Ryan Ludt Week #10

This past week was a very very busy week. We were pretty much completely stuck on the image processing part of the project using Xamarin and C#, and the documentation online was just absolutely horrible. So we decided that we were going to completely restart what we had and rewrite the application in Swift for iPhone. Ethan stayed up super late one night and got a functioning light detector working on the iPhone in Swift.

We then worked through the weekend and were able to get our app fully functional in Swift! Besides a few bugs here and there, we now have a functional application.

We worked on the image processing portion a lot and were able to determine when the flashlight of the sending device was on and off while sending a Morse code message. I worked on the compression of that binary string we brought in of 1's and 0's in order to compare the Morse code units to our English word chart to actually convert the Morse code message back to English on the Receiving device. This consisted of looking at how many frames the camera was reading that a single morse code unit was on/off. Once we found a consistency in values for each dot and dash, I created a range of frames that converted the long binary string into the shorter binary string we originally sent from the sending device.

Once we had this correct binary string converted to a binary sequence we could compare to our letter chart, we were able to display the message on a label on the receiving device, one word at a time. We are hoping to try to get it down to one letter at a time before the final presentation.
