probably doesn't work like that but that's for later.

improve stats reporting
...
now again use three messages to transmit stats (much more efficient than
sending single values, also more acurate).

...
- led_signal: blink 8 status bits (short=0, long=1)
- led_activity: blink for a short period after a trigger, e.g. for network
activity

com2w: added some recovery code, improved protocol.
...
after sending a byte wait for the same time when sending the last bit as
with the other bits (otherwise the last bit might get lost by slower
devices).
2025-08-20 23:27:17 +02:00

avr: improved timing for sending bytes via com2w interface.
...
Still quite different among devices but that's just prove that the protocol
works without prior synchronisation.

avr: started working on new SPI-like COM protocol.
...
use a clock and a data line to introduce synchronisation into the
protocol to be able to work with the wide range of mcu speeds (no need for
exact timing, no need for exact calibration).
2025-07-19 09:42:02 +02:00
Martin Preuss
