=====Dragonfruit Team Meeting - March 6th, 2017=====
Attended: Kevin, Gordon, (Tyler)

==== Updates ====  
  * Finishing parts order for future boards
  * Verifying the major components of the schematic. 
  * Added decoupling capacitor to charging chip
  * Added voltage divider to VBATT connection between charging chip and MCU. (Avoid direct voltage connection)
  * Started the board design of the PCB design.
==== Problems ==== 

==== Tasks ====    
  * Debug populated board 5
    * Some parts need to be swapped out
    * Continuity test of board 5
  * Create another spot on csv file for measuring voltage at XBee pin 
    * Will be used to look for ghost voltage
    * Nathan said we might not be able to do it : Correction we might be able to use it
    * Debug LED flag : turn on led and keep it on after Ghost voltage is perceived 
    * ADC6 might be able be a input chart
  * Look into power switching of charging chip
    * Tryston said that between 4.3 - 4.5V the board would be powered by the battery instead of the solar panel
  * Use debug LEDs to set a flag if the board is not transmitting 
    * What do we flag?
    * Make the XBee drop a packet using the light
    * match XBee power drop to switch between solar panel and battery power
    * Look into board behavior when light is on full blast
  * Populate a new board as soon as new parts come in
  * Take off vswitch and connect to the charging chip load
    * LEDs should act the same as the adafruit charging chip LEDs
  * Populate a board with charging chip 
  * ** The VBATT connection is directly connected to the MCU **
    * Incorporate a voltage divider to that connection.
  * Add decoupling capacitor to the vswitch connection (may or may not matter)
  * Charging chip debug LED tests
    * 1 - 5bit number to voltage tests
      * this is used to make sure that the charging chip follows tryston's charging chip behaviors
      * to be completed for adafruit charging chip and dragon fruit charging chip
      * 5bits = 31 in decimal
      * 0 = 3V
      * 9 = 3.9V
      * 13 = 4.3V
      * 20 = 5V
    * 2 - Use 3 debug LEDs to visually indicate when switching between solar panel and battery
      * LED 1 : Vload = Solar Panel 
      * LED 2 : 4.3 < Vload < 4.5   (around the voltage that Vload switches from Panel to Battery power)
      * LED 3 : Vload = battery mV
      * If all are off, then the load voltage is between 4.3V and battery voltage
      * Need to connect Vload to MCU
    * 3 - Use LEDs to flag Ghost voltage, low XBee voltage, and dropped transmission
      * LED 1 : Ghost voltage is 4V (this is much too high for XBee power)
      * LED 2 : XBee voltage at less than 2.7V (full range is 2.7 - 3.6V)
      * LED 3 : flag for transmission (we do not know how to do it yet)
      * Need to connect XBee power to MCU
