function in not loaded error

[CARLOS GARZON]

Hello:

I have a problem on runtime error do know where to load the function

power = engine.output_variable(“Power”)

ambient.value = 7
enable.value = 1
normActivity.value = 250

engine.process()

print(“Salida en LED: “,power.value.as_integer_ratio)

RuntimeError: function ‘le(Ambient,NormActivity)’ is not loaded

Hi,

I am very sorry for such a late response. It was classified as spam and I had no visibility.

The problem is that fl.Function(“LED2″,”le(Ambient,NormActivity)”,engine) does not load automatically, which is a bug. You have to load that function manually.

led2 = fl.Function(“LED2″,”le(Ambient,NormActivity)”,engine)
led2.load()
# And then add into your controller.

Cheers,

Juan
