====== Verification Team Meeting - December 4, 2015 ======

Attended: May Chen, Kristie Lee, Jon Liang

=====Notes about Verification Board=====
  * How to select an SD card reader?
    * Will be connected from MCU → SD card w/ hub
    * Uneven solder pad layout can be made uniform approximately, as long as contact is made
    * Look at number of positions and match it with SD card being used
    * Look at datasheet to see what each pin does
      * Power, ground
      * Data pins
      * Receive, transmit, other communication
  * Does it need supporting parts?
     * Resistors, capacitors, clock?
  * Software
    * How does it communicate?
    * What pin to connect on the MCU to SD card reader to store data, etc.
    * Receive, transmit, gnd, pwr, other communication
  * Leave unused pins open
 
  * Programmer
    * Ask Dragonfruit/Cranberry how their MCU gets programmed?
      * We will use the same circuit and program it the same way b/c same MCU
    * Ask Apple what is on the receiving end of the Arduino (silver usb programmer thing)
      * Put that on our board
    * Look at schematic/datasheet of Arduino to see how its usb programmer connects to the MCU
      * Match the pins to our programmer
    * Same programmer can be used to program apple and program our chip
  * We’re basically making a "baby Arduino"

  * Communication system
  * VB send request to Apple
  * Apple send request to sensors
  * Then repeat backwards
  * Atmega has back and forth communication with sd card, not one way

  * Power system
    * Use terminal block
       * One to connect to power supply wires
       * One to mount on our board
    * Power with power supply, not battery b/c for bench testing
    * Switch
      * Ask Dragonfruit what kind switch they’re using
    * Voltage regulator
      * Need 5V and 3.3V? 
      * Cascading: pass through switch, connect highest voltage signals, then go down lower
         * Eg. switch.. 10v reg… component that needs 10v… 5v reg… component that needs 5v… 3.3v reg… etc.
    * How are we powering Apple?

=====Tasks=====
  * Find parts for SD card reader, programmer, and switch
  * Look at Arduino datasheet
  * Talk to Apple, Cranberry, Dragonfruit about parts

=====Completed=====
  * Poster ready to be reviewed by Kenny/Christie
