This week I create a brand off the GitHub Jason created for code management to develop the basic code for signals processing. I spent a fair amount of my time this week considering how to implement storage of historical data that might need to be kept for filtering and settled upon a linked list to allow easy ordering step through. For our purposes a list will also work better that a double array as we won’t have to rewrite in the data to shift its relative time position. The list is doubly linked to allow for O(1) removal of old data as I believe time will be more of a concern that storage for us. The list and helper functions have been implemented but not robustly tested yet as I am refamiliarizing myself with C code. I have also have written the code to calculate multiple target distances from the data, my code for this portion is based off the code the manufacturer had provided to preform such a task. I plan to try to have a version of the speed filtering code that will have some changeable constant (concerning what speeds to filter out at what distances/should we show things with negative velocity if they are very close or allow minor negative velocities to account for error) done before class on Monday and plan to get some opinions from my teammates about how to set these constants which I will use as benchmarks about whether or not to display data.
