Low Cost AOUT port using the IIC circuit.


Recommended Posts

I was thinking that the resistor ladder from the AOUTLC could be added to the unused port A (you would loose the LEDs) of the 16F88 and possibly create an AOUT port on the IIC circuit.  This would give you MIDI in/out and AOUT in one low cost module.  The only snag that I could see is that I think the A4 pin can only sink and not source.  Any thoughts on this, anyone?  BTW TK, I have my MIDIbox SEQ running V3.1 with the AOUT module, 4 IIC ports, and 4 gates.  It works amazing!  The adventure now begins to find all of the capabilities that you have hidden is this state of the art machine!

Hi Tim,

it's a nice idea, but I think that controlling an AOUT_LC module from the core works much faster than accessing a IIC slave. The only advantage I see is, that it sidesteps the IO pin limitation of the core module.

Best Regards, Thorsten.
