Worked on Bare Guava, we figured out the issue with pinout difference between Atmega 1284P (Through-hole) vs. Atmega 1284-au (Surface Mount). We follow the pinout name instead of pinout number, which should be the same, we figured out that the reason why Atmega 1284-au has 4 more pins than Atmega 1284P is there are 2 more pairs of Vcc and GND.

We will focus on figuring out how to bootload and program the bare Guava, figure out the Xbee issue with REV C, do the voltage test on REV CIV, figure out how to bootload REV CIV, and assemble another REV CIV in case of burning the current one.

Worked on Xbee communication for REV C, figured out that it only sends a package when the reset button is pressed. This issue could be caused in multiple areas like programming error or schematic error or PCB trace error.

Worked on bootload bare Guava, was able to find a Youtube video that shows how to use Arduino Uno, https://www.youtube.com/watch?v=dpgcBsl9D4k. Although we successfully boot-loaded the Atmega 1284P, this boot-load might not be correct because there wasn't an option to bootload with 8 Mhz.

Next meeting, we will be focusing on using ATOM to program our bare Guava because we couldn't find a way to program Atmega 1284P with Arduino IDE.
