not familiar with SPI, I have been doing some reading and checking examples online.
Ervin and I also connected the test bed set up to an oscilloscope. We were able to measure voltage of the battery, however, this does not tell us much without the current.
My goals for this week are to interface the microcontroller and air speed sensor using SPI and include forces in the MATLAB script.
