This week I removed the memory management from the signals processing code and changed the functions so they used passed in arrays that could be stored on the stack to prepare the code for integration. Theoretically code integration should have happened last week, but we did have an extra integration week and refinement week built into the schedule before Thanksgiving to allow for some flexibility. I also took one of our sensors to the roof of the East Campus parking garage and recorded data from it from a selection of distances while stationary and also while walking towards and away from the target car. Finally, I also spent a couple hours in the lab learning how difficult it is to solder very small LED contacts to connection wires. Things sped up significantly after I found some better solder, and I ended up making the two side rear groupings of three LED strips each. I also hotglued over the connections for those grouping and for the handlebar and brake light strip Emily soldered to protect the connections and provide support given the small contacts. Next week I plan to discuss with Emily my current plan for passing information to the handlebar LED controller. I’ve been told we have 7 bits to control the 3 sections we have with 4 states each so each section could be controlled by two bits, leaving to possibly be flipped to indicate a new object and flash the bar. I believe Jason is also ready to integrate the signals processing code so I want to walk through the simplified version of it that currently exists with him and make sure we have remained on the same page for the interface between our code and that something hasn’t been lost in translation.
