Hello Pete
First let me apologize because what I am about to ask is not a Blynk related issue. But since you have experience with the ESP range of controllers and already have seen what I am trying to achieve, I would like some advice and assistance. I am stuck at the moment trying to get my code to compile for the ESP32 board that I am transitioning to from the Arduino Mega. My program compiles and runs on the Mega but does not compile for the ESP32. This is the error message that is produced:

is actually this line in my program FastLED.addLeds<WS2812, DATA_PIN, GRB>(leds, NUM_LEDS);
Strange thing is that the āBlinkā example code on github,here., which uses the same line of code, compiles successfully

I have tested and successfully compiled the Blink example code
. Changed that to a 1 and it worked. Thanks Pete.
