First thanks to all that have provided documentation, examples, and many answers.   I am a bit overwhelmed
 with all the information you guys have provided.

Over the years I have used the BS2 for several fairly simple projects- with success thanks to a great product.

Now I'm switching over to SX family primarily the 28 using the BASIC compiler, simply because its faster and cheaper.

My first SX28 project completed is a battery monitor/controller that used the example clock/timer to display total usage and timed periods.
I used an ADC0831 to monitor battery voltage and  low voltage dropout,  HIGH and LOW commands to clock and read data from the AD.
(And yes the code is clunky, but hey it works)

Problem statement:   I want to use multiple SX-28 chips on different boards and use the modified clock/timer code with interrupt 
for both time display (whole minutes) and to display voltage/status readings from other data collection boards.  ( Seven segment data w/6 displays.)
I plan to use a 4Mhz resonator on each processor.

 Question:  Since the I2C is synchronous does it provide a workaround for the timing issues associated with serial data transmission and  interrups?  Iwould plan to
use Clock/Display board as the master.

Many Thanks to All,
jon duke
