Re: [mh] Question on xPL-perl

[George C. <ge...@fe...>]

Hi Lieven,

Great!   Thanks.  I guess I'm very unlucky, as I tried a 2nd time as
well with mharduino ... another 9 character name.

I really appreciate you taking the time to look at this.  I was
beginning to question my sanity.  I (obviously) never gave a thought to
the length of the name.

I'll get on putting this together over the next few days.  I've still
been ruminating a bit on it but I figure eventually I'll implement:

 - A status command which will return all of the current pin states
 - A trigger event that states the board has been initialized, and needs
configuration
 - Digital pins: Trigger events - returning on/off whenever it changes
 - Analog pins: Trigger event when threshold passed, up or down, with
some hysteresis
 -  Or if no threshold set,  then send a trigger when value changes by
some amount

For now I'll just configure it in the xpl-perl driver.  But accepting
xpl config commands might be better:

 -  set each pin as:  input,  input w/ pull-up,  output or analog output
(PCM)
 -  set an initial or "normal" state for each digital pin.
 -  set a trigger level for an analog input pin.

And I still need to think a bit more,  but I'm wondering if there should
be an ACK / resend function of some sort.  Considering that UDP is
unreliable, it might make sense to repeat a status message.
 
Thanks again,
George
