Minutes

  • @Titan Yuan

    • Pushed a clang format file to reformat/standardize code we have

    • Redoing channel calibration code

    • Integrated with the ADC; expecting to get ADC packets from SCuM soon

    • Noticed SCuM will crash with too much printf output. Lasts 1 to 1.5 mins at about 10 prints per second.

  • @Fil Maksimovic

    • Still developing plan to merge his multi-hop system with OpenWSN. Easier to add ipv6 to Fil’s system or to find bug in OpenWSN?

  • Discussion about PUFs to identify a serial number for lookup tables

    • LDO voltage has high variance, measure with ADC?

    • @Daniel Lovell's experiments with GPIO falling low/going high – maybe timing differences across chips are varied enough and stable enough to use?

  • @Sara Faour needs a random number generator. Bottom three bits of ADC may be a good source of entropy. Radio is also a great RNG!

  • @David Burnett

    • Admitting two students in IC design, MS student just started in open-source PDK work

    • Won USGS grant to design new low-power passive acoustic nodes

    • Paperwork with CMC Microsystems' cloud tools finished
