Week 2 (13th Feb 2015)

This is the second week of our weather station project. The main progress during this week include:

On Monday, we contacted our professor and realized function of letting the LPC1768 talk to XBee.

As for the following three days, we continued with testing to let FDRM-KL46Z talk to XBee. During this process, we met several difficulties in finding corresponding and efficient pins which should be wired together. We three group members got to know about software of X-CTU which is a quite useful application designed to enable developers to interact with Digi RF modules through a simple-to-use graphical interface. Moreover, what worth to be mentioned was that the reference book that we referred to is 

Building Wireless Sensor Networks: with ZigBee, XBee, Arduino, and Processing

Considering the following task of achieving data sending and receiving between FDRM-KL46Z and LPC1768 by XBees, it seems essential to consult that book as well.

On the lab day, we started with programming the overall code. Having tested several example codes, group members got command of method of displaying on the LPC1768.

In order to write the main part of the code, we planned to connect the outdoor wind and rain gauge sensor together with the FDRM-KL46Z. What we needed are 2 sockets with which the sensor can be plugged onto the breadboard.

To sum up, during this week, we mainly focused on testing and learning. Although the visible programming progress is limited, we have the confidence and determination that in the following weeks, we will be more active and efficient in the designing project.
