b33de16ac9 "fix" grounds by tracks into pour 
"finish" routing, ignore DRC violations from disconnected usb shield on
pin 6.

Add boot0 jumper pad "just in case" but really kinda dumb, we've got a
debug header on it. Why bother with this?

Change paper size in schema to get more space.

TODO: add silk?
TODO: replace "arduino" shape with just the pinpoints.

afb3081feb hw1: add crystal, more commentary 
probably need a crystal for usb :)

still needs footrints, will probably be any old 3225 part.

9c78e2ae40 hw1: begin routing. 
Spun the host, laid most signal tracks.
todo: vcc, ground pour, then shuffle all LA connectors for ease of
routing.

9994a66a3e hw1: schematic "finished" ?

8366c94592 common openocd: use -s to find files from test dirs. 
The sourcing of the common.cfg and the optional local files was failing
when invoked from a test directory.  Use -s and properly use [find ...]
to search paths nicely.

cb376f3959 WIP: hardware test partner round 1 
Not sure which kicad files are necessary and which are local yet!

Goal: fixed "host" board (this board) with socket for _any_ Nucleo64 st
board, giving access to test:
* DAC->ADC (both directions)
* I2C (both directions)
* SPI (both directions)
* Uart (both directions)

a socket for a cheap fx2 based logic analyser will be included, so that
sigrok can be used to capture tests of the actual line states.

c802ef055c rules.mk: make sure flashing works from other directories 
Provide full path when communicating with openocd.
This means you can run a permanent openocd session from the ./openocd
directory, and still have things working with just "make flash" from
whatever test directory you are in.

a2785bdf76 i2c-master: first hack working on f0 
read_i2c and write_i2c are not flexible enough, and terribly named.

future work to actually hook it up to a rs485 device.
