Hello,
It seems that i have destroyed my apa102 led strip due to a short circuit on the raspberry. Unfortunately the RPI was damaged aswell so i had to replace it.
How can i specify which leds are burned and which are still good or if all of them are gone? If i measure the voltage between GND and DI or CI it is way to high (close to 5V). If i remember correctly it should be only arround 1V.
Thanks in advance
