I am trying to control esc using STM32F446RE Nucleo 64 board but after uploading the program nothing shows up.I am using timer 2 channel one.

What is the expected behaviour and what is the observed one? How do you exactly observe it? Read out and check the content of relevant TIM/GPIO registers.

PS. What is "esc"?
