Need documentation for TlcMux #1

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I'm trying to understand how to wire up a multiplexed display using the
TlcMux version of the library.

From reading the code, I think I've got it -- it looks like your code
running in the Arduino loop() needs to call TlcMux_shiftRow() with the new
row number while also changing the row select via hardware (turning off one
transistor, turning on another).

Is there some way to automate this?  What about using the timer interrupt
to automatically call a "row change" routine?  I've not yet worked enough
with the timers to know if that's possible, but it seems triggering row
change on BLANK transition would work nicely.

Thanks!

I love the diagram used at

close.png. If I could get something similar for the MUX libraries I would be 
extremely grateful.
