Polling vs interrupts in a chess clock.

Polling
01/01/70 00:00
Debounce
01/01/70 00:00
Either
01/01/70 00:00
debounce?
01/01/70 00:00
Yes
01/01/70 00:00
Alternatively
01/01/70 00:00
but PBs update clocks asynchronously
01/01/70 00:00
micro time vs real time
01/01/70 00:00
One second is a long time in Blitz chess
01/01/70 00:00
Use a fast main loop
01/01/70 00:00
but this won't let us power-down
01/01/70 00:00
Do what Ian says
01/01/70 00:00
I don't understand
01/01/70 00:00
set a flag in the PB ISR right?
01/01/70 00:00
No pb isr as such.
01/01/70 00:00
The PB INTs wake up the cpu also

Still LCD

Isn't PB bouncing going to be a problem?
01/01/70 00:00
No
01/01/70 00:00
OK, I get it now, thanks
01/01/70 00:00
In the timer loop
01/01/70 00:00
Is it?
01/01/70 00:00
No
01/01/70 00:00
ISR capability?
01/01/70 00:00
Pick a way
01/01/70 00:00
ISR reources
01/01/70 00:00
Debounce
01/01/70 00:00
Define Immediately
01/01/70 00:00
No if the debounce is post delay
01/01/70 00:00
Granted
01/01/70 00:00
naah and to the question bu the OP
01/01/70 00:00

Re Re the smartest thing
01/01/70 00:00
as for the character LCD ...
01/01/70 00:00
There are several IC to do this
01/01/70 00:00
Perhaps it's cheaper ...
01/01/70 00:00
DigiKey has them
01/01/70 00:00
