4c905300d3 Minor CNTR layout cleanup. 
- cntr.brd: added pin 1 marker for U1
- cntr.brd: moved via next to P7 a 5 mil away from the probe trace
- cntr.pro: commit noise

f2ab3cfd18 Updated cntr.sch for BOM processing. Fixed omission in atrf.sub 
- cntr/cntr.sch (P5, P6, P7): added footprint
- cntr/cntr.pro: commit noise
- bom/atrf.sub: accept resistor values without unit or multiplier (e.g.,
  "68" becomes "68R")

2ad54bf2e2 Cleaned up board outline and ground routing. 
- cntr/cntr.pro, cntr/cntr.brd: reduced PCB edge line width from 15 mil to
   5 mil
- cntr/cntr.brd: make edge follow hole for MMCX connector
- cntr/cntr.brd: fill bottom and input area with ground
- cntr/cntr.sch, cntr/cntr.brd (R4): replace 0 Ohm jumper and GND via
  P2.1 with vias

e9147b0ba9 Major redesign of "cntr" circuit. 
- cntr/cntr.pro: added usb_a_plug.lib, mmcx-f-edge.mod, usb_a_plug_smt.mod,
  and sot-323.mod
- cntr/cntr.sch, cntr/cntr.brd: reassigned LED and pull GPIO for easier
  routing
- cntr/cntr.sch, cntr/cntr.brd: replaced mini-USB receptacle with USB A
  plug and removed 0 Ohm resistor previously used for swapping D+/D-
- cntr/cntr.sch, cntr/cntr.brd: changed TVSs on USB from 200 pF 0603 to
  100 pF 0402 type
- cntr/cntr.sch, cntr/cntr.brd: replaced basically unterminated 100 mil
  header with properly terminated MMCX connector
- cntr/cntr.brd: reduced board width (nominally 15.8 mm) to USB connector
  width (16 mm)
- modules/mmcx-f-edge.fpd: swap contacts for compatibility with "BNC"
  symbol

a2e91cf13e Take "pads" and "stdpass" modules from kicad-libs and remove local copy. 
- atrf/wpan-atrf.pro, atusd/atusd.pro, cntr/cntr.pro: use "pads" footprint
  from kicad-libs
- atrf/wpan-atrf.pro, cntr/cntr.pro: use "stdpass" footprint from
  kicad-libs
- AUTHORS, modules/INFO, modules/pads.fpd, modules/stdpass.fpd: removed
  pads.fpd and stdpass.fpd

81ab679fbd The parasitic capacitance of the three probe input pins and R1 formed a 
quite formidable low-pass filter that almost completely eliminated the
1 MHz signal.

- cntr/cntr.sch, cntr/cntr.brd: changed R1 from 100k to 1k to increase
  input bandwidth

51de2a5235 Forgot cntr/Makefile. Added ground fill. 
- cntr/Makefile: oops, forgot to add this one to the repository
- cntr/cntr.brd: fill unused spaces with ground

5553d3e75b New circuit: an arbitrary-precision counter. 
- BOOKSHELF: added the C8051F320 (alias "f320")
- BOOKSHELF: added "atrf" alias for AT86RF230
- BOOKSHELF: added "f326" alias for C8051F326
- AUTHORS, components/INFO, components/c8051f320.lib,
  components/c8051f320.dcm: added Silabs C8051F320
- AUTHORS, modules/INFO, modules/Makefile, modules/qfp.fpd: added LQFP32
  for C8051F320
- cntr/cntr.pro, cntr/cntr.sch, cntr/cntr.brd: arbitrary-precision counter
