Hello, is it possible to use the virtual pin name in the BLYNK_WRITE macro from the data structure?
The code crashes, it’s easier and clearer for me than V0 …
Does not work with BLYNK_WRITE(v_pins.test) but work with BLYNK_WRITE(V0)
Error:
sketch_nov22a:20:19: error: expected initializer before ‘.’ token
