- NTP is working to time.srv.ualberta.ca. Google communication is working. I did extensive testing with various combinations of parts and in the end, I determined that the difference must be due to our wiring vs. Kienan and Dave's PCB. The only real difference between the two was the presence of 2x 0.1uF capacitors on the 3.3V lines; I assumed they were for other parts and wouldn't make a difference - but I was wrong! It looks like adding the capacitors gets the Wiznet working.
- In terms of code, we just need to tie everything together and get it working in flash (and also modularize the code a bit and make it nicer).
- Tomorrow (or rather, later today...), I need to ask Nancy about using 3.3V to switch a 5V signal. The speaker is not loud enough (and is a tad unstable), but we get both loudness and stability if we use 5V to pass the signal.
- I'd also like to see if I can get a battery switchover circuit working. This isn't too important, so I shouldn't spend more than an hour on it. There is some information available here.
- We should also get the NVRAM hooked up.
- I'd also like to see about getting some heat shrink so that the weight sensor cables don't get tangled up so easily.
