All,
Conscious original intent of DCI: Our application involves driving 76 discrete LEDs using a XC3S50. For cost reasons, we've decided to drive each LED statically (as opposed to scanning). Each IO is operating at LVDCI_33.
Can we use DCI to current limit (~430 ohm) the LEDs? It looks like LVDCI_33 is driver impedance controlled only, so the 3S50 will be a current source. VCCO is 3.3V.
Any comments / experience is appreciated.
