Werner Almesberger 695bc5a25a fw/: reduce image width from 100 to 80 square pixels
To achieve square 100 pixels (1:6.25 image aspect ratio), very vigorous
movement is needed. 80 pixels (still 1:5) are easier. Initial estimates
suggested a usable range of 1:4-1:5, so this is still good.

Note that we may want to change the aspect ratio of the pixels themselves
in the future (for smoother letters), so the pixel count may go up again.

80 pixels correspond to 11 characters in a 7x5 font with 2 pixels
separation between characters. We may want to go up to 82 pixels
to allow a 12th character - or use a proportional font.

Antorcha - A LED-based signal device
====================================

...


Directory placement
-------------------

Antorcha makes extensive use of libraries and header of the ben-wpan
project. For this, the top-level directory of the ben-wpan project must
be in the same directory as the top-level directory of Antorcha. E.g.,

/home/qi/ben-wpan/
/home/qi/antorcha/


/etc/avrdude.conf entry
-----------------------

Antorcha uses the atusb programming adapter from the ben-wpan project.
Since the pin positions of MISO and MOSI are swapped between ATmega32U2
and the ATmega168, the following entry is needed in avrdude.conf (which
is the same as the entry for nanonote_atusb except that the pin numbers
for mosi and miso are swapped):

programmer
  id	= "nanonote_antorcha";
  desc	= "NanoNote 8:10 card adapter for ATUSB";
  type	= nanonote;
  reset	= 1;
  sck	= 8;
  mosi	= 6;
  miso	= 7;
  pgmled = 2;
;
