We are just finalizing schematics.
I sent Harry some crude pencil drawings of a starting point.
He is going to massage them to his liking.
Current plan is to support 8 in and 8 outs, both 10 volt and 5 volt ranges with different
resistors.
Unipolar output for simplicity and accuracy.
The only change I see is to move the start PB to IRQ1 input (which is now AUX). That would
allow using an interupt service routine for the start PB.
The old start pin gets used for DAC select to select between the two quad DAC chips.
That still leaves the I2C port uncommited. Does anyone have a neat I2C port expanded they
would like to mention?
Thank you.
