You know, this scope is quite affordable. But no, I've just borrowed
it for now.
I did manage to interface the AtomPro24 I2C to a SAA1064 I2C to 7
segment LED driver. I am sending 6 data bytes in a single message (7
bytes total since it includes the device address byte) in 1.32 mS.
The receiver is correctly ack'ing the packets and I am not getting any
AtomPro24 errors.
With interrupts enabled at 1 mS timer, I can see the packets jitter as
the cycles are stretched by the interrupt service routine. It all
seems to work quite well (as long as you used a scope to figure out
the peculiarities of the i2cout command).
The burst data transfer is 4545 bytes/second. Now that I have a known
data stream, I will see if I can get an AVR to correctly receive it.
I'm not going to do anything until my LCD arrives and I can verify
functionality of my code. I don't want to tear the development system
down yet. The LCD is scheduled to arrive Monday.
