USB HID
-------------------------------------------------------------------------------

This is a set of example captures of USB/HID communication on an Olimex
STM32-H103 eval board with an ST STM32 (ARM Cortex-M3) microcontroller.

The firmware on the board is a simple libopencm3 example named 'usb_hid'
which lets the mouse curser move a small amount to the left and then back
to the right in an infinite loop.

Logic analyzer setup
--------------------

The logic analyzer used for capturing was a ChronoVu LA8:

  Probe       STM32-H103
  ----------------------
  6 (blue)    DM
  7 (yellow)  DP


olimex_stm32-h103_usb_hid.sr
----------------------------

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=100mhz --samples 8388608 \
             -p '7=DM,8=DP' -o <filename>
