TypeError in Viper routine but no floats in sight

[pythoncoder]

That shouldn't happen.

I've reviewed my own use of Viper and I don't generally have type hints within the body of routines, however they are always present in the definition. self doesn't have a type hint, but all other args do, e.g.

Code: Select all

    @micropython.viper
    def _setbuf_fixed(self, line: int, fixed_value: int):

I do think you should have a type hint for the timer instance.
