Ticker class call in C++ mbed

Question

I'm writing a programme that generates a fixed frequency using a ticker in mbed environment. I'm still at the begineing so it's a little bit messy.

Answer 1

In the attach line change &this to this. this is already a pointer to self, you don't need to take the address.

flipper.attach(callback(this, &Speaker::flip), 0.5/frequency);
