cb846be507 fw/antorcha.c: add backward sweep 2012-06-25 11:37:16 -03:00
Werner Almesberger
00180fb287 try cleaner sweep synchronization algorithm 
The predictive part doesn't produce useful results so far, so we still
use a fixed offset from the trigger.

023c2aa1e9 fw/: base sweep start time on absolute time 
This way, we can define the next sweep while the previous one is still
in progress.

646f54d25c fw/sweep.c (TIMER1_OVF_vect): turn off the LEDs when done 
This means that the image no longer has to contain terminating all-zero rows.

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.

7816ea89d5 fw/antorcha.c: crude synchronization of image with movement 
Doesn't look too bad for a first try.

b262e2f142 fw/spi.c (spi_init): revert the SPI speed increase (caused instability) 
Some more testing showed that transfers would get stuck after ~40 packets.
Need to find out what happened before trying this again.

8eca4c99c7 fw/sample.c: fix logic in handler() and filter incomplete samples 
An incomplete sample would be an X value followed by another X value,
or Y followed by Y. Not entirely sure why this happens in the first
place, but it does happen.

2bac5e74a7 fw/image.c (image_first): call image_more to process the payload 
This makes things work also for zero-sized files. I.e.,

./antorcha /dev/null

does precisely what one would expect. (Before, the transfer was
accepted, but the first salt block became the new image.)

as if it was
