Sunday
- Worked on design review report
Monday
- Worked on the design review report.
- Further refined the testing procedures. Interestingly one of the things brought up during the design review presentation will help a lot with testing. The fact that the speedometer will be connected to the Pi via an Arduino will enable easier testing because bicycle speed can be simulated simply by programming the Arduino to report a certain speed.
- Noticed from looking at vehicle system testing procedures that generally very few tests are carried out. The primary metric is the time and distance at which the warnings go off, and whether warnings persist all the way through the danger. So the test were designed similarly to have the main metric for a successful test be the time-to-impact when the warning goes off and the persistence of the warning.
Wednesday
- Started working on the Bluetooth interfaces between the Pi and the rest of the system. Worked on hashing out the communication needs and protocol between the Pi and the Arduino on the jacket.
- Realised the communication needs between the Pi and the jacket are not very significant, and some communication requires guaranteed transmission while some communication just needs to get to the jacket quickly and can just be constantly transmitting. Will be interesting to see how the Bluetooth can be utilized for this.
Saturday
- Starting working on the LKM for the Pi. Need to get interrupts going for the ultrasonic sensors.
