Happy Holidays and Thank you for looking.
I have a project that is driving a 7-segment led block just fine with a maxim 7219 display chip. I need to replace the 7-segment LED block with 7 individual LEDs and thought it would be an easy swap. LED segments are just individual LED's right? Well when I swap the 7 individual leds for the one segment block all the individual led's light up even if I display a blank with the 7219. What basic concept am I missing?
