Hi,
on my machine, original firmdl3 took 45.2s to download firm0309.lgo.
- I increased packet size to 240 bytes, gaining roughly 2 seconds.
- Added packet size prediction and bytewise decoding with a state
machine
(The decoder spent 50 ms per packet waiting for a timeout.
1560 bytes / 240 bytes/packet = 65 packets, that's 3.25 seconds.
Timing is so tight now, I had to add an 1ms delay when switching
from reception to sending.)
New record at 41.13 s?
[mlnoga@mauve firmdl4]$ time ./firmdl3
