FastLED with analogRead() does't work

Other Hardware LEDs and Multiplexing

I used this:-

#ifdef USE_POT
 //-- use analogread, NOT WORK
 potVal = analogRead(potPin);
 potVal = 42;
#else
 //-- WORK FINE
 potVal = (int)random(0, 1023);
#endif

And it worked fine at a steady red.

I haven't got a pot wired up at the moment, but as you can see the analogRead function is being called. Therefore I suggest your pot has not been wired up correctly.
