 Finished working on Lab 2. Excersises definitely helped me remember verilog from my classes, and I'm feeling much more confident with it now. Still couldn't figure out how to test my code aaas described at the beginning of the lab 2 description, but I compared my work to other members' Lab 2's to make sure I was doing everything correctly.

+Week 4:
+Started Lab 3: https://github.com/Noahms12/onboarding-lab-3.git
+
+Got through exercise 1, and started exercise 2. I haven't combined c++ with verilog before in this way, so understanding how things like the uint16_t data type work, and how I can manipulate it is difficult. I've looked at a few completed design notebooks to get some ideas, but out of the ones i've found, there's a lot of syntax that I'm not familiar with.

+Also attended the meeting on thursday to try to figure out the problem last week with testing my code, but was unable to find an immediate solution.
