Hi,Ishikawa said:So I need 4 inputs to drive the 8 leds.
From the picture there is 5 wires:
One for the first led always on
One for Ground
The other 3 for the 8 leds (remember the 8 leds r actually considered to be 15)
However from the equation above, 3 inputs drive only 6 leds and there 8 left.
I'm I wrong???
Thanks
Are you sure that the first LED is always on? I can see it flashing
Use 4 I/O to control 9 LEDs (9 stages), possible? Since the max stages of using 4 I/O is 12.
