More I2C fun

2007-02-17 by djbrow54

Just for fun tonight I wired up a PCF8591 quad 8 bit A/D to my 
Ext I/O connector (I2C bus). I now have four additional A/D channels 
that are rock solid. I plan on using one for a potentiometer and 
another to a set of resistor dividers on a numeric keypad for menu 
input. That way I don't have to reuse any of the front panel controls 
for menu selection.

I was using one of the 16 input controls to select the number of 
sequencer steps, MIDI program change patch, and a MIDI note offset.  
Then I'd always have to reset that control for the sequencer value.  
This way I have dedicated menu controls and dedicated sequencer 
controls.

The group's been kind of quiet lately. Where is everyone?
