This week I got the timer interrupt to send the node into standby mode. I also figured out how to change the timer’s period after it is initialized, so that the same timer can be reused with a different period. I was able to have a timer wait a short time before triggering an interrupt to take a temperature sensor, then changed the period so that it waited a longer period of time before putting the node into standby mode. I also made an external reset button and got a 9V barrel jack so that we can power a bunch of nodes without having to plug them into our laptops and can easily reset them all at the same time with a button. This has made it easier to test with more than a couple nodes. I have also been helping my group prepare for the interim demo this week by helping Arden with testing the STP, and I plan to help him test and debug the LSA this upcoming week.
