Notes

• Titan@berkeley

  • presents his way of calibrating the LC, sweeping from [0,0,0] to [31,31,31]

  • sweeping takes 20min

  • discussion about clock noise, using optical SFD and RFTimer

  • this week:

    • get cal monotonic

    • use OpenMote as frequency reference to sweep against it

• Jove@berkeley

  • optical programmer

  • successful using laser

  • laser shines a line

  • next week:

    • check optical cal, as programming isn't a guarantee that cal works

• Ahad

  • current consumption

  • looking at problem on Q9 dev board (all should work except for UART, although Lydia indicates there may be larger problem, Ahad confirms GPIOs work)

  • Thomas asks to take a pic of setup and add to slide

  • 310 uA of current after programming, with ASC all to 0

• Thomas & Tenfei

  • EWSN paper

    • Thomas presents RC of the paper

    • Lydia agrees to do a quick review

  • code review

    • Thomas proposes to do the following PRs:

      • same code with indentation

      • same code with comments

      • replacing magic values by #define statements

    • Lydia would be primary reviewer of PR from Paris

    • discussion about simple tests to verify non-regression:

    • 15.4 communication between SCUM and OpenMote

    • verify ldo control functionality

    • verify simple GPIO

  • admin

    • crystalfree.org bought

    • Thomas to set up www/pad/meet.crystalfree.org

    • Lydia to buy webcam
